What are the signs of tire aging?

The signs of tire aging are: 1. The appearance of many fine cracks, which not only affect the comfort level of the tire (quietness) but also cause a severe decline in the tire's grip performance; 2. If the tire feels much harder than before, it is highly likely due to tire aging, especially in hot weather; 3. Generally, the wear indicator height for passenger car tires is 1.6 millimeters, and for load-bearing tires, it is 2.4 millimeters. If the wear indicator is flush with the tread, it indicates that the tire is nearly worn out. Tires are circular elastic rubber products assembled on various vehicles or machinery to roll on the ground, usually mounted on metal rims. They support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance.

What is the method for managing oil burning without dismantling the engine?

The method for managing oil burning without dismantling the engine is: heating the cleaning agent while the piston moves up and down slightly, allowing the cleaning agent to penetrate deep into the piston rings for cleaning. The reason for oil burning is: after the engine has been running for a certain period, the width of the piston rings decreases, their elasticity weakens, and the gap between the rings increases, leading to more oil in the gaps. When the piston moves upward, the oil is scraped into the combustion chamber and burned along with the air-fuel mixture, resulting in oil burning. Oil burning in a vehicle can cause the oxygen sensor to fail prematurely, increase carbon deposits in the combustion chamber, lead to unstable idling, reduced acceleration, increased fuel consumption, and excessive exhaust emissions. In severe cases, it can result in insufficient engine lubrication, causing irreparable damage or even complete engine failure, significantly increasing repair costs and posing potential safety hazards.
