Im looking at buying a set of volk te37's for my S, but im afraid the 7.5 sizing all around may be a problem. The wheels are 17x7.5 (all 4), and tires mounted are 225/40/17 (all 4).

Do you folks think I will have any trouble, rubbing etc. with these on my S?

 

First, what is the offset? Second, the rear tires are too narrow and the overall diameter is too small. The tires upfront may fit depending on the offset, but at the very least you would like larger tires on the rear. With a 7.5" wide rim you should be able to go w/ 245/40s which would be the appropriate size, but it all comes down to the offset.

 

^ What he said.
Rubbing depends on the offset of the wheel.

But you will want a wider tire in the rear to keep the stagger (under/over steering). They will work if the offsets are at least 48mm or so, but youll want to put wider tires on the rear eventually...
