What are the Biggest Tires you can run on 4Runner (Stock, Lift Kit, and Leveling Kit) – Largest Tire Size on 4Runner Explained

We have had a few questions on the biggest tires you can fit on your 4Runner. Asking this question on a forum might get you a few snarky comments, but it is welcomed over here. We got this question again and figured we should probably write something about it.

If you are asking yourself what the largest tire you can fit on your stock 4Runner is, you will find it here. If you want to know what the largest tire size you can fit with a lift or leveling kit is, we are also going to be covering this.

This should serve as your complete guide to the 4Runners tire size (for most people anyway). If you have any questions about tire size on your stock, leveled, or lifted 4Runner, you are in a safe place. There are no forum trolls on this page waiting to bark at you for asking one of the most common questions in off-road history.

I had these question at one point as well:

  • How big can I go?
  • Do I want to go as large as possible?
  • What are the benefits of going bigger?
  • What are the downsides of going bigger?
  • At what point do I need a BMC (Body Mount Chop)
  • Should I keep my stock wheels?
  • What is the best wheel size for Off-Road use?
  • What are the best All-Terrain tires?

The most common questions about Tire Size:

  • Largest Size Tires on Stock 4Runner?
  • Largest Size Tires with Leveling Kit?
  • Largest Size Tires with Lift Kit?

17″ Wheel/Tire Options (Examples for Rubbing Vs. Non-Rubbing)

Resources and Guides: 

The best resource out there for checking tire sizes and exact diameter measurements are tirerack.com and Tacomaworld.com (Tire Calculator). You can use both of these websites to check your tire size diameter and height and width to make sure the tire will clear your mud flaps, body mounts, fender liners, body plastics, firewalls, and pinch welds/seems.

You should always consult with these websites before you go larger on tires. One of the most important aspects of buying new wheels is the correct width and offset as well as backspacing.

If you don’t do your research on Width, Offset and Backspacing, you will learn how to do a body mount chop and trim multiple areas of your wheel well. But this is also not a bad thing, either.

Body mount chops are nothing to be afraid of. Once the edge of the body mount is cut off, you paint over a new piece of metal and it looks factory again. When and if you go to sell your 4Runner, it’s likely no one will notice.

How to Check Tire Size and Wheel Size Fitment

Treadwright Mud Terrain Tires

If you are looking to figure out if a wheel fits a tire size, head over to ToyoTires.com.

They have a really good “recommended” wheel size for whatever tire size you enter. Go to ToyoTires.com and enter in your tire size. From there, Toyo will give a list of their tires. Select a tire that you have or are considering and then you will see a section labeled “APPROVED RIM WIDTH RANGE (IN.)”.

This will give you a range of wheel sizes that are compatible with the tire size you enter.

From there, you see what wheel sizes will fit that tire. If you do not see your wheel size there, that doesn’t mean it won’t fit. It just means that it is not “recommended”. What does this mean? Maybe the tire company will not warranty the tire if some type of defect occurs. In any case, call your local tire shop for details on this one.

When Choosing Wheels (Look at these specs):

Cooper Evolution M/T (Mud Terrain) Tires

Our wheel specs: 

  • Bolt Pattern: 5th Gen = 6×139.7mm or 6×5.5
  • Wheel Bore: 5th Gen = 106mm
  • Offset (-offset pushes the wheel out giving you a wider stance. +offset pulls wheel into the wheel well)
  • Backspace (Similar to offset – the space between center tire and inside wheel)
  • Rating (Weight rating wheels were designed for)
  • Weight (lb)
  • Lug Type (tapered “conical” and radiused)
  • LipSize (in)

Here is a good guide on offset and backspace to help you understand the differences.

Note: When shopping for a wheel, I look for a wheel with at least a -6mm offset or higher. Maybe a -10mm or even higher offset. This is going to push your wheel out of your wheel well which may eliminate the need for wheel spacers, but not always, all while providing a wider stance.

An extreme example of offset is the -38mm SCS (Stealth Custom Series) F5. That is going to push your wheel out of the well 1.5″ which is a lot. Most wheels are going to come in a 0mm, -6mm (.2″) or -10mm (.4″) offset. If you buy a wheel at this offset and are looking for a very wide stance, you want to add a set of wheel spacers to widen your stance even more.

