I need some help..I just started racing last yr in a 81 toy celica. I'm still alittle green but I'm trying to find out how you determine your tire pressure.Also do you change it from the heat when it's wet to the feature where it pretty much a dry slick.Have a lot more question but I'll start there.. Thanks

yes when it is wet or tacky you can run a few more pounds of air and when it is dry drop it down. what kind of tires are you running. Also once you get you pressures close you can get a cheap guage to measure heat in the tires you want to trya nd get it even all the way across. Check 3 different spots on the tire edges and center. I just got a cheap meat tempeture gauge from harbor freight. YOu just need to watch not to go to far in or it could cause air leaks. Just my .02 BObby

when I was running I would run 12-14.5 lf 20-22.5 rf 16-18 lr and 17-20 rr. That should get you close.

know what b4... I have always been told to run even pressure in the fronts... but a few weeks ago, i drove a friends back up car, and it pushed in the turns really bad, fast car though, so i though **what if** and I upped the RF like 5 more pounds than the LF and it turned great. I guess it has nothing to do with what the question was, just your comment reminded me of that night. but at our track we run way less pressure, do you run more than one track and have to adjust accordingly? Or would you run that pressure at whatever track you are at that night? I know I upped my pressure like 4 lbs all around one night as an experiment and I was all over the place. Just curious...

The thing I was always was told was one that radials built up 2 as much air if they were to low. And I also had noticed that with me setting higher pressures it made the tires not have so much roll and it made me stick and go to run these pressures. I also do not run tubes and have knocked tires down from running very much lower. So again this is just how I liked the feel of my car a different style of driving or a different set up might like it with less. To each his own BObby

that is what i was thinking since you are adding that much lr weight and taking weight off of the rf. I would try a smaller backspacingon the rr. or you might a pound or so less air in the rf. Just my .02 BObby
