What is the max tire pressure I can run in my Hoosier front runners?

I usually run 40psi. They still look like a radial with a bulge/flat spot at that tire pressure. I want to bring it up as much as possible for a faster rollout.

I am trying every little tweak I can to get my 11 this weekend.

Thanks,

Ken

 

The most that I ever run is 45 psi. Watch out for red lights! (Your reaction times will be faster).

Good Luck,
