More than likely, yes.
I had 17 inch wheels on mine with a 2.0" drop and I had to roll the fenders to prevent rubbing even when taking little turns.
It all depends on the tire width, ride height, and wheel offset. So, you may be able to fit 18s, but you need to find the right combination that wouldn't rub without rolling the fenders.
