Ordering the same kit as well! According to Jsport, they found that 255/60R18 has no rub issues whatsoever with a 35mm offset 18" wheel.Going to do the Jsport leveling kit. I ride a lot of backwoods roads in AK but will also use as a commuter. Looking at 18s. Will need lots of traction and ground clearance. Probably going to go with Hancook I Pikes maybe studded. What size will be optimal?
