Hankook RS4 question. I was going to buy a set of RS4's but I don't see the size I always get. I have some 18" x 8.5" wheels with a 43 offset. I have to run 7mm spacers on the front due to my BBK. I usually get 235/40 R18's and they rub on my plastic wheel well liners.
The only thing I see close is 245/40ZR18 RS4. Do the Hankooks run a little narrow by any chance?
Have you done the fender screw mod? I had minor rubbing issues under hard compression on 245/40/18s, which was remedied by the fender screw mod.
FWIW, TireRack says a 235/40/18 Michelin PS4 is 8.3" wide vs a 245/40/18 R-S4 is 9.9" wide.
