Just got a set of 205 50 15 Kumho's Can anyone give me a good psi starting point for auto-x? Except for a rear sway bar, the car has no suspension mods.

Thanks,
Russ

 

I have a set of MXs for the street. Mixed feelings about them (noisy), but they are fairly soft. The sidewalls are fairly stiff, so you don't need huge pressure increases.

I'd try 35-36 lbs at both ends of the car, and then fiddle with higher rear pressures depending on how you want the car to rotate/handle transitions. Your driving style may dictate this as much as anything.
