dry track typically
LF 10, RF 14
LR 9, RR12

If its real tacky and/or rough we'll bump the right sides up 2-4# to keep from rolling the tire under so bad and to try and get the tire to slide over the ruts instead of digging in.

why so soft on the rr? they work better when your riding on the tread, not the sidewall.with an American Racer you want to stay above 9 psi.The softest i ever go on the right side tires is 12 psi. Any softer and your gonna be on the sidewall. Soft pressures are just a crutch for an ill handling car.

My opinion, these tires are roughly the same size as a pass. car would you run 9lbs of air on your outside tire and hit the on ramp at 60 mph.... good luck do you guys groove your sidewalls and put long studs on your bead lock?? LF 12 RF 15

LR 10 RR 17
AND ON ROUGH TACKY TRACK YOU SHOULD BUMP UP PRESSURE ON OUTSIDE TIRE'S A LEAST 4-5 lbs so that when you hit a rut your car will hopefully glide or skip over the rut. With low pressures the tires fold under and car shoots to the right. just my #45 cents of true info.GOOD LUCK GUYS ,BRAD
