Well i just ordered some BFG drag radials, 315/30/18, for my 18x10.5" ZO6 wheels. And i have a few questions.

1. What PSI are you guys running in them for just daily driveing, so they waer normally?

2. What PSI are you running in them for launching on the street, concrete mostly?

3. And what PSI are you running at the track, and what 60' times are you getting?

Also im running 275/35/18 BFG KWD's up front, what PSI should those be in the same conditions. Should i just pump them up more at the track, if so how much.

After trying many combos, I ran 22 PSi hot on Goodyear F1-DS 245/50/16 and put down a 2.012 '60 with my old T/A. Ran 42 cold on the street.

I used to run 275 40 17 BFG DRs and aired them down the 17-19 at the track, 25 on the street. You'll find that its very hard to hook with 17s or 18s because there is very little sidewall to flex to help your launch...I hook way harder now that I've switched to a 16" wheel...Used to get high 1.6s to 1.7s with the 17s and was very inconsistent..Now I'm consistent 1.55 to 1.57 all day long...

So what are you guys running on the street to get good wear. Im trying to get maximum milage out of these things. I think the shop has them at about 35 now.
