Whether it is a manual wheelchair or an electric wheelchair, wheels are a consumable item. When a wheelchair is used for too long, the degree of wear and tear on the wheels increases. When the grain on the wheels is smoothed by the road, the grip between the wheels and the ground is reduced, which can lead to wheelchair braking when going downhill, posing certain safety risks. If you are a long-term wheelchair user, you need to replace and maintain the wheels on a regular basis.
