    Nitto NT01 tire pressure?

    I am wondering what tire pressure everyone is running in their nt01's. I picked up a set for my track wheels and I have a track day next Sunday.

    Look for 37-40 PSI hot. See what feels best for you. I like them around 38 front and 39 rear at Willow springs but was trying to keep them even at California Speedway this past weekend, around 38 hot.

    38 or 39 worked best for me, they drop off quickly over 40psi, at 44 it gets really fun, but slow.

    I'm running 33 Front & 37 rear and the car seems to really stick in the corners at these pressures. I tried higher PSI but the car felt very loose (understeer) in the corners. The temp of the track will also make a difference so each location may require difference PSI settings.

    Agree with above . . .

    Around 38 hot seems to work well with mine, you can definitely tell when the rears go over 40 as it will get very loose. I'm starting with cold pressures of about 28-29 in the Rear and 30-31 in the fronts.

    A car that is "loose" is oversteering, not understeering.
    Understeer is described as "push" or "tight."

    Yes, I agree.

    My car would understeer and "push/understeer" entering the corners and the tail would step out "loose/oversteer" coming out of the corners if I got on the gas to hard. Dropping the PSI to 33F/ 37R seem to make the car nuetral.
