I don’t know that the majority of riders mainly use unmodified wheels. The edge of the wheel hub (rim) is too thin and sharp? The sharp wheel rim can directly cut the tire when the car is driving at high speed, cornering, and passing obstacles. The impact force can cause accidents , This is not alarmist talk, we need to face up to these problems, so as to avoid accidents. First of all, let's understand what is tire cutting Tire cutting generally occurs when the outer edge of the wheel hub (rim) is relatively thin or the rim has not been polished and blunt. Through the impact, the rim and the tire are in contact to generate friction. According to the impact force, the rim can directly touch the sidewall of the tire. cut or severely worn. why cut the tire Most tires today come in the form of tubeless tires, and tire manufacturing starts on the inside and ends on the rim.
Due to the problem of use, the pattern of the tire is directly in contact with the ground, and the car will wear out when starting and braking. Therefore, the surface of the tire is usually more durable than other parts, but the contact point between the sidewall and the rim does not have the thickness of the tire surface, so the performance more fragile.
