55mm Thickened Square Rod Improves Longitudinal Rigidity, Roadbuck Tire Changer Resists Heavy Load Deformation

Horizontal limit solves left-right offset, while longitudinal pull rod rigidity controls front-back shake of mounting heads. Ordinary thin rods bend under run-flat tire pressure, creating extra clearance and scratching alloy rims.

Roadbuck upgrades four-way pull rod to 55mm tempered high-strength steel, lifting longitudinal bearing capacity by 20%. The top cup cylinder locking structure fully fixes arms under standard 8kg air pressure without loosening. Every unit passes air tightness test before delivery.

When disassembling 17–24 inch stiff tires, longitudinal displacement of the mounting head is strictly restrained, protecting painted and forged wheel hubs from scratches. Roadbuck refuses material cost-cutting on load-bearing parts, combining horizontal and longitudinal reinforcement to guard tires and rims.
