Largest rear tire on a 17x9

[zZsKyZz]

What is the largest tire I can fit on the rear of my stang with 17x9 rims? right now I have 245/45/17 but would like something a bit beefer that will make it have a meaner look from behind...what if i add spacers and such?

Thanks guys! :SNSign:

For most tire brands a 275/40R17 is reccomended. I know a lot of 03 cobra guys run 315 nitto drags on their stock 17x9 rims i am going to get a set of those on the back of mine soon hopefully.

IMO, there's no good reason to put 315's on a 9" rim. I would go with nothing larger than a 275/40.
