With an 8inch wide rim im around 22-24 PSI. Do the chalk test start with where your tire pressure is now and continue to let air out after each test until you get good wear from the chalk. A lot of guys will run different tire pressure due to the weight they are carrying in their Jeeps. Right now im fairly light which is why i need to air down more to have a good wear

I have the same tire. I run 27 psi. Probably could drop 1-2 and still be good.

I run mine 26-28. Chalk tested them at that pressure and it had an awesome footprint.

Chalk tested the 35's when I ran them and 26 was good.

Now with the 37's chalked at 25.

Rides really good.

For some of the guys who are saying your tire pressure can you post your rim sizes as well? This could make a difference when it comes to what tire pressure you are running or am i wrong?
