2022 Jeep Gladiator Speedometer Calibration HELP

[Evan033]

So I recently bought a 2022 Jeep Gladiator Overland. I threw 35s on and also got it regeared to 4.56. However, I contacted rough country and they done have a speedometer calibrator for the 2022 model yet. Does anyone know of any or could give me tips on what to do?

Tazer mini can help and has other capabilities as well. Have not heard of any issues with 2022 models and tazer ... If your only concerns is tire size & gears .. the AEV pro cal will do the trick for less money ..

I used a sharpie and some tape to relabel the speedometer.

Is it that far off? Test it with a GPS/Phone.

I used a Tazer Mini on mine. Ditto what Jay said above. Find the exact size of your 35's...34.xx inches to be accurate. I have Copper STT's 34.71"
As for what David (Casique) asked. If you dont change it, the computer will throw a code as mismatch between trans and tire size ..... ask me how I know???

You have to change the gear ratio in the computer also. Tazer will work for that. Not even sure you should drive it without chnaging.

Jscan will allow you to change tire size, differential ratio and even add/subtract a % error to the speedometer.

And it’s much less expensive than a Tazer.

Yes, but Tazer offers much more and is constantly being updated with new features.

And the Tazer is much easier to use and does not require anything else besides the Tazer.

Tazer Mini is all you need to change tire size and gear ratio.

This should work just fine with a diesel JT?
