What is the general consensus on tire pressures for the RE71 in STU?

I'm running the white car for the first time this weekend, have 18x11 wheels on it, 285 RE-71s.

Thanks for any input.

 

Feedback I received from PO

Air pressure- typical asphalt pressures were 31f/27r. Slightly higher for high grip surfaces, slightly lower for low grip or cold.

So I'll start with that tomorrow and see how things go from there.

 

Started at 32/27 and then went down to 31/27 to notch my fastest time yesterday.

Good start, but not as high on index as I would prefer.

 

What is your offset on the 18x11?

Also I assume you mean the 275/35/18?

Z1only is/was running the 71's I will try to see what psi he was experimenting with.

I ran Z1Only's RE71s Saturday at autox to try out before i buy his used set. I put them at 32/31 PSI. I'm running with 2° camber up front and 1.70° in the back.

Cut 1.5 seconds off a course I was struggling to break into the 38s on RS3s. I was only pushing the car at 75% b/c they weren't my tires (yet).

 

I'm running CS but the same tires. No camber for me . I was running 33 front and 31 rear with good results. I didn't try to go lower than that yet although according to roll over on the fronts, I could go lower.

 

I run 265/275s on 9.5" wheels at 31/30 psi. My camber should be -2.5º front, -2º rear.

 

I'm thinking of getting these tires for next season but my wheels are 18x8 front and 18x9 rear.

Do you guys think I should squeeze the 245/40 on the front and 275/35 rear or would I be better off going with the oem sizes of 225/45 front and 245/45 rear?

 

IMHO never go OEM

 

You are correct, I was mistakenly thinking of the size of the RS3s on the other set of wheels that came with the car.
