常用的轮胎更换周期就是：5年或8万左右。您的轮胎需要更换了吗?具体要看车辆的行驶路况和轮胎的磨损情况，
济南沃尔沃汽车养护人员认为这几种情况就必须更换：
The commonly used tire replacement cycle is around 5 years or 80000 kilometers. Do your tires need to be replaced? Specifically, it depends on the driving conditions of the vehicle and the wear and tear of the tires. Jinan Volvo Car maintenance personnel believe that these situations require replacement:
1.当胎纹深度低于1.6毫米，也就是胎纹达到磨损标记极限;
When the depth of the tire tread is less than 1.6 millimeters, it means that the tire tread reaches the wear mark limit;
2.轮胎出现鼓包或变形，也就是胎壁内部达到损伤极限;
2. The tire has bulging or deformation, which means that the inner part of the tire wall has reached the limit of damage;
3.胎侧出现龟裂，也就是轮胎达到了老化极限;
3. Cracking occurs on the sidewall of the tire, indicating that the tire has reached its aging limit;
4.胎肩或胎侧被扎或被啃坏，也就是胎肩、胎侧达到损伤极限;
4. If the shoulder or sidewall of the tire is punctured or gnawed, that is, the shoulder or sidewall of the tire reaches the limit of damage;
5.胎面被扎4次及以上或被扎直径超4毫米，也就是胎面达到损伤极限;
5. If the tread is punctured 4 times or more, or if the diameter of the punctured tread exceeds 4 millimeters, it means that the tread has reached the limit of damage;
轮胎花纹磨损到规定极限(花纹深度为1.6MM)时必须更换轮胎磨损到使用极与地面的附着力下降,摩擦力变小,会出现行驶中打滑的现象,特别影响制动效果,并且高速行驶中极易爆胎冰雪路面制动发生跑偏,所有这些严重威胁着行车。
When the tire pattern is worn to the specified limit (with a depth of 1.6mm), it must be replaced. When the tire is worn to the limit of use, the adhesion to the ground decreases, the friction decreases, and there may be slipping during driving, which particularly affects the braking effect. Moreover, it is easy to have a tire burst during high-speed driving on ice and snow roads, leading to deviation during braking, all of which seriously threaten driving safety.
更换原装轮胎的重要性轮胎是车辆与地面直接接触的备件，对行车起到关重要的作用。原装轮胎抗磨损，抗老化能力强，胎噪低，质量有保证。
The importance of replacing original tires is that tires are the only spare parts of a vehicle that come into direct contact with the ground and play a crucial role in driving safety. The original tires have strong wear resistance, aging resistance, low tire noise and guaranteed quality.
外面市场上翻新轮胎较多，从外观上很难辨别，表面上看可能比4S店低一些，但劣质轮胎使用里程短，平均到每上一点都不便宜。重要的是，劣质轮胎在高温，高速情况下非常容易爆胎，是行车的一大隐患，甚会酿成车毁人亡的惨剧。
There are many refurbished tires on the outside market, which is difficult to distinguish from the appearance. On the surface, the price may be lower than that of 4S stores, but inferior tires have shorter mileage and average prices that are not cheap at all per kilometer. Importantly, low-quality tires are very prone to tire explosions under high temperatures and high-speed conditions, which is a major safety hazard for driving and can even lead to tragic accidents such as car damage and fatalities.
Now, friends, you know the importance of checking tires and replacing them in a timely manner. Do your tires need to be replaced? Conduct your own investigation based on the above content, or regularly check at the car repair service point according to the time.
