OJ skateboard wheels Dirt Tires Thunder Juice 78a Black 70mm
OJ Wheels Dirt Tires Thunder Juice 78A – Black – 70mm (Pack of 4)
Ready for on and off-road shenanigans.
OJ's Dirt Tires take the classic high-speed Thunder Juice shape and optimise it for true all-terrain capability — an extra-large 70mm wheel poured in a soft 78A urethane, engineered as an all-weather, high-performance wheel built to conquer whatever's underfoot. Deep, precision-engraved treads run across the contact patch, channelling away moisture, dirt, and debris for exceptional bite in both wet and dry conditions.
A wide, stable stance maximises horizontal traction when carving at high speeds, delivering a cloud-like ride over rugged, unpredictable terrain — from gravel paths to rough pavement and everything in between.
