I've run a decent amount of take-offs on the street. Personally, I think 
most of the pressures quoted are too low for the street, I always run 
38lb in the back tire and 33 front on the street, even on take offs. 
Your tire life is going to go up with the higher pressures. Never had 
any grip issues in the rear. I try to only run the fronts though for the 
warmer 6 months here in nor-cal, maybe this is where a lower pressure 
might help, but in the mornings, 50deg and below, the rubber just feels 
hard and the grip doesn't seem to be there. I guess thats the heat 
cycles at work.
