Lets steal an ege out of the fridge.Put it on the table w the pointed side down.That's about the shape of the cross section of a 150/60-17 on our 3.5" rear rim touching the tarmac.Lean the ege a little to one side.There is almost same footprint as w it's streight.Now lean it further to about 45' and suddenly you are approachingon the area where the foodprint is enlarging.This is the critical area.It's where the tire become unstable between low and high grip.metbandit1 said:there would be a larger drag area so it might affect your top speed but i dont think it would affect you handeling that much...might make it worse because of the larget tire to lean on to. but i dunno, eric?
You will be better of with a 150/70-17.Reasoned above.haha a 250! said:oh then i think i made up my mind im gonna get 150/60-17 but wat brand of tire for the street and the track?
