my best advice would be to run them normally on the street at 35-40psi more or less...also if you just have bolt on's you should have no problem whatsoever in a straight line with the BFG's they hook like crazy...but they wear out alil faster then others, oh yea and when u've had them for a while after they start to go bald in the middle, in the rain i suggest that you drive like a bitch (in other words carefulllly) or else u might end up doin a few donuts or havin the rear end come loose on u at random moments

.. if you have a wide enough wheel to support the tire, at the track i say drop it to about 15 psi because supposedly when heated thats when the BFG dRAG radial is really at its best. other than that have fun spankin people at red lights... oh and jus to throw it in there i beleive the Bfg's drags have supported 8 second passes in a supra and other cars....so as long as the streets dry, floor it
