How much can rear tire pressure affect acceleration? Whats a good rear tire/front tire PSI to run on the street that will help with those occasional stoplight "spirited launches" but won't kill handling? Thanks. Tryin to see if I could pick up a tenth of a second or so for free

Quick update, I checked my tire pressure all around. I'm at about 25 psi all around, the dealer sent it this way. What should I change it to from 25 psi in each to HELP acceleration. These are the stock tires on the 17" premium GT rims.

Most people lower their rear tire pressure to 25-28 PSI at the track. On the street I run 28-30 out back and 34 up front.

Ford recommend 30-32 psi, however, I'm going to run 24-25 once I get a set of DR
