Default kumho V710 Psi for autox???

I'm running 315/35/17 fronts on 17x10 wheels 315/35/17 rears on 17x11's. I ran them last weekend at 28psi front and 26psi rear. I started them there cold and just bled them back off to those pressures after every run.

What pressures would you guys try? These things don't have alot of life left in them, but I would like to use them till I can afford a set of A6's

I run 28 psi F and 24 R with 315s and 335s on 17x11" wheels. I keep it there between runs. This is with -2.2 F and -1.4 R camber and on very grippy concrete.

On the F, I've tried up to 30 and down to 26. I've been as low as 20 in the R and as high as 28. None of these worked as well.

For the most part cold and maintained and checked before runs which right after they have climbed if i have shorter runs then i drop it lower. most of our runs here are on asphalt and about 68-90 sec long.

when i've gone to ones that are shorter i usually drop the pressure more

How do the 335's fit on the 11" wheels? I have considered going to them on the rear. I'm just worried they are to wide for the 17x11's

They're fine. Set at 24 psi they roll to the very edge. There aren't any mounting issues either.

Here's the F (315 on 17x11):



and here's the R (335 on 17x11):



and one more view of the R:



Photos were taken before I added COs and lowered the car.
