clearance issues

i just bought a set of cobra r rims for my '85 stang GT and was wondering if they will fit without any modifications. the rims are 17X9.my main concern is the fact that they look pretty wide. i haven't bought tires yet but plan to run 245/45/17's all around..............thanks
 
Might have to trim a little on the inner fender. I have 03 Cobra style wheels on mine and had to add 1 1/4" spacers. Mine was actually rubbing on the A Arm. My adise to you is to go with a 250/40 R17. I am running Falken B451's at a 245/40 R17 and they seem a little narrow for the 9" wheel.
 
agreed, the only problem u would have is the quads. ur might not have them. just check and see. if u have them u will have to flip them to get the room u need. if i was u i would put 245/40/17 in front ans 255/40/17 out back. i think if u have wider tire in back then u do the front it will look better IMO. but go with what u like, its ur car!