Stock wheel size on our 5th Gen

  • The SR5 comes stock with 17 x 7, 4.5″ backspace.
  • The TEP (Trail), the TRD Pro, and the TRD Off-Road come with 17 x 7.5″ and a 4.875″ backspace.
  • The Limited Edition comes with 20 x 7 with a 4.5″-inch backspace. 

Largest Tire Size on 5th Gen 4Runner?

Mud Terrain Tires

Stock 4Runner?

The short answer is 32″. Our stock 4Runner has a 31″ tire (265/70R17 – 31.61″). Making the jump to a small 32″ tire should be fine on stock suspension. You want to make sure this is a smaller 32″ tire and not a larger 32″ tire. Some 32″ tires measure closer to 33″ tires.

For example, a 32.06 is basically a 32″ tire, while a 32.79 is closer to a 33″ tire. If you get a 32″ tire that is closer to 33″, you may end up doing a BMC and other modifications like a fender liner push back to ensure your tires will not rub without a leveling kit. If you want a larger tire, you should really look into a leveling kit or lift kit, though.

Most owners make the jump to a 33″ tire (285/70R17 – 32.71″). Moving up to a 33″ tire requires a leveling kit or a lift kit. If you have 3″ of lift in the front, then moving to a 33″ tire should be fine, but there are 33″ tires that will rub even with 3″ of lift. It may seem confusing but every tire is different due to the tread pattern, and general design.

With 33″ tires and 3″ of lift, you may have some rubbing on the fender liners – which is a really easy fix that no one will notice. If you are trying to avoid trimming fender liners, BMC and other areas of the well, stay away from 34″ tires or large 33″ tires as this will absolutely cause serious rubbing all the way around. 34″ tires (285/75R17 – 33.8″) will rub on the front fender liners, and body as well as the body mounts and possibly even the firewall.

Largest Tire Size with Leveling Kit?

The largest tire size you can run with a leveling kit is entirely up to you. With a 2″ leveling kit, you may still be stuck at a small 32″ without any modifications like a BMC.

If you move up to a small 33″ (32.7″) tire with a 2″ leveling kit, you will likely need to do a fender liner push back.

Small 33″ tires are probably as big as you want to go with a 2″ leveling kit unless you want to get into more adjustments than just your fender liners. Which, at the end of the day these adjustments are not hard, they just require some testing and consistent adjusting until you no longer have rubbing.

Largest Tire Size with Lift Kit?

Most owners that have a lift kit are still at the same level of a leveling kit, but possibly up 1″. The basic suspension lift kit for a 4Runner is 3″ – 3.5″. 33″ tires are usually fine without any major modifications here, but it also depends on the exact measurements of your 33″ tires and the terrain. If you Mud Terrains with large tread blocks and lugs, you may be closer to rubbing as opposed to mild All-Terrain tires.

Small 33″ (285/70R17 – 32.71″) tires should clear fine with 3″ lift kit but if you get into 33.5″ tires or 33.7″ tires, you will need to do some adjustments for sure.

With 33″ tires, you still always run the risk of a BMC, fender liner mods and actually trimming off parts of your body. Just keep in mind, that if you go with 33″ and up, you will have a higher probability of adjustments to make.

At 34″ tires with a 3″ Icon suspension lift, we had to do numerous modifications (fender liner, body, pinch welds, rocker panel caps, etc.).

Wheel Spacers & Offset (same concept)

When you add wheel spacers, this may cause more rubbing than before. After we installed our Icon stage 2 suspension and added Spidertrax wheel spacers, we had more rubbing on the fender liners and body.

With the 2″ (50.8mm) spacers (for example), you are pushing your wheel and tire out of the well 2″.

Without spacers or little to no offset, your tires are sitting in the center of the wheel well, for example. In this position, they have plenty of room to turn inward without rubbing because your fender liners are curved inward. But, once that wheel comes out of the wheel, that outside edge of the inward curve (body and fender liners) then becomes a collision course for your tire thus causing the rubbing.

