35" according to zautomotive:

"

2020 and newer vehicles have a tire size limit of 35″ after which the ParkSense will be disabled. This is a Dodge factory limit and there is currently no way to bypass it.

None that I've seen. Mathematically,

35" diameter = 3.1416 * 35 * 25.4 = 2,793 mm circumference

When I did mine for 35” tires I read that 2710 worked, but as soon as I did that the park sensors were disabled. I backed it down to 2700 and it worked. Seems like a lot of people have tried different numbers and get different results.

After you did the tire size did you do the other steps on resetting the abs and clearing the codes? I don't remember the specifics, but each time i changed the size getting it dialed in, I had to do another step and clear fault codes.

I did the process I found on YouTube the first time I did it. I then read that on the 22 you didn’t have to do all the steps just the size change, so I’m not really sure that it is all needed or not

It doesn't matter, nothing you can do will prevent it when going more than a 35" tire
