Default What tire pressure you guys run in your ET Streets ?

Hey Guys,
I just bought a set of 275/50/15's M/T ET Street Radials mounted on set of Summit Stars and I was wondering how much tire pressure do you guys drag race with ? My mods are in my sig . Thanks in advance .

Same here about 16-20psi cutting 1.6 60". I ran an 11.91 at 114 on ZR1's and if you can get your 60 ft down you should be hauling even more. Good luck. P.S. I love my MT's I have put over 3k miles on them and still look brand new and they have been on my car for almost 2 yrs. Maybe I got an awesome batch but I doubt it.

Start at around 16 psi and work your way up until your car starts to not hook well and then step it back down. You want the most psi you can get w/ the car still hooking.

+1

Thats the way to do it IMHO I think around 22 psi as that was my best run. You will get a better mph with more psi so if it hooks keep adding it. Carrying a small amount of wheelspin off the line doesn't hurt em either as long as your not blowing them off.

cheers
