What tire pressures are/should you be running for Auto X?


Currently running Stock street tires 42/38psi (Front/Rear)

Depends on too many factors to be helpful.

Tires, surface, heat, how you drive, alignment, etc.

I tend to have more pressure in the rear than front though to help the car rotate better.

At least for me with a Bone stock suspension, and a dusty course when I tried to inflate the rear more the backend tended to oversteer alot to the point of spinning out. With 1 push of the SAWC button. What worked for me was about 37psi up front and 32-34psi rear.

But it really depends on the driver. It is too hard to judge otherwise. Just try a ton of different setups and see what works for many courses. Then you can adjust from baseline to match each condition.

^This.

When it was 45 degrees out, and in the stock yoko's, I ran 38 rear 37 front. I won pax that day. When it was 80 with the sun shining, and my tire gauge was giving me bad readings, I ran that same pressure with direzza's and was sucking it up big time. Then I tried another tire gauge, bumped it up to 48 rear, 46 front, and picked up two seconds from my best run.

That's not to give you any frame of reference as much as it is to give you an idea of how much the right pressure can vary. I prefer not to be below 44 psi in the summer though, too much tire roll.
