I found some concave wheels am ready to buy. Most people go wide in the back small in the front, which leaves a bunch on concave in the back and none in the front. That looks weird to me. So am trying to run a 20x10.5 with +40mm offset in the front or a 19x10 with a +35mm offset preferably the 20s. Would they fit with an appropriate size tire or with some slight modifications?
