Tire pressure question?

[SloRegal]

I have a set of 275/60/15 on 15 x 8 draglites. I was wondering at what tire pressure should I launch at and what #'s of boost. I have air bags and south side supension. What 60fter should I expect. Thanks Carlos

On my first GN with those tires mine would go 1.81 60ft with about 24 lbs of air!

What lbs of boost did you leave at? I dont want to roast tires. Thanks Carlos

Are those Drag radials or regular radials? You should be able to run 16-20 psi and still have an acceptable contact patch (no cupping) with that wheel/tire combo.

Opps forgot to mention that. They are Drag Radials.

I was running street radials and would leave at 2 to 5 lbs depending on track conditions!