So keep in mind, the more negative (-) offset your wheels have, the more likely you are to rub on the fender liners and body plastics.

Common examples with a 3″ of kit:

  • 275/70R17s (32.16″): Rubbing unlikely
  • 285/70R17s (32.71″): Mild rubbing, fender liners and plastics, BMC likely, body trimming optional, rocker caps questionable.
  • 285/75R17s (33.8″): Prepare to trim and chop mostly everything.

With 33.8″ (34″) tires, we had to chop our body mounts, push back our fender liners, slice big sections off of our fender liners, slice sections off our rocker panel caps, new lines in our 4Runner’s body, smashed in the pinch welds, and removed the mud flaps.

It was a lot of work to get things to work and constant testing but the off-road result with 34″ tires was well worth it.  Once you get your 34″ tires to comfortably fit inside your wheel well, wow. The results are amazing. Just make sure you have an adjustable suspension (Icons, KINGS, FOX, Radflo) or any others so you have more flexibility in your adjustments.

Do I want to go as large as possible?

Not always. Going with the biggest tire you can mean that you need to cut your body mounts, trim your fender liners and cut into your 4Runner’s body. If that is something you are interested in doing, then, by all means, go all out. If we could have gone larger than 34″ tires, we would have. We likely will in the future.

What are the benefits of going big?

Having bigger tires allows you to clear more obstacles off-road. With larger tires on your 4Runner, you have more grip on all types of terrain. There is a huge difference between 33″ tires and 34″ tires and 35″ tires when you are off-road. I have had 31″ tires, 33″ tires and 34″ tires and with 34″ tires, everything is easier. It also depends on the driver and how much experience you have. Also airing down your tires has a big impact on what you can do and what your tires can grip.

What are the downsides of going big?

Gas mileage and trimming 4Runner liners and plastics. When you make the jump to 33″ and 34″ tires, you will see a decline in gas mileage. Even if you regear (change the gearing ratio), you will still see a slight decrease in gas mileage with larger tires.

The good happy-medium tire size is probably 32″ – 33″. With 33″ (285/70R17) tires, you can still trek just about anywhere you want off-road while still maintaining some decent MPGs.

A larger tire has a greater circumference. So the wheel turns fewer revolutions to go the same distance as a smaller tire.

How does that affect RPMs? 

So you’ll be increasing tire size by 10%, so you’ll decrease engine speed by 10% too. Assuming you’re running about 3000 rpm at 70 mph with the small tires, you’ll drop 10% with the big tires. 10% of 3000 is 300, so you’ll go down to 2700 rpm. Jalopyjournal.com

Re-Gearing?

Re-gearing your 4Runner is not cheap. The cost of Nitro Gears is about $1200. Depending on where you take your 4Runner, you can spend $1000-$1500 in labor. And while you have IFS apart, you might as well add a front locker. An ARB front locker is $1000. All out the door, re-gearing and locking the front diff can run you around $3500.

With 33″ tires, re-gearing is debatable. Very few guys do it. With 34″ tires, gearing is highly recommended, and most shops will recommend a gear ratio of 4.56. If you are moving to 35″ tires, you can go with 4.88s or even 5.29s. This completely subjective though and many guys will argue this point back and forth.

Just know re-gearing can get expensive but is highly worth it if you decide to go with larger tires.

At what point do I need a BMC (Body Mount Chop)

This all depends on what lift kit or leveling kit you have. In most common cases, you will want to go with 33″ tires. With 33″ tires, you need a 3″ lift in order to avoid a BMC, but not always. Once you go to 33″ tires, you will likely need to chop the body mounts.

If you only have a 2″ leveling kit with 33″ tires, you will need to do a BMC for sure.

With 34″ tires and 3″ of lift, you will need to do a BMC, trim your fender liners, push back your fender liners and cut into your 4Runner’s body.

Aftermarket UCAs (Upper Control Arms) are also recommended to get better caster (to push your wheel/tire away from the body mounts) but not always needed. For this, you want to contact a good off-road alignment shop in your area. We live in Sacramento, CA so we go to Stellar Built. They do the off-road alignment (yes it’s different), installs and much more.

Should I keep my stock Wheels?

