I just put on my 18" Ruff racing wheels and Ventus Sport tires. I am not sure what air pressure to run in them, after storage they have between 36-39 psi in each tire. The sidewall says max psi is 51.

I am used to running 30-32 in my 245 60 16s on stock rims.

How much air pressure should I run?

rims/tires front 245 40 18 tires, 18x9 rims
rear 275 35 18 tires, 18x10 rims

Thanks!

does the size of the tire make any difference in the air pressure you run?

Like more or less psi for a low profile, wider tire?

Thanks!

mark the tire with flour or fine sand and then take a short drive, should be able to see where the contact patch is on the tread...I start high and drop it until I get even patch across the tread, otherwise wide tires tend to wear the centers pretty bad

Thanks for the info. I ended up with 32 in front and 30 in the back and that seems to work great!! Rolling flat too!

Thanks again!
