i still have the stock 17x8 rims on my mustang gt but i'm looking at hypercoated bullits for my next set. i'm putting 315s on a 10.5 in the back and american muscle only sells the fronts in 17x9 which wouldn't be a problem but i have fairly new tires on the stock rims and would like to use them. will a 245 fit comfortably on a 17x9? i know they recommend 275s for them.
