It definitely depends on what you like, but like Zeus said, if you plan on wheeling, I would say 16"s also. As far as looks go, I personally like a nice balance between metal and meat. The 18"s push the bling factor a little to much for me, but that is easily solved with some black rims. But bigger than 18" is just way to much for me. A VX on rubber bands just does not look right, imho...
