Tire pressures -- starting point - new setup

danegrey · 03-31-2022, 11:46 AM

Hi,

Looking for advice on where to start with tire pressures on a new setup
[Falken AZENIS RT660 - 275/35 18
Wheels ENKEI RPF1 18X10.5 +15

Last year I was running 19 stagger,
I was running with aiming for pressures after the run of 35psi front and 33psi rear.

just looking if I need to change, because of a square setup now.

Thanks for the help..

34 to 36 is a good range to shoot for.

On the same size set-up I start at 25 psi with 200 utq compound tires.

Question: What tire psi are people starting with on slicks?
I ran 305-660-18 slicks square, for the first time this past
weekend, but with the softer sidewall, I wasn't sure if I should start
with a higher psi or not. I started with 27 psi all around, and while my
times were 2 seconds faster per lap, the set-up seemed really soft.
