The tires on the large front wheels of wheelchairs with electric scooters are severely worn, commonly known as "tire chewing" or "tire eating". The severe tire wearing is due to the angle of the rear wheel, which is directly related to the angle between the rear wheel and the ground. Generally speaking, sports wheelchairs are designed with an included angle for stability, and are not perpendicular to the ground, commonly known as an external splay. This causes the weight of the wheelchair to be transferred to the tires during driving, and the side pressure of the tires is relatively heavy. Yes, the pressure is not completely distributed to the rim and the force is evenly distributed, which causes the tire to be severely squeezed. The rim cannot share the pressure, and the tire naturally wears too fast. The rear wheel is light when it is perpendicular to the ground, and the greater the figure-eight angle, the more serious it is!
