Re: ET Drag tire pressure?? Try starting around 13-14psi. You don't want to go too much lower than that, because you can actually cause the tire to wrinkle too much, and actually start to run itself over, unloading the rear suspension and causing wheelspin...
Re: ET Drag tire pressure?? I run mine (28") at 16 and have had no traction problems. I'll prolly up it a little next time out. Keep in mind that I run at a well prepped track though, HRP.

Re: ET Drag tire pressure?? Keep in mind that a lot of it is going to come down to track prep, and just how violently your car hits the tires... As most anyone else will tell you, you'll want to run as much tire pressure as you can without sacrificing traction. Generally, a larger tire will usually require less pressure as well. You should see what guys with tubbed cars and big 33" tires run for pressure (6-8psi).
My car initially hits the tires very hard, hence the lower pressures I run.

Re: ET Drag tire pressure?? I usually run mine about 15-16 with good results. I will go a little lower though if the track is not hooking. If you have a 6-speed you may have better luck running them around 12 or so.

Re: ET Drag tire pressure?? You want to run as much as possible, otherwise the car is mess at top track, swaying and feels really sloppy.
At 11psi my 28x9x15 ET Drags felt really sloppy on the big end.
