I'm sure this will start many arguments...however I just changed from fuzion (which I thought was a crappy tire) to bridgestone potenzas. They seem to grip just a little better, but I need to take the same turns at the same irresponsible speed on the way to the tire place to really tell the difference. Now I got a good deal on the tires, they are brand new which is good for when I go north where inevidibly it will snow for my month-long xmas vacation, however I had a technical question. I do know that slightly softer springs on your ride will give more body roll, somother ride, and in SOME cases more raw lateral grip (but only if you REALLY know how to drive!), whereas firmer springs give a harsher ride, but crisper turn-in with less body roll, and often times its easier to control your car. I was wondering if the effects of slightly less or more air in your tires did the same thing--i kept my fuzion's high in the normal pressure band, and I had a little less roll from my car than with the bridgestone's which i haven't even checked my pressure on (just picked my car up an hour ago).
I'm just trying to see if the bridgestone's really have more grip, or if I just got ripped off.
