yup 91rs is correct. Whats on the tire is the max psi..also keep in mind your psi will change according to temps too. So 50psi in 70degrees can turn into 55psi in 100 degree weather.

Go with 40 psi HOT and then work down from there. When I say HOT I mean after a nice canyon run, not just freeway driving etc. A lot depends on the balance and tire and rims size. There are several posts regarding this info. Use the search feature for pretty much anything here and you'll find your answers-

I found the stock recommended 37 psi in the 265's wore down the middle too fast also I am running 34 psi in the rear and 33 psi in the 235's up front, giving very good even tire wear.

Also I guess I don't rub because I am running stock height suspension.

right now i'm running 40 on my ps2's. 245's in the back and 225's up front. it should be fine, it's been cold.

91RS

The pressures listed on the sticker are cold pressures, so when you drive the car the tires heat up and the pressure gets higher. You will wear out the center of your tires.

Hello guys, what size of slicks do you would recomend for a C55?. I run 1/8 here in Paraguay and the track condition is very poor. I need a good rear slicks to stop spining...

Floored it at 10mph today with my 265/35/18 ps2's on Forgestars and the front end just lifted and took off, I dont think it broke traction at all Not bad so far, Car does rub on left rear side on highway dips. Will see if I can fix that issue somehow
