Nah, they're 12 inch rims. I measured my rims and tires when they came in b/c the fronts looked different than the back. The fronts measured at 27" like they were supposed to, but the backs measured almost 28.25" or so. I know I coulda deflated them and lowered em down a bit, but I just left em for now.
I had to bend in the front fender supports with a mallet to keep the fronts from rubbing in hard turns, and on the back I had to trim a little off the edge of the fender. They still rub when I hit big dips at high speeds. Some of the guys use a heat gun on the fenders to flare them out a little so they don't rub. You might try that if you're looking to get away from the cutting. I just went ahead and did it the easy way. Good ole Dremel tool.
