air pressures

[racin6mod]

looking for air pressure ideas for ump a's and d's. we have been running 9psi on the left and 12psi in the rr and 14 psi in the rf. the main reason I'm asking is in the photos our rf tire is rolling under a lot more than most we have softened the front springs and will be tring that set up out soon.

try 10lbs on left side 15lbs on right side.

Feature time is usually for us.
Lf- 10. Rf-15
Lr-9. Rr-13

10-14
9-13

lf 9 rf 12.5
lr 7.5 rr 12

There are several factors that dictate what pressures should be run: tire size, compound, location on car, temperatures after running a race, suspension type, track conditions, driver style, etc.... You will find many answers here. Start with 12psi on the left side tires and 15psi for the RF 13 for the right rear. CCheck pressures immediately after a race and get a tire pyrometer to check tire temps. Pressures and temperatures after racing can be used to find the optimum psi for your car.
