隨著氣溫不斷下降，輪胎又將面臨重重考驗。除了輪胎正常磨損及以外破損外，影響輪胎壽命的另一大命門，便是大家常常容易忽略的胎壓。
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.
合適的胎壓有何好處
What are the benefits of appropriate tire pressure
當車輛行駛胎壓在合理區間內，不僅可以降低輪胎損壞的風險，還能延長使用壽命。此時，車輛油耗和駕乘舒適性也恰好處于一個較為平衡的狀態。
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.
胎壓過高，可能出現的問題
Possible issues with high tire pressure
①胎壓過高會使輪胎的剛性增強，當車輛壓過路面接縫或者坑洼時，震動便會更生硬的傳遞到懸架上，使車輛的行駛質感變得更加顛簸；
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胎壓過高時，從輪胎正面視角看，胎面中間部分會相對“凸”出，這也意味著輪胎的接地面積會降低，進而影響輪胎的抓地力；
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胎壓過高時，行駛過程中胎噪也會隨之增加。
③ When the tire pressure is too high, the tire noise will also increase during driving.
胎壓過低，可能出現的問題
Possible issues with low tire pressure
①過低的胎壓，會加大輪胎行駛時的形變量，胎壁長期過度形變，可能影響輪胎使用壽命，增加爆胎風險；
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胎壓過低時駕駛，輪胎與地面的接觸面積會增加，從而增加摩擦阻力，增加車輛油耗。
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.
胎壓調節
Tire pressure regulation
各個車型具體胎壓標準，可詳見車輛左中柱銘牌。條件允許的情況下，車友們可選擇充氮氣，不僅不易熱脹冷縮，還能降低到胎噪。
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.
