Going with 34″ Tires on 5th Gen 4Runner – Toyo Open Country AT 2
34″ Toyo Open County AT 2 Tires (285/75R17) & 17″ Fuel Wheels
With the addition of bigger tires, you will need to do some trimming and cutting of the wheel well.
There was quite a bit of hesitation when we decided to go with the 34″ tires. But, at the end of the day, we are glad that we did. The 34″ tires give it a pretty mean stance and will be more capable offroad.
We decided to go with the 34″ Toyo Open County All Terrain 2 tires (285/75R17), and the 17″ Fuel Anza Bronze wheels on the Trail Premium.
Our next step after getting these installed was straight over to the body shop to have the Body Mounts Chopped. Once we have the body mounts chopped off, we can start trimming the wheel well.

What is like driving with 34″ tires?
It is quite a bit different compared to 32″ tires. When we first pulled off with the new tires, you can tell it was a bit sluggish.
I will eventually need to regear the 4Runner – thinking maybe 4.56 or 4.88. Still unsure of the direction right now.
It is a good thing my commute to work every day is less than a mile. My office is across the street from my house which makes for a nice slow comfortable ride. With that being said, it doesn’t bother me that much as of right now.
It really depends on how much you off-road. We go out as often as we can and we don’t always write blog posts for places we go. And, sometimes we hit the same places that we have gone in the past, so it does not make much sense to write another post on them.
17″ Fuel Anza Bronze Wheels
These wheels are stunning. They are not a true beadlock, although Fuel does make one wheel that is a true beadlock. Also, the beadlock on these one-piece wheels are not removable. If you do paint or remove these beadlocks, it will void your warranty.

Body Mount Chop
The body mount chop is a well-known mod if you are running larger tires. If you have a 2.5″ suspension, you can run 33″ tires and be fine. In most cases, no modifications are needed but it depends on the exact size. This is hit or miss though. Some guys run 33″ tires and need a BMC and some do not. It all depends on the exact tire and wheel you are running.
If you go with 34″ tires, you will need to chop your body mounts.
On a previous post, we installed 31″ KO2’s on a 3″ Pro Comp leveling kit and there is plenty of room. No need for the body mount on this one. 31″ tires really fit under anything. Even a 2″ in the front and 1″ in the back, 31″ tires will have plenty of room.
What is a Body Mount?
The 5th Gen 4Runner is a body on frame. Maybe the last of its generation. The frame holds the engine, suspension, and supports the body with rubber bushings. The body mount and body mount bushings cushion the ride, but over time they break down.
The actual body mounts that we are referring to are underneath both the front driver and passenger side, closest to your rocker panels/rock sliders. These body mounts have a steel casing that encloses the actual body mounts. This body mount encloser needs to be chopped off as it will interfere with your larger tires.
Trimming Plastic Fender Pieces?
There are a couple of different places where you will need to modify your fender well parts on top of chopping your body mounts.
Areas we will cover soon:
- Trimming the body
- Push back and relocate fender mount point
- Trimming front and rear fender liners
- Trimming plastic rocker panel caps (valance caps)
- Bending pinch welds
- Body Mount Chop (BMC)
- Optional: Bend pinch seam
- Optional: Remove splash guards
Body Mount Chop + Trimming Body?
Pictured Above was cutting that we already made for our leveling kit, just to give it a little more room. You can see the uneven cuts from what we had done before. We are going to go a step further with the new 34″ tires. That post will come soon.
You will need to chop and trim up your body. Yes, you will literally need to cut a piece off of your pretty body.
The body mount chop will only prevent the inside area (rear of the wheel well) from rubbing. The trimming of your body will need to take place in the front of the wheel well, closest to your grill.
By chopping the front of the body fender, you will prevent rubbing on the front of the wheel well.
