济南沃尔沃汽车专修人员建议大家把轮胎胎压值，比车辆建议轮胎胎压值适当高0.1~0.2。由于冬天气温波动相对于夏天而言没那么大。即使跑高，速轮胎上升的温度也比夏天上升的温度要慢，所以轮胎里面气体的膨胀系数会相对比夏天是要小。夏天轮胎充到2.3跑高速，可能达到2.8。冬天轮胎充到2.5跑高速，可能也就到2.7左右。

Jinan Volvo Car repair personnel suggest that the tire pressure value should be 0.1~0.2 higher than the recommended tire pressure value of the vehicle. Because the temperature fluctuation in winter is not as large as that in summer. Even when running high, the temperature of the speed tire will rise slower than that in summer, so the inflation coefficient of the gas in the tire will be relatively smaller than that in summer. In summer, when the tyres are inflated to 2.3, the speed may reach 2.8. In winter, when the tires are inflated to 2.5, the speed may reach about 2.7.

胎压异常的危害：

Hazards of abnormal tire pressure:

胎压过低：胎压过低时，明显的现象即车子的油耗会上升。因为若汽车的胎压过低，会增加车子轮胎与地面的摩擦，运行阻力因此增加，引起出现汽车油耗增加的状况。同时因为摩擦力的增大会令轮胎的温度升高，导致轮胎变软，因此使用强度也会下降。如果长时间保持高速行驶，甚至会导致爆胎的现象，同时还会伴随着方向盘变沉、跑偏现象的出现。

Low tire pressure: When the tire pressure is too low, the obvious phenomenon is that the fuel consumption of the car will rise. Because if the tire pressure of the car is too low, the friction between the car's tires and the ground will increase, and the running resistance will increase, resulting in an increase in fuel consumption. At the same time, because the increase of friction will increase the temperature of the tire, resulting in the tire becoming soft, so the use strength will also decrease. If you keep driving at high speed for a long time, it may even lead to a flat tire, and at the same time, it will also be accompanied by the phenomenon of steering wheel sinking and deviation.

胎压过高：如果轮胎的胎压过高，会降低轮胎与地面的摩擦，与此同时也会降低汽车轮胎的附着力，尤其是在紧急情况下的制动能力不好，会威胁到行车安全。不仅如此，在开车过程中还会感到方向盘的震动，同时有方向跑偏等现象，因此会影响到在开车时的舒适性。

Too high tire pressure: if the tire pressure is too high, it will reduce the friction between the tire and the ground, and at the same time, it will also reduce the adhesion of the car tire, especially the poor braking ability in emergency situations, which will threaten the driving safety. Not only that, but also the vibration of the steering wheel will be felt during driving, and there will be steering deviation and other phenomena, which will affect the comfort of driving.

如果轮胎胎压过高，还会加快轮胎部花纹的磨损，同时还会影响车子的排水性以及使用寿命。当轮胎轧过钉子或者是碎玻璃的时候很容易被扎爆胎，这些都是胎压过高引起的安全隐患。

If the tire pressure is too high, it will also accelerate the wear of the tread pattern at the center of the tire, and also affect the drainage and service life of the car. It is easy to be punctured and burst when the tire runs over nails or broken glass, which are potential safety hazards caused by high tire pressure.

如果是在汽车刚停下后要给轮胎充气，要先让汽车停在原地散热后再充气。因为轮胎的温度会对胎压造成影响，可能当时胎压达到了标准，但是等轮胎降温后，胎压就降下去了。充气时切记不要想着充过了无所谓，把气放出来就可以了。轮胎充气过多，会导致连线过分深交使轮胎的强度降低。更多相关内容就来我们网站http://www.lutongqixiu.com咨询吧！

If you want to inflate the tire after the car has just stopped, you should first let the car stop in place to dissipate heat and then inflate it. Because the tire temperature will affect the tire pressure, the tire pressure may have reached the standard at that time, but the tire pressure will drop after the tire cools down. When inflating, remember not to think that it doesn't matter if you have filled it, just let it out. Too much tire inflation will lead to too deep connection and lower tire strength.
