I switched to 225/50/15 BFG DR's last year and had some trouble with them hitting my fenders. Towards the end of the year I put regular tires back on the Rotas I was using and put the BFG's on a pair of 02 Civic steelies. With the tires on the steelies the tires tucked under the fender and didn't rub. So what I'm looking for is the offset of the Rotas (15" Sub Zeros) and the offset of the stock 02 Civic 15" steelies.
