Drag Radial Tire Pressure

[LS6NickM]

Hey guys, im taking my car to moroso tommorow night for the test and tune night. The temps should be about 60-65. Im just wondering what ideal tire pressure for my Nitto 555r drag radials would be. They are 305/35/18s on stock size z06 wheels. Thanks in advance for any advice, and ill keep everyone updated on what I run. PS this is the first time with this car at the track

I originally started racing these at 18 PSI, but now I normally drop to 16.5 PSI . I ran Sunday with 14.5 to 15.5 PSI and pulled off my best 60' ever (1.618) with the Nitto 305/35/18. But my best trap was running at the 16.5 PSI. I'm checking pressure when the tires are lukewarm.

Last time on the track I ran 14 psi, then had it on 13 psi and felt better traction. good luck

14-16 psi and make sure you do a killer burnout. Nittos need heat!

Well from what you guys are telling me, I think ill start em around 17 and go down one pound after every pass. Ill let you know how it turns out. Thanks

My best to date was @ 18psi...
