Right now I Usually don't mess with my tire psi's. I run 16rf 15lf 14lf 13lr. No bead lock. I run American racer g60s. Am I in the ball park? Witch way should I go on the psi's on te tires to adjust for a rough track, smooth, ect. How to loosen the car tighten it up in the main ect.

Usually the problem with AR's is getting enough stagger out of 'em to get the thing to turn. You can gain stagger on the RR by putting about 40psi in it and setting it out in the sun the day of the race. Also, grind 'em!!!!!!!!!!!! Makes a world of difference on a heat cycled tire.

As for air pressure you are right on. I don't run anymore than 15 or less than 10. Definitely wouldn't run less than 15 with no beadlock. As for tuning.....the more air it has the more spring rate it has so on a rough track more air may not be better but you may need to run enough to keep it on the rim.

All these people have good advice.If you want to know what "your" car wants for t press. Just get a temp gage and check tire temps. Take three readings inside to outside just after the feature on each tire. steve smith has a tire temp program for the computer that is real nice. tire temps have tons of info!!! good luck.
