什么样的情况轮胎才要换？轮胎磨损严重的、老化严重普遍出现裂纹的、频繁补胎的、起包变形轮胎内部的金属线圈已经变形或断裂、胎壁被扎等这几种情况都是需要赶紧换胎了。下面

What kind of situation does a tire need to be changed? Severe tire wear, severe aging, widespread cracking, frequent tire repairs, deformation of the inner metal coil of the tire, and punctured tire walls are all situations that require quick tire replacement. Below is an analysis from a BMW repair manufacturer in Jinan:
01
01
根据使用年限更换
Replace according to service life
轮胎的使用寿命一般为5年左右，达到这个时间一般就会出现老化、龟裂的情况，所以时间是一个很重要的参考值。我们在购买轮胎的时候一定要注意看清楚这几个数字，避免买到库存积压产品，也避免买到翻新轮胎。
The service life of tires is generally around 5 years, and aging and cracking usually occur at this time, so time is a very important reference value. When purchasing tires, we must pay attention to these numbers to avoid buying overstocked products and refurbished tires.

根据磨损极限更换
Replace according to wear limit
轮胎每年都和路面接触，就像我们的鞋子一样，是有磨损的。轮胎的胎纹沟槽里都有极限磨损标记，如果磨损到临近标记，那就需要更换了。胎纹磨损严重的轮胎，无论是抓地力还是排水性都会很差，继续使用会有很大的隐患。
Tires come into contact with the road every year, just like our shoes, there is wear and tear. There are extreme wear marks in the tread grooves of the tires, and if the wear reaches the adjacent mark, it needs to be replaced. Tires with severe tread wear and tear will have poor grip and drainage, posing significant safety hazards if used continuously.

根据老化情况更换
Replace according to aging conditions
因为每个人的用车环境不同，有的车可能没到使用年限或者数，但因为风吹日晒雨淋，加上保养不妥当，老化得也比别人的快。就像这样的轮胎，明显已经是严重老化了，我们用起来也不安心，所以还是要尽快更换。
Because everyone's driving environment is different, some cars may not have reached their service life or mileage, but due to wind, sun, rain, and improper maintenance, they age faster than others. Tyres like this are clearly severely aged and we are not comfortable using them, so we still need to replace them as soon as possible.

根据受损程度更换
Replace according to the degree of damage
正常行驶的轮胎，只会出现正常的磨损，但是路面情况复杂，轮胎的使用环境远比我们想象的残酷。如果轮胎撞击了坑洞或者碾压了大石头，都容易造成轮圈或者胎壁受损，导致轮胎产生鼓包。一旦轮胎出现了鼓包，说明轮胎内部的金属线已经断裂，这个轮胎就不能再使用了，因为易发生爆胎。
Normally driven tires will only experience normal wear and tear, but the road conditions are complex and the tire usage environment is far more harsh than we imagine. If the tire hits a pit or runs over a large stone, it can easily cause damage to the wheel rim or tire wall, leading to tire bulging. Once a bulge appears on the tire, it indicates that the metal wires inside the tire have broken, and the tire cannot be used anymore because it is prone to a tire blowout.
除了发生鼓包，轮胎另外一种严重损伤就是出现裂纹。这种裂纹有可能是因为橡胶硬化导致的，也有可能被石头割的，或者被人为损坏的。无论是哪种原因导致的裂纹，这些损伤都和鼓包一样，是无法修复的，只能选择更换。
In addition to bulging, another serious damage to the tire is the appearance of cracks. This type of crack may be caused by rubber hardening, or it may be cut by stones or damaged by humans. Regardless of the cause of the crack, these damages, like bulging, cannot be repaired and can only be replaced.
What if a tire has been repaired multiple times? Will it affect driving safety? A tire that has been repaired multiple times will definitely affect its performance, but there is no specific standard for how many times a tire can be repaired, as the size of each repair hole varies.
