My wife would not left me install a lift on her 2022 Jeep Gladiator Rubicon Ecodiesel. The factory All -Terrains had to go. What were the largest tires that would fit on a stock Rubicon Gladiator?

Awesome Overlanding Vehicle But It Needed A Tire Upgrade - I like Mud Terrains For Off-Road
The 2022 Jeep Gladiator Rubicon Ecodiesel is a very capable vehicle straight out of the factory. That did not stop me from modifying it for off-road. After installing a bumper and winch the next step was tires. It should have been the lift but as stated previously my wife shot that down. At least I could replace stock All Terrains with a larger Mudd Terrain tire.
These Stock Tires Had To Go!
The 35's I Chose To Install On Our Stock Rubicon - Had To Fit Stock Jeep 7.5"x17" Wheels
Every decision on my vehicle builds requires tons of research, sleepless nights and great wailing and nashing of teeth. No really, I worry about every detail and hope to make the right decision. My tire criteria constisted of:
Must fit on stock Jeep Wheels.
Must not have poke (stay inside the fenders.)
Great on the trail and pretty good on the road.
Maintain the great fuel mileage we get with the Ecodiesel motor.
Made In USA.
Mud Terrain Tires.
Largest tires that will work with stock Jeep.
Best quality tires I can afford.

I Chose Nitto Trail Grappler 35"X11.50"X17" Mud Terrain Tires Load Rated C
With everything read or heard in my tire research it seemed I would be safe installing 35s on my stock Rubicon Gladiator. Apparently this is one of the most asked questions on Jeep forums. Yes its true and they looked great!
Minor Rubbing On Right Side Wheel Liner At Hard Right Turn
New Nittos fit really well with just a little rubbing at a hard right turn on the fender liner. I drilled a couple holes and zipped tied the liner out of the way. Found some solid attachment points and it has worked ok for several months. Hopefully I will be able to have the 2" Mopar Lift Kit Installed. After that there will not be any problem with rubbing.
Reprogramming For The New Tire Size- The ECRI Wireless Vehicle Calibration Device
This is my second Jeep I have added larger tires to. a Jeep. For the speedometer and transmission to work correctly the the computer must be told what size new tires are.
The first time I used the ECRI reprogrammer was with my Wrangler Willys Ecodiesel.
With the ECRI you purcase the device once. Once you have the device you have to purchase the Vehicle Unlock that allows the device to work. You do this for every vehicle you wish to reprogram. Pay once, use it as many times as you want for that VIN Number. Add a vehicle purchase another unlock.
I like the ECRI because in addition to manually inputting the new tire size, the ECRI also uses GPS to verify.
As you drive with the ECRI plugged in it is tracking the vehicle movement and calculating tires size. Once the 2 arrows are close together on the screen your done. Very acurate.
35's Are Not Actually 35" Tall After Mounting - Whats Up With That?
You can see by the picture of my ECRI results above these 35" tires are not actually 35" tall. They calculated out to 33.64". I'm not sure why tire companies don't list the actual size tire will be. It seems strange.
Gladiator Is Not Our Main Overlanding Rig - My Wrangler Willys Ecodiesel Is
Gladiator is my wifes vehicle. When she comes on the trip we drive it. We also have the Willys Ecodiesel. I love the Willys but it is a very basic vehicle. Small radio, hand crank windows, no clicker. Because of that I got a great deal on it. I have a video and Blogpost describing that Jeep, the build, and how much I paid for it. See it here.
Gladiator Is Amazing With New Tires - They May Be The Most Important Part Of The Vehicle Build
So far we have taken the Gladiator on 2 Overlanding trips towing our Exventure XV-3 off-road trailer. First trip was to Alabama Hills California that was amazing. The next was to Oregon Dunes National Recreation Area. On both trips Gladiator with new tires got incredible mileage and performed extremely well on and off-road. Alabama Hills was fire roads, Oregon Dunes was sand and more sand.
Airing Down - Side Lugs Put To Use
I aired down to between 18 and 20 psi going off-road. Tires spread out nicely and side lugs are in a position to add a lot of traction. 18 to 20 seems to be the sweet spot. This picture is from Hollister Hills SVRA the day we encountered Cybertrucks.
A Good Tire Recycling Story - A Buddy Was Happy To Get These Tires
Buying new tires usually results in the equal quantity of tires making a one way trip to the landfill. Tires like these Falkens and other slightly used tires are available in abundance on you favorite online market place. I was prepared to pay the recycling fee abandoning 5 -7000 mile Falken Wildpeaks at the tire shop. Tire shop guys had no use for them. I called a buddy. He installed them on his truck and the price was right, free. Tire dump was denied this rubber for at least a little while.
Would I Buy Nitto Tires Again When These Wear Out?
The Nittos have about 8000 miles on the road, 2 Overlanding trips, 1 mountain, 1 sand. Would I buy these Nitto Trail Grappler 35x10.5x7.5 tires again? Yes I would. Heres a short evaluation.
Great on the road, no death wobble, drive perfect.
MPGs are still very good on the Ecodiesel.
Awesome performace off-road when aired down.
Wearing evenly (I rotate them) and seem durable.
They look fantastic!
