Take your longboard or cruiser setup off the beaten path with the OJ Wheels Dirt Tires Thunder Juice 78a 70mm. Molded in a massive 70mm chassis, these heavy-duty cruiser wheels take the classic high-speed Thunder Juice shape and optimize it for true all-terrain capabilities. They feature a blacked-out colorway paired with classic bold OJ branding on the sidewall.

The standout feature of the Dirt Tires variant is the specialized, performance-driven surface texturing:

• Engraved Treads: Features deep, precision-engraved tread grooves across the contact patch. This aggressive pattern channels away moisture, dirt, and fine debris, providing exceptional bite in wet or dry conditions.

• Wide, Stable Stance: Built with a beefy 41mm overall width and a stable 25.5mm road surface that maximizes horizontal traction when carving at high speeds.

Poured from an ultra-soft 78a durometer premium urethane formula, these wheels deliver a cloud-like ride over rugged environments. They easily float over severe sidewalk cracks, thick gravel, dirt trails, and rough pavement that would instantly stop standard wheels.

At a substantial 70mm diameter, they boast massive top-end roll speed and exceptional momentum retention over long distances. The interior is cored with a rigid, high-grade plastic hub to maintain perfect bearing seating, preventing any sluggish or “squishy” response during sharp, high-speed carves. Note: Due to the tall 70mm profile, thick riser pads (1/4″ to 1/2″) and longer hardware are highly recommended to prevent wheel bite.
