Tirerack online shows one 18” and lets you see what if looks like on the VX- check all years of the VX. Check also with Discount tire online but 18” are not going to be cheap. I recommend 17” wheels as you have a greater and cheaper selection of rubber. I am also checking with another vendor to see if he can offer us a wider selection of 18”s as they deal with imports and have access to some unusual wheels.