Always a good option. There is nothing wrong with keeping your stock wheels and making the jump to bigger tires. The stock 17″ wheels are great for on-road and off-road use. Moving to an aftermarket wheel is only more expensive and oftentimes, more confusing.

If you are a first-time owner and not sure about aftermarket wheels, just grab a new set of larger tires and go experience what your 4Runner has to offer.

What is the best Wheel Size for Off-Road Use?

Typically, the smaller the wheel size, the better your off-road performance will be, but not always. When it comes to our world, 17″ wheels are probably your go-to size. You want to stay away from 20″ wheels on your 4Runner if you plan on frequent off-road trips.

When it comes to a smaller wheel size, you can air down the tire pressure further than you can with a 20″ wheel. Having less air pressure in your tires means your tire will have more flotation and grip the terrain much easier than at full PSI where the ride is stiffer.

With less air pressure, the ride will be smoother and less bumpy, all while gripping the terrain much more efficiently.

What are the best All-Terrain Tires?

The section of copy came from another post we wrote on Mods (Part 1). All these tires are based on a 285/70R17 (about 32.71″ depending on tread). Always check prices online Vs. your local tire shop. If online is cheaper, just have them shipped to your tire shop.

For the best AT tire or MT tire, Cooper offers some pretty great options for just about every driver. Of course, the BFG KO2 is a popular brand but Cooper has quickly become one of the go-to brands in the Toyota SUV/Truck market.

Hey Brenan, love the site it’s been super helpful in looking for options to add to my 4runner. I’m looking to run 285/70R17 KO2s can I put 2/2 spacers on the suspension and do a BMC and fender trimming. Or should I put on the 3/2 pro comp spacers that you mentioned in another answer to a similar question.

Just put 275/60 20 Nitto Terra Grapplers on my 2016 and there is no rubbing with basic turns. Took front mud flaps off. About to level the front by 2” but I’m sure it would rub with some flexing if I didn’t. About a 1/2” clearance at the closest point.

Hi Brenan,

I’m either leaving my 2018 sr5 stock or getting it leveled. Thinking of getting Some Rhino Warlords’ (see below). With a large offset (-12), would 275/70/17 still fit without rubbing?

Part Number Size PCD Offset

First off, how did you get them to cut the front bumper at the Port (if I’m correctly understanding you to mean the Port of Delivery)? … Anyway, assuming you’re now running the stock 265/70/17 tires on the 17×7 TRD Pro wheels, then a 275/65/18 tire, on an 18×9 wheel with 0 offset, would be ¹⁄₁₆” closer to suspension components and the rim would be ²⁷⁄₃₂” closer to suspension components. As for the tires and fenders, each tire will stick out ³⁄₈” farther than what you have now, and each rim will stick out 1 ⁵⁄₃₂” farther than the TRD… Read more »

I didn’t get them to cut the bumper. Toyota cut them before I took delivery. I looked inside and you can see where they shaved off the front inner bumper. My car had the xp predator package that came with the trd wheels. Yes, I have the 265/70/17 wrangler dura tracs on there now. I decided to go 275/65 and live with the fender liner/mud guard rubbing if it happens. I will install and report back! Thanks for your help!!

I have a 2018 TRD Offroad with KDSS, and I just put on the King kit from Toytec set to 2in. I have Wrangler Duratrac 265/70/17 on stock wheels, and now they look tiny. I was hoping to go bigger, but this sounds like the biggest size I could do is 275/70/17. That’s only going from 31.6 to 32.2 (and the duratrac isn’t available in that size). Will that even be noticeable? So are there any guesses about what else I could do and what might be involved? I don’t mind a few mods to fit tires, but I don’t… Read more »

Mark, I just finished a 3″ toytec lift on my trail without kdss and I have 305/70/17 on the stock wheels. I made no BMC or modifications except the removal of my mud flaps. I did originally go with the 285/70/17 but they were to small and looked like an F250 out of factory. I had Cooper STT Pro and ended up with KM2’s. Personally I would stick with the TRD wheels as those are really nice, try the 285/70/17. Remember Discount Tire has a 30 day return/exchange period, I took advantage of that. The dimensions of the 285/70/17 are… Read more »

A local tire shop gave it a try, but they did rub and so they took them off. They are ordering a set of Falken Wildpeak AT3Ws 275/75/17s. They are a virtual exact size match, on a 7×17 wheel with 4mm offset, for the OEM 20-inch wheels (15mm offset) and stock Yokohama Geolandar G96B all-season tires.

