Introducing the MORRFlate – The 4-way tire inflator kit from My Off-Road Radio
If you are familiar with airing up and down your tires, it can be quite the process. With the standard inflator, and deflator, combined with a portable air compressor, you have to manually air up and down each tire individually.
There is a solution to individual airing up and down your tires, look into a 4-way tire inflation system. If you are looking for a high-quality 4-way tire inflator and deflator system that will save you time and effort, we found it.
Tyler from My Off-Road Radio designed one of the coolest tire inflation/deflation kits I have seen, the MORRFlate and the MORRFlate+. There are quite a few people in the off-road community who build their own DIY 4-way inflation kit, but none quite like the MORRFlate.
If you are looking for an efficient off-road tire inflator and deflator system, you should consider checking out the MORRFlate. Everything from the fittings to the manifold and the tubing to the clamps is truly impressive. You can tell that a high level of thought went into the design, production and everyday use of this product.

MORRFlate Off-Road Tire Inflator & Deflator
After nearly 3 years of research and product testing, the MORRFlate is now ready for the masses. This is a complete plug-n-play inflator/deflator kit that is ready to use out of the box.
There are a few key components that make the MORRFlate so badass. Unlike many other inflator/deflator systems on the market, the MORRFlate tubing does not kink or bind. It is incredibly strong, will never hold memory when stored, and temperature resistant (-40 to 140 degrees). The fittings are all high-quality and the air chucks that fit onto your valve stem are strong and efficient.
The Haltec air chucks default closed (they won’t let air out when pressurized). They have 3 lock-on-teeth to lock onto your valve stems (no more air chucks coming loose and leaking air!). The teeth don’t engage until you engage the locking collar, which helps your valve stems and the Haltec teeth last longer. To pull them off, just pull the locking collar away from the valve steam, thus releasing the teeth and the air chuck all in one swift, easy movement. Read more about the MORRFlate here.
What I love about this inflator kit is that it’s extremely pliable, easy to handle and can be stored in almost any location you can imagine.
Some other inflation kits come with air tubing that is awkward, pre-coiled and just difficult to store. Even that popular Husky hose (blue air tubing) is a pain in the ass when it comes to storage. It’s large, bulky and difficult to find a home for.
When I first used the MORRFlate, I was sold. I might never use another air inflator/deflator system again.
There is a MORRFlate and then a MORRFlate+
My Off-Road Radio offers a few options for their air kit. You can choose a kit that accommodates your wheelbase, and then add MORRFlate leads if you need them.
On a side note, the wheelbase on the 5th Gen 4Runner is 112″.
- The MORRFlate is the standard inflator/deflator kit offered by MORR.
- The MORRFlate+ is a longer version for wheelbases longer than 120″ but shorter than 155″
- Optional MORRFlate Leads: An 8ft lead to go from wherever you have your air source located, to the MORRFlate.

The MORRFlate also comes with a 1-year warranty and a 60-day no-questions-asked return policy.
Using the MORRFlate 4-way tire inflation system
Your MORRFlate comes as a plug-n-play kit, ready to go out of the box. There is no setup required. There is no installation required.
Just throw it in your rig and go explore!
The MORRFlate is simple to use.
In order to air down, clip on the air chucks onto all of the tires you want to be aired down, then open the ball valve! You can also add an ARB deflator to check your pressure. Once you have reached your desired air pressure, close the ball valve and remove the air chucks. That’s it.
Now, all four tires are at the exact same PSI.
To air up, connect all of the air chucks to the tires you want to be aired up, then connect the ball valve to an air source, open the ball valve, and turn on your air source.
To check the PSI of your tires, turn off your air source (if using a compressor that does not have a pressure switch), close the ball valve, wait 5 seconds for the tires to self-equalize, then attach a gauge to the valve stem on the manifold. The reading is what all the connected tires are at.
MORRFlate is Functional and Convenient
The big thing to keep in mind is that the functionality is awesome, but it’s the convenience factor that moved me to switch my process.
Just the pure ease of use and how relaxing it makes airing up and down.
I literally sit around talking to people at nearby trucks, or have a beer, or sit on a log and lounge back while everyone else is hustling around their rigs, squatting down over and over, checking and re-checking PSIs, moving hoses around, etc.
There are other solutions out there that require drilling into your trucks wheel wells in order to get hoses and chucks attached. And as these solutions are nice, they are not for everyone.
If you want a plug-n-play convenient air inflation/ deflation kit that does not require drilling and is incredibly portable, the MORRFlate is a solid option.
Tyler at My Off-Road Radio is knowledgeable, reliable and pretty dang skilled behind the wheel. Simple as that.
