Drag Racing Tech - Air Pressure in 315/35/17 nittos?

I was wondering what the best pressure would be to run 315/35/17 nitto drag radials on 17x11 wheels? Thanks

I have them on 17x9.5 wheels and I pull low 1.7's on a 6 spd car with 19 lbs of air.

17psi Track - 25psi Street

Peace
Ever

I am ran 16.5 psi. last time out and left at 5,000 RPM with almost a dead hook, but only managed a 1.88 60’ my best so far.
I am still trying to dial-in the Hals. In the past, when I would get tire spin I would lower the pressure to 15psi and it would hook better.
I am also running on 11’ rims.

My brother 245- 50-16 work best at 13psi
Hope this helps

~20-23 when hot (check after each of the first few runs as it will climb and need to be bled.)

Also, it depends on the width of the rim to a small degree. With a narrower rim you'll need to lower the pressure more than with a wider rim.

Lastly, never run less pressure than is needed to hook...but you're best to err on the side of too little rather than too much. :thumb:
