Im going to put a smaller tire on it this winter tho.

I may not be up to the stats of the last few posts but I have 28 x 10 Et Drags with tubes on my 3400 Pound Dart Swinger. Runs 11.30's. I am up to 16 1/2 psi during the last test runs in October and got the best 60ft and best MPH.

My wife gets mad but I do little burnouts in my shop(facing out the door just in case) but it lets me see my contact patch on the cement. If its real dark on the edges of the black marks I know I don't have enough air and so on. It just helps me get close before I go to the track. When we go to Ennis we usually have to ad 1/2 to 1 psi to eliminate the tire squaring up. Each track may take a little different psi also.

I also agree with Bj, play with the pressure going higher and higher in small increments till its loses traction and then back off to where it got the most bite, personally my 14x32's likes anywhere between 7 to 8.5, only time I run more than that I'm trailoring the car.
Goodluck, Cp

I run 5 3/4lb-6lb psi. Depending on how much my car bites I will adjust Tire pressure. If it has to much bite or hooking to hard I will lower the Air Pressure or Wheelie Bars. If I am spinning I will raise the air pressure or wheelie bars to get some bite back in the car. 2450lb Monte Carlo running 4.70s-5.30 classes. 16x16x33.5 beadlocks M/T This will be my last set of M/t I ever own though. Going back to my goodyears. If my car feels unstable, normally its a shock adjustment and not the Tires being to low.

I tried the cement burn out, it does not work..... Here is how you do it.. You race and look at the tire, when the rubber starts to roll over the edges you are under inflated, so you play with it until you are at the point where it is edge to edge with out a noticible roll over at the edge
