Zhigu's alloy offroad wheels are built to conquer the harshest terrains, combining 6061-T6 forged aluminum with rugged engineering. Key off-road features: reinforced wheel barrels (3mm thicker than standard), double-walled construction for impact resistance, beadlock rings (12.9-grade bolts), and anti-corrosion coatings (zinc-nickel plating + powder coating). Offroad wheel designs include: 8-lug patterns for heavy-duty trucks, negative offsets (-15 to -40mm) for wider tracks, and rock guard lips to protect against trail damage. The wheels are tested in simulated off-road conditions: 500-hour salt spray testing, 10,000km rough road simulation, and tire deflation durability. Compatible with popular off-road tires (33"-37" sizes), these wheels support vehicles like Ford F-150 Raptor, Chevrolet Colorado ZR2, and Jeep Gladiator.
