When do tires generally need to be replaced?

When tires are severely worn, bulging, have exceeded a certain age limit, or when nails puncture the tire sidewalls, they need to be replaced. Failure to replace tires can lead to dangerous blowout situations while driving, especially at high speeds where blowouts can be particularly severe. Additionally, it is important to regularly clean small stones or sharp objects from the grooves of car tires. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high or low temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning properties.
When it comes to changing tires, I habitually glance at the tire condition before every drive, mainly checking three aspects to make a judgment. First is the tread depth—if it's almost worn flat, using a coin to test shallow grooves indicates danger. Second is checking for cracks or bulges, especially on the sidewalls which are prone to deformation under pressure. Third is estimating based on mileage—ordinary sedans generally last about 50,000 to 60,000 kilometers, but frequent driving on gravel roads may shorten this. Safety first! Delaying too long risks serious consequences like a blowout. My neighbor neglected this and had an accident on the highway, resulting in expensive repairs and physical harm. Also, avoid parking in direct sunlight to prevent accelerated aging.
I'm a frugal person who always tries to save money, so I pay special attention to cost-effectiveness when it comes to tire replacement. Besides checking for wear, the age of the tires is also crucial. Even if the tread is deep, tires older than five years from the manufacturing date should be checked for rubber brittleness. I've used calipers to measure the tread depth and firmly replace them when it falls below the legal limit of 1.6 mm. I remember once trying to save money by continuing to use old tires, and the result was terrifying skidding on a rainy day. Also, pay attention to wear uniformity—if one side is higher than the other, it indicates a problem with the car's balance or suspension that needs adjustment first. Regularly rotating the tires can extend their lifespan by tens of thousands of kilometers. High temperatures in summer and frequent long-distance driving accelerate wear, so don't overlook this point.
