什么樣的情況輪胎才要換？輪胎磨損嚴重的、老化嚴重普遍出現裂紋的、頻繁補胎的、起包變形輪胎內部的金屬線圈已經變形或斷裂、胎壁被扎等這幾種情況都是需要趕緊換胎了。下面濟南哪里有寶馬汽車維修的廠家為您分析：

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:

根據使用年限更換

Replace according to service life

輪胎的使用壽命一般為5年左右，達到這個時間一般就會出現老化、龜裂的情況，所以時間是一個很重要的參考值。我們在購買輪胎的時候一定要注意看清楚這幾個數字，避免買到庫存積壓產品，也避免買到翻新輪胎。

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.

根據磨損極限更換

Replace according to wear limit

輪胎每年都和路面接觸，就像我們的鞋子一樣，是有磨損的。輪胎的胎紋溝槽里都有極限磨損標記，如果磨損到臨近標記，那就需要更換了。胎紋磨損嚴重的輪胎，無論是抓地力還是排水性都會很差，繼續使用會有很大的安全隱患。

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.

根據老化情況更換

Replace according to aging conditions

因為每個人的用車環境不同，有的車可能沒到使用年限或者公里數，但因為風吹日曬雨淋，加上保養不妥當，老化得也比別人的快。就像這樣的輪胎，明顯已經是嚴重老化了，我們用起來也不安心，所以還是要盡快更換。

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.

根據受損程度更換

Replace according to the degree of damage

正常行駛的輪胎，只會出現正常的磨損，但是路面情況復雜，輪胎的使用環境遠比我們想象的殘酷。如果輪胎撞擊了坑洞或者碾壓了大石頭，都容易造成輪圈或者胎壁受損，導致輪胎產生鼓包。一旦輪胎出現了鼓包，說明輪胎內部的金屬線已經斷裂，這個輪胎就不能再使用了，因為易發生爆胎。

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.

除了發生鼓包，輪胎另外一種嚴重損傷就是出現裂紋。這種裂紋有可能是因為橡膠硬化導致的，也有可能被石頭割的，或者被人為損壞的。無論是哪種原因導致的裂紋，這些損傷都和鼓包一樣，是無法修復的，只能選擇更換。

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.

那如果一條輪胎被修補了多次呢？會不會影響到行車安全？多次修補的輪胎肯定會影響性能的，但是一條胎能修補多少次是沒有具體標準的，因為每次的修補孔洞大小不一樣。更多相關事項就來我們網站http://www.junwumy.com咨詢！

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.