If you have even the simplest of questions, reach out, his support is top notch as well.
Amazing tips. How to use tire inflator perfectly and effective. Video is amazing and useful. Thank you for the post.
I would agree with you that tire inflators are really important to have in your car. Like you say, it can get your truck or car on the road in no time. Flat tires happen all of the time. It would be nice to be able to pump it up on the street. I’m going to get myself one of these! keep blogging
The chucks look pretty beefy, will they connect fine with the 4runner’s stock trail/TRD off-road wheels?
emailed you 🙂
Hey Kevin! They sure will 🙂 The really nice things about the MORRFlate chucks is that they don’t physically lock on to your valve stem until you engage the locking collar. This means that your valve stems won’t get torn up over time like almost every other air chuck out there. And with there being 3 locking teeth, once it is on, it will stay on and keep a solid seal until you disengage it 🙂
Say no more, already ordering! Also need to get a lead but not sure if my MV-50 has a auto or milton coupler
Brenan, what pump are you using with the MORRflate system and what are your air-up/air-down times? Also, are you running 33’s? Thanks
Currently running the Smittybilt compressor and 33.8″ tires. The Smittybilt + MORRflate is a great combination. I will update the post with accurate numbers asap. If curious, you can see my numbers without the MORRflate on the Smittybilt overview.
I have rubber valve stems (no pesky TPM for me!). Will the MORRFlate work with rubber valve stems? The fitting look a bit heavier is why I ask. Thanks!!
Definitely will! As long as you have more than 1/4″ of thread down your valve stem it should be great. (We only use rubber valve stems as well… Anyone who uses metal valve stems off roading is just begging for problems! You’re a smart guy Scott!)
Did you just cut the hose for the Smittybilt and add a male hose connector to make it work? and how safe is it to do so?
Hey there PJ. Yup, that’s exactly what Brennan did. It’s very easy to do. You just need a Universal coupler with a female 1/4″ NPT on one end. Then a Male 1/4″ NPT to a 3/8″ hose Barb. And a small (size 4???) Hose clamp. And some nylon thread tape or thread sealant. Cut the old fitting off of the Smittybilt hose, as close to the fitting as you can. Then put the hose Barb in the hose, attach the coupler to it, and put the hose clamp on around the section of the hose with the Barb in it. This will also allow you to use your Smittybilt in more situations by having a coupler on it that can do both IM and Automotive adapters. Cheers!
Perfect! I’ll be placing my order on the MORRFlate tomorrow then!
Can I use this on my sports cars (corvette / Ferrari) for track day pressure adjustment?
Will the chucks work on ordinary valve stems?
Hey Ken, it will definitely work on ordinary valve stems. The thing about track vehicles, is that I know the vehicle performance is highly dependent on accurate and specific tire pressures. What I don’t know, is if track vehicles are sensitive enough to warrant different PSIs in each tire. The MORRFlate will automatically make every tire that it is hooked up to, the exact same PSI. So, if you wanted to run different PSI in the rears from the fronts, you could just do 2 tires at a time. If you want the exact same PSI in all 4 tires, then the MORRFlate excels at that. Let me know if you have more questions!
Hi, I’m a new to airing down and back up. Just did it for the first time last weekend while at Hollister hills. Is there a demo video on how to use this system? That’s how I learn on how to do most of my car stuff now days. This sounds pretty awesome though. I may be jumping on this deal pretty soon.
Hey Hey! There isn’t as of currently… but we are going to be making one this weekend! We should have it up and ready to go by the end of next week. I will hand the link off to Brenan to add to this page when it is all set 🙂 It is fairly straight forward though, just uncoil the hose, clip the air chucks onto all 4 tires, then open the valve on the manifold. Check the PSI at the manifold with whatever gauge you are already using. To air back up, just connect the manifold to your air source (compressor, powertank, etc), and let them fill up. We designed it as completely user friendly as we could. Check back here for that video, or join the newsletter over at My Off Road Radio. We will be sending out an email once the video is up.
Hey Eric! Tyler from My Off Road Radio here. Using the MORRFlate actually alleviates stress on your compressor and helps it run more efficient by splitting it between all 4 tires. Whether your compressor can run for the full time it will take without hitting the duty cycle is another question. If you currently air up your tires with the 88p without hitting the duty cycle, then the MORRFlate will only help things and make your compressor’s job (and life) easier.
If I remember correctly, the 88p is rated for 33″ tires. So as long as your tires are 33s or lower then you will be golden!
Thanks Tyler. That is very helpful information!
Will Viair 88P Portable Air Compressor work with this setup? I mean, will it be too much to handle for the compressor to inflate 4 tires at once?
