低胎壓爆胎幾率為何是高胎壓的2倍？

Why is the probability of a low tire pressure blowout twice that of a high tire pressure?

胎壓過低，與地面接觸的面積會變大，一方面會使輪胎和地面的摩擦系數加大，另一方面會造成輪胎滾動到下方時，胎側橡膠簾布中的簾線受壓變形過大，當輪胎滾動到上方，簾線在彈性和張力的作用下又要恢復原位，這會使內部的簾布層變形、加速疲勞，嚴重時造成結構性損傷。

If the tire pressure is too low, the area in contact with the ground will increase. On the one hand, it will increase the friction coefficient between the tire and the ground. On the other hand, it will cause excessive compression deformation of the cord in the rubber cord on the sidewall when the tire rolls below. When the tire rolls above, the cord will return to its original position under the action of elasticity and tension, which will cause deformation of the internal cord layer, accelerate fatigue, and in severe cases, cause structural damage.

這種反復的變形，濟南哪里修奧迪比較專業人員說的直白一點說就是車主們小時候都玩過用手掰鐵絲，鐵絲在反復掰動后會發熱，強度也會變軟，更容易折斷，輪胎內簾布層的胎體簾線也是這個道理。行駛時輪胎溫度更高，會加速輪胎內簾布層的胎體簾線變形，輪胎結構出現不可逆的損傷，繃不住就爆了。

This kind of repeated deformation, which is more straightforward than Audi repair in Jinan. To put it bluntly, car owners used to use their hands to break iron wire when they were young. After repeatedly breaking the wire, it would heat up, soften its strength, and be easier to break. This is also true for the tire inner cord layer of the tire body. When driving, the tire temperature is higher, which will accelerate the deformation of the tire's inner cord layer, causing irreversible damage to the tire structure and causing it to burst if it cannot be stretched.

胎壓高時，整體剛性增強，雖然不會出現摩擦過熱和過度屈曲，但遇到嚴重顛簸、高溫、尖銳物體碰撞時也會出現鼓包或者爆胎的情況。如果只考慮正常駕駛因素，高速行駛的情況下胎壓低無疑更容易引起爆胎！

When the tire pressure is high, the overall rigidity is enhanced. Although there will be no friction overheating and excessive buckling, severe bumps, high temperatures, or sharp object collisions can also cause bulging or tire blowout. If only normal driving factors are considered, low tire pressure during high-speed driving is undoubtedly more likely to cause a tire blowout!

胎壓不合適影響輪胎的壽命?

Does improper tire pressure affect the lifespan of tires?

通常輪胎標準充氣壓力2.2—2.8bar之間（冷胎壓）正確輪胎充氣壓力。空載情況下，普通轎車一般是2.3bar左右，越野胎是2.5bar。胎壓過高或者過低都會引起輪胎壽命縮短。

Usually, the standard inflation pressure of a tire is between 2.2-2.8 bar (cold tire pressure), which is the correct tire inflation pressure. Under no-load conditions, the average pressure for a regular sedan is generally around 2.3 bar, while for off-road tires, it is 2.5 bar. High or low tire pressure can cause a shortened tire life.

高胎壓：如果輪胎氣壓過高，輪胎的剛性增大，變形和接地面積減小，首先會導致使胎面中部的單位壓力增大，磨損加劇，產生胎冠磨損現象，影響到舒適性并將降低輪胎壽；同時，還會使輪胎抓地力減少(尤其在濕滑路面，會影響制動距離)，也會造成輪胎的磨損速加快，導致輪胎磨損不均勻。

High tire pressure: If the tire pressure is too high, the rigidity of the tire increases, deformation, and ground contact area decreases. Firstly, it will cause an increase in the unit pressure in the middle of the tire tread, exacerbate wear, and cause wear in the center of the tire crown, affecting comfort and reducing tire life; At the same time, it can also reduce tire grip (especially on slippery roads, which can affect braking distance), and accelerate tire wear speed, leading to uneven tire wear.

低胎壓：與高胎壓磨損相反，胎壓過低，則胎冠內縮，會導致輪胎兩側的磨損。而且，胎壓低與扁平比小有類似情況，胎側受擠壓時，輪轂與地面直接撞擊，也很容易造成簾布層線的斷裂，要么爆胎，要么鼓包。

Low tire pressure: Contrary to the wear center of high tire pressure, if the tire pressure is too low, the tire crown will retract and cause wear on both sides of the tire. Moreover, there is a similar situation between low tire pressure and low flat ratio. When the sidewall is compressed, the wheel hub directly impacts the ground, which can easily cause the cord to break, either causing a tire blowout or bulging.

胎壓的高低，在安全性、舒適性、經濟性也有一些影響，合適的胎壓，不僅可以保障行車安全，還可以帶來更舒適的駕駛體驗。更多相關事項就來我們網站http://m.cnjqf.com咨詢了解吧！
