The invention discloses an anti-abrasion device. A right rear wheel becomes a spare wheel for standby. Tire bursting is a first killer in highway traffic accidents, especially in summer. According to statistics, 46% of the traffic accidents on expressways are caused by tire failures, wherein tire bursting accounts for 70% of the total tire accidents. As the saying goes, air pressure is the life of a tire, and high temperature is the main killer of the tire, tire bursting is mainly caused due to the fact that the air pressure of the tire is too low or too high, tire rubber aging can be caused by the high temperature generated in the high-speed driving process, fatigue strength is decreased, and abrasion of the tire surface is severe. Therefore, the key for preventing tire bursting and ensuring safety driving is to keep the tire pressure normal and stable. Due to the fact that compressed air is used for air inflation of general tires, the compressed air contains moisture and oil which can cause oxidation to the tire by combining oxygen in air, and aging of the tire and corrosion of a steel rim are accelerated, so that air leakage of an air cock and air permeation of the tire are caused, and the situation that the tire pressure is not stable is caused.
