Default How much air to run in 18" rims

I seen that for 17" should run 30-33 psi but what about 18".... when I bought a tire package it came with 41 in front for a 245/40 and 44 for a 275/35.. is that right or is it too high.. max is 51psi. thanksss

I usually run 32 psi. All the extra psi will do is make it ride rough as hell, wear out the centers of the tires and bend a rim easier.

my tires were also inflated to the 40-45psi range. IMO, thats way too much. I have always run 35psi in my tires. I have 275 and 295-35-18s right now with 35 psi in all of them.

Wheel size has nothing to do with air pressure requirements.

I run 30 psi in all passenger car tires, and 50 psi in truck tires.
