I'm new to mustangs, just bought my first one last week. it's an 01 GT. I need to get new tires and want to know what size to get. Thetires on it now are 245/45/17 I believe. The wheels are 17x8 or 17x8.5 i'm not sure but I think they're known as the bullit style wheels and are what came stock on the car. What is the widest tire that car be ran on these wheels and look decent? 265/40/17? 275/40/17? i'm also lowered -2.5" front and -2.3" rear. Thanks

 

on a stock 17x8 wheel, you should not run a tire thats any wider than a 245/45/17 or a 255/45/17.

If you get a nice set of aftermarket wheels like mine (which can be seen in my album) you can run 275/40/17's in front and 315/35/17's in back
