Drag Radial Question
 

What is the best pressure to run Drag radials at? I have 275x50x15. I am very unhappy with their perfomace last friday night--totally blew them away! I thought I did a good burnout like I was told since they were brand new but they did not hook at all. What size backspacing on your wheels do you have inorder to run this size tire? I have 5.5 and they rub on the inside. Hammer time?!?!

92 gt, ATI Procharger 9 Psi., P.A. C-4 w 3200 stall, 3:55's, Flowmaster Dumps, Cobra Intake, MSD,Al. Driveshaft, Jeg's Safety Loop, Griffin Al. Radiator, Stock Heads, Cam, Rockers, 12.5 @ 108 on street tires, much more on the way

Don't know about the backspacing, but run 10-15 psi in your tires at the track. A friend of mine went from 2.1 60's to 1.9's when he went from 25 to 12.
