随着气温不断下降，轮胎又将面临重重考验。除了轮胎正常磨损及以外破损外，影响轮胎寿命的另一大命门，便是大家常常容易忽略的胎压。
As the temperature continues to drop, the tires will face numerous challenges again. In addition to normal tire wear and external damage, another major lifeline that affects tire life is often overlooked tire pressure.
合适的胎压有何好处
What are the benefits of appropriate tire pressure
当车辆行驶胎压在合理区间内，不仅可以降低轮胎损坏的风险，还能延长使用寿命。此时，车辆油耗和驾乘舒适性也恰好处于一个较为平衡的状态。
When the tire pressure of the vehicle is within a reasonable range, it can not only reduce the risk of tire damage, but also extend its service life. At this point, the vehicle's fuel consumption and driving comfort are also in a relatively balanced state.
胎压过高，可能出现的问题
Possible issues with high tire pressure
①胎压过高会使轮胎的刚性增强，当车辆压过路面接缝或者坑洼时，震动便会更生硬的传递到悬架上，使车辆的行驶质感变得更加颠簸；
① Excessive tire pressure can increase the rigidity of the tires. When the vehicle passes through road seams or potholes, vibrations will be transmitted harder to the suspension, making the driving experience more bumpy;
②胎压过高时，从轮胎正面视角看，胎面中间部分会相对“凸”出，这也意味着轮胎的接地面积会降低，进而影响轮胎的抓地力；
② When the tire pressure is too high, from the front view of the tire, the middle part of the tread will relatively protrude, which also means that the tire's contact area will decrease, thereby affecting the tire's grip;
③胎压过高时，行驶过程中胎噪也会随之增加。
③ When the tire pressure is too high, the tire noise will also increase during driving.
胎压过低，可能出现的问题
Possible issues with low tire pressure
①过低的胎压，会加大轮胎行驶时的形变量，胎壁长期过度形变，可能影响轮胎使用寿命，增加爆胎风险；
① Low tire pressure can increase the deformation of the tire while driving, and long-term excessive deformation of the tire wall may affect the service life of the tire and increase the risk of tire blowout;
②胎压过低时驾驶，轮胎与地面的接触面积会增加，从而增加摩擦阻力，增加车辆油耗。
② When driving with low tire pressure, the contact area between the tire and the ground will increase, thereby increasing frictional resistance and fuel consumption of the vehicle.
胎压调节
Tire pressure regulation
各个车型具体胎压标准，可详见车辆左中柱铭牌。条件允许的情况下，车友们可选择充氮气，不仅不易热胀冷缩，还能降低到胎噪。
The specific tire pressure standards for each vehicle model can be found on the left center pillar nameplate of the vehicle. If conditions permit, car enthusiasts can choose to charge nitrogen, which not only reduces thermal expansion and contraction, but also reduces tire noise.
