Its a heavy 69 nova with bbc 3500lbs tires are on a 10" wheel. I know most people are saying to start at 16 psi but what will you get max traction at with a heave car?

16 PSI is a good starting point, then work from there in 1 PSI increments.

Thanks,

work your way up correct?

i'm running a 295/65-15 on my lightning at 18 psi currently. I'm having traction problems and am getting tire pressure recommendations as high as 21 and as low as 12.5. both guys making the recommendations have made them work and gone fast (7-8 sec 1/4 mile vehicles).

I run the 295-65, but my car is heavy too...3800#. My best 60 foot so far (1.32) was at 20.5 psi, but it'll hook hard from 17-20 psi.
I started at 17 psi, but kept getting faster as I added pressure. The track needs to be good to hold it at 20 psi though. Your results may vary.:cool:

will they actually get better traction with more air pressure? I started at 14 psi and they didn't seem to work that great. 295/55-15 i used to run regular et streets at 14 and they worked great. do you get better traction with the old et street tires?