My tire place in town won’t mount tires on my Ultra Phantom wheels I purchased online. They are saying that every 4Runner they put tires on with aftermarket rims hasbhd vibration issues. Has anyone had any problems with this? Also the rims I purchased are 17×8 with a +1 offset. They are also telling me this won’t work. Any thoughts?

The vibration issue with aftermarket wheels is most often reported by people using lug-centric wheels instead of hub-centric wheels like Toyota OEM uses. Make sure your wheels are a hub-centric design like the ones Toyota uses for these vehicles. SCS and RRW among other manufacturers make wheels like this specifically for use on 4runners and Tacomas…

We just bought our first 4Runner and I’m super glad I found this site.

Therefore, I beg your indulgence. After reading your post about maximum tire sizes I’m considering going with a conservative 275/70/17 tire. I want to put them on bead lock wheels that I’ll swap out with my stock tire/wheel combo before hitting the trail. Q1: Do I understand the article to suggest that 275/70/17 tires… Read more »

I’m looking for real bead lock wheels. My goal is simple…come to think of it, I’m simple…at least that’s what people tell me, but I digress. I’d like to put some dedicated off-road tires on a set of bead lock wheels that will not rub on a stock 2019 TRD Off Road. (I’ll occasionally put them on the 4Runner at home with a floor jack before going wheeling and take them off when I get home) Since I will not be running them daily, I’m not especially concerned what the wheels look like (well, pink isn’t an option). I’d be… Read more »

Brenan,
I would like to know if you think I could run Duratrac 285/70 17″ on our 2019 TRD Pro with out any modifications or rubbing issues. I don’t know if the TRD Pro setup will allow.
Thanks

Brenan,

I am looking into a 5″+ lift on my 2016 4 runner trail. I do not have KDSS but am looking to get as close as i can to 35’s.

I have read the articles over and over and don’t see much information on anything greater than 3″ lifts. That said, am i capable of purchasing a 5″+ lift and fit under there something close to 35 or even 35’s? Or will this require a major BMC and mods to get them under there?

Brenan, thank you for this article. I appreciate the time and effort you put into writing it. I saw the comment you left someone referring them to read Clint’s article on 275/70R17 Cooper tires which I enjoyed as well. I am really stuck between the BFG All-Terrain T/A KO2’s in either the 275/70r17’s (32.2 diam.) vs 285/70r17’s (32.8 diam.) My head wants the 275/70r17’s bc I commute about 60 miles Monday – Friday.

I have 275/55/20 on my 2011 limited. Wrangler adventurer all terrains with 64k miles on them. They road really rough after 55 but the tread lasted. I just replaced with exact same tire. Also pull a 3500lb camper up and down the mountains with same tires. No flat spots and awesome in the snow and asphalt. Just my 2 cents

Great information here, I have a pretty good idea of what I can and can’t do now. I just wanted some clarification before I went into it. I have a stock 89 4runner, wanted to put it on 17’s with -12 offset. Later in the season I plan on installing a 2″ OME lift and setting her on 35’s. I don’t have the time for that now and need tires. So my question is can I fit 32’s on 17’s with out substantial rubbing or no rubbing at all? Recommendations welcome, tha is for your time! 🙏

IIRC, I ran 32×11.50×15 on my 1987 4Runner years ago. I don’t recall any major rubbing. But I think anytime we toy with going up in size, we need to be prepared to live with rubbing as a possibility and/or options on what to do when it does. I just put 285’s on my 2011 4R and it rubs slightly. My wife and I were prepared and I know what my options are.

I am putting a 6112 / 5140 Blistein Lift & Icon 2″ Springs for the rear on my 2016 Toyota 4Runner SR5 Premium. Was going for the lifted and level look and to stop the nose dives….Was looking to go with the Cooper SST Pro’s and in 265/70/17….Would this look good with this lift and tire?? Was also considering 275/70/17, but don’t know what to get. Cooper doesn’t make this for the SST Pro so would need a different make if I go this route. Any help would be greatly appreciated!! Thanks!!

