常用的輪胎更換周期就是：5年或8萬公里左右。您的輪胎需要更換了嗎?具體要看車輛的行駛路況和輪胎的磨損情況，
濟南沃爾沃汽車養護人員認為這幾種情況就必須更換：
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.當胎紋深度低于1.6毫米，也就是胎紋達到磨損標記極限;
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.輪胎出現鼓包或變形，也就是胎壁內部達到損傷極限;
2. The tire has bulging or deformation, which means that the inner part of the tire wall has reached the limit of damage;
3.胎側出現龜裂，也就是輪胎達到了老化極限;
3. Cracking occurs on the sidewall of the tire, indicating that the tire has reached its aging limit;
4.胎肩或胎側被扎或被啃壞，也就是胎肩、胎側達到損傷極限;
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次及以上或被扎直徑超4毫米，也就是胎面達到損傷極限;
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;
輪胎花紋磨損到規定極限(花紋深度為1.6MM)時必須更換輪胎磨損到使用極與地面的附著力下降,摩擦力變小,會出現行駛中打滑的現象,特別影響制動效果,并且高速行駛中極易爆胎冰雪路面制動發生跑偏,所有這些嚴重威脅著行車安全。
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.
更換原裝輪胎的重要性輪胎是車輛與地面直接接觸的備件，對行車安全起到至關重要的作用。原裝輪胎抗磨損，抗老化能力強，胎噪低，質量有保證。
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.
外面市場上翻新輪胎較多，從外觀上很難辨別，表面上看價格可能比4S店低一些，但劣質輪胎使用里程短，價格平均到每公里上一點都不便宜。重要的是，劣質輪胎在高溫，高速情況下非常容易爆胎，是行車安全的一大隱患，甚至會釀成車毀人亡的慘劇。
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.
