Since this is the page where i found myself while searching for wheel fitment, i will add the ones im looking to replace too.
Fenders arent rolled, so in big bumps they touch the tire (tires could be narrower). no any adjustable arms, so the camper is what it is (dont know).
Wheels: 5ZIGEN Fireball
Front: 18x9.5 ET12 - 245/40