Hope you can advise. Have a 2013 Limted and want an All Terrain tire that the 20×7″ rims can’t handle. Have had the BFGoodrich AT KO2 on previous Jeep GC and 2001 4Runners so that is what i look at first. Thinking of new 18″ wheels, and the chart is very helpful with tire size options that won’t rub, but no idea on width or in chart what “space needed” referrs to?

I would like to know the best tire for a stock 2011 4Runner limited. Tire size 275/55/20. I ran Goodyear wranglers in the same size for 50 thousand miles and they’re great tires but uncomfortable. I had them balance it as well as could be and still have a lot of shaking in steering wheel around 55-65 mph. Any advice would be great before I buy some new ones for this season. Thanks

I am wanting to put 275/55/20 KO2 on it, but dont know if it will rub because of the extra 1/2″ on a stock xreas suspension. Please help!

Long time 2006 4Runner owner but new to the lift world as of today. Had a 2″ leveling kit installed with Bilstein 5100 Series Front/Rear shocks. Currently running old 265/R65/17 Big O Big Foot tires that are in sore need of replacement anyway and look too small now for the lift. I’d like to have a bigger tire using my stock rims. What size tires would you recommend? 275/70/17 (BFG All Terrain T/A K02 for example), 285/65/17, or 285/70/17’s and that avoids rubbing/modifications?

Awesome site for this noob! Thx!

Taller tires will lower RPM, not raise them. At highway speeds, you’ll probably increase gas mileage.

Buying a New 2018 off road premium as we speak, They are upgrading the wheels to the trd black 17″ and i asked for 275/70r17 BFG ko2 AT, just confirming this will fit with no issues on the stock suspension? Or I can always lift it 3″ and get even bigger tires, but that would be overkill as I’m a road queen.

Few questions:
1. Did you regear? if so, when did you do it and how long did you wait before doing it. 4.56 or 4.88?
2. If not, how is it so far and how long has it been?
Thinking of going to 34’s. I don’t mind the trimming and I’m getting a BMC soon anyway. 35’s are just TOO much work.
Thanks!

What kind of mileage are you getting on 285/75’s, and how bad is the power loss? I have an icon stage 2 kit that I am installing with the factory TRD OR wheels on my ’18 and am stuck between 285/70 or 285/75 ST Maxx’s (Both E range tires). I off-road maybe once a month or once every other month but drive 60 miles a day mostly highway. If I go 285/75 I will eventually regear, but that will most likely be early 2020.

one thing to keep in mind is that the narrower and/or the smaller the tire diameter is the less likely it will rub. Larger AND wider tires will rub more. Also adding wheel spacers or using aftermarket wheels with more negative offset will cause rubbing more

I have researched the “Cookie Cutter” tires a lot in the 155/80 17 size with a focus on the Wildpeak AT3W. Not a ton of info out there, but people seem to really like them. Rubbing does not seem to be an issue with stock offset, there are even people running them with no lift without rubbing (likely no flaps) With offset wheels people seem to have at least a minor lift. Great traction, strong side walls (since really this is a dually size), smooth running, better steering response, better gas mileage (less rolling resistance) and able to air down… Read more »

Tall and skinny is the way to go, especially in the snow. I had an 82 Chevy Scottsdale pickup truck years ago with a 4 inch lift and 35’s. In the winter time I needed a tire that didn’t look too small so I went with these winter/studded 225/85/16 tires and they were amazing in the snow. Such a skinny tire along with the studs and all that weight from such a large truck made it have amazing traction in tthe ice and snow.

Great write up. I purchased the Dobinsons 2.5″ front and 1″ rear lift kit. Do you think 285/70/17s K02s will fit without rubbing? I didn’t want to go 3″ in the front to stay away from changing upper control arms. Also, I wanted a very level looking lift. There is a ~2″ rake on my 2019 TRD Premium.

Your post made it seem unsure if modding the BMC and fender liner mod is needed.
