Depends on tyre size, and offset. Do you want big diameter, or width? 17 is about the biggest diameter you can get without affecting the rolling radius too much (and therefore gearing/final drive + speedo). Width, 8" is ok at the front, you can get 10" under the rear with the right offset - and as long as axle x frame kit/exhaust ect doesn't get in the way.
