This upcoming weekend is my first track event on Hoosier R6 tires. What tire pressures should I use with these tires? I have a degree and 1/2 negative camber in the front tires and 3/4 for the rears.

Any other recommendations for someone new to track tires in terms of what to watch out for.

if you run them hard the will cord fast on the outside edges

cold 33 frt 31 rear to start should end 40+- when hot if run hard.

Hoosier web site has good info give it a read

Thanks for the info

I felt like I was on ice on higher pressures 295F 335R I use nitrogen to fill the tires and only gained about 4 psi at the hot pit and 175 degree tire temps. I end up with 35F and 33 R

With IRS and proper geometry up front, tire pressures can be reduced from the recommendations listed above. When there is adequate camber gain and good roll control, the Hoosier radial tire will perform very well at the reduced air pressure. This results in a bigger "sweet spot" and easier control at the limit.

When tuning at reduced pressures use the following formula to determine the minimum safe pressure: Divide the total vehicle weight, including fuel and driver, by 100 to arrive at the minimum safe pressure. Example: Your car weighs 2750 lbs. as raced. The minimum safe (cold) pressure is 27.5 psi.
