Zhigu's offroad wheel rim is built to withstand harsh terrains, featuring a forged 6061-T6 aluminum barrel with a 5mm-thick wall and reinforced bead seat. The rim is designed to work with beadlock systems, providing tire security at low pressures. A proprietary RockShield finish combines a 200-micron powder coat with a 1mm-thick elastomeric layer, resisting impacts from 4" rocks at 25 mph. Internal stress-relief grooves reduce cracking risk by 45% during articulation. Available in sizes from 15-22 inches, these rims support tire sizes from 31-40 inches and have a load rating of 3,800 lbs per wheel. Tested in Moab, Baja, and the Rubicon Trail.
