18x9 front +42
18x10 rears +37

I am running TEIN FLEX coilovers. Will they fit and what size tire should I get?

 

aggh, this has been discussed so many times....

18x9 +42 will be pushing it but may be ok, depending on exact tire used and other suspension variables. Using a 245/40 instead of a 255/40 will give you a little more clearance.

18x10 +37 in rear will likely rub, you will have to roll your fender lips, running a 265/35 instead of a 285/30 may or may not give you more clearance.

 

I guess why I brought this up is that the local company that I am buying from said I could have some rubbing issues but would definately not need to roll my fenders

 

Hmm...I would be leary about a place that says you "could" have rubbing but would "definitely" not need to roll the fender lips. Seems a little contradictory to me.....

Picture an 18x10 +37 wheel -- It will stick a minimum of 38mm further out toward the fender than the stock wheel (probably more, due to actual wheel width vs. nominal wheel width). 38mm = 1-1/2 inches.

Unless you are getting an absolutely unbeatable deal, why don't you at least contact Rishie (ARD T2) for your wheels? Rishie is the forum wheel vendor and will give you a good deal and he knows what will fit on your car.

I would contact Rishie before pulling the trigger on these wheels.
