Max tire size on 9x18 rear wheel

[woodsman]

1.1% the wrong way--decrease in overall gearing and increase in weight. 255 is win/win but no doubt 275 looks better. I ran 225 all the way around for 4 months and the only real difference was looks and the car was noticeably quicker. I think the 's' is overtired from the factory in order to keep people on the roads including the degree of stagger front to back. Sometimes less is more but no doubt bigger looks better.

Like I said 1.1% your not going to notice and since this is a daily driver it could offset the weight with lower RPM's and better gas mileage during my commute to work, which is 90% highway.

My car has 255's on the rear for the summer and there's just not enough grip for me. The rear end comes out too many times running my favorite twisties with those tires, which are Dunlop Direzza DZ101. I'm going with Michelin Pilot Super Sport tires and lighter OZ Alleggerita HLTwheels, think I'll be just fine with that combo.

If you didn't notice a difference in cornering capability with 225's, you're not driving hard enough to care. I could feel the difference in balance just going up 10 mm on the fronts. Wider tires will benefit cornering grip, with a minor detriment to acceleration.
