低胎压爆胎几率为何是高胎压的2倍？
Why is the probability of a low tire pressure blowout twice that of a high tire pressure?
胎压过低，与地面接触的面积会变大，一方面会使轮胎和地面的摩擦系数加大，另一方面会造成轮胎滚动到下方时，胎侧橡胶帘布中的帘线受压变形过大，当轮胎滚动到上方，帘线在弹性和张力的作用下又要恢复原位，这会使内部的帘布层变形、加速疲劳，严重时造成结构性损伤。
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.
这种反复的变形，
济南哪里修奥迪比较人员说的直白一点说就是车主们小时候都玩过用手掰铁丝，铁丝在反复掰动后会发热，强度也会变软，更容易折断，轮胎内帘布层的胎体帘线也是这个道理。行驶时轮胎温度更高，会加速轮胎内帘布层的胎体帘线变形，轮胎结构出现不可逆的损伤，绷不住就爆了。
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.
胎压高时，整体刚性增强，虽然不会出现摩擦过热和过度屈曲，但遇到严重颠簸、高温、尖锐物体碰撞时也会出现鼓包或者爆胎的情况。如果只考虑正常驾驶因素，高速行驶的情况下胎压低无疑更容易引起爆胎！
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!
胎压不合适影响轮胎的寿命?
Does improper tire pressure affect the lifespan of tires?
通常轮胎标准充气压力2.2—2.8bar之间（冷胎压）正确轮胎充气压力。空载情况下，普通轿车一般是2.3bar左右，越野胎是2.5bar。胎压过高或者过低都会引起轮胎寿命缩短。
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.
高胎压：如果轮胎气压过高，轮胎的刚性增大，变形和接地面积减小，会导致使胎面中部的单位压力增大，磨损加剧，产生胎冠磨损现象，影响到舒适性并将降低轮胎寿；同时，还会使轮胎抓地力减少(尤其在湿滑路面，会影响制动距离)，也会造成轮胎的磨损速加快，导致轮胎磨损不均匀。
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.
低胎压：与高胎压磨损相反，胎压过低，则胎冠内缩，会导致轮胎两侧的磨损。而且，胎压低与扁平比小有类似情况，胎侧受挤压时，轮毂与地面直接撞击，也很容易造成帘布层线的断裂，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.
The level of tire pressure also has some impact on safety, comfort, and economy. An appropriate tire pressure can not only ensure driving safety, but also bring a more comfortable driving experience. For more related matters, come to our website http://www.lutongqixiu.com Consult and understand!
