The all new GPS Gravity 643 Mini Truck Tires are designed specifically for Mini Truck applications or vehicles with a higher payload. The GPS Gravity 643 tire is available in 6 ply or 12 ply. With multiple years of extensive testing we found the perfect rubber formulation that provides extreme wear life with unmatched durability you expect from GPS Tire. The GPS Gravity 643 makes a perfect offroad tire and performs well in rocky, muddy, sandy or hard pack offroad terrain. Not recommended for use on paved roads, with it’s open tread pattern the tire will be noisy and not wear well on pavement. The GPS Gravity 643 in the 12ply version offers a load rating of 849lbs at 12psi and was originally designed for the Japanese Mini trucks and for offroad use.
