i run about 28 on the street and the same at the track. i used to run about 18 at the track but it was slowing me down on the big end at the track so i slowly kept adding more air till i got to about 26-28 at the track and i hooks just as good as long at there heated up good.most guys run lower psi but my car has some rear suspention work so maybe it hooks a little better that a stock suspention car. plus if you run to much the centers will wear out faster and to less will wear the out side so about 28 works good for me.
