Rear wheel rim AD50 China is a wheel rim for Suzuki Address (AD50) scooters. The rim is the basis of the wheel, and the tire is mounted on it. The size in the name (diameter in inches and rim width) must match your wheel, and the brake type must match the hub.
Replacement is needed when the rim has cracks and dents, runout, or the tire does not hold air because the rim is deformed. It is best to keep the old part until the new one is installed, so you can compare the dimensions and the position of the holes.
