濟(jì)南沃爾沃汽車專修人員建議大家把輪胎胎壓值，比車輛建議輪胎胎壓值適當(dāng)高0.1~0.2。由于冬天氣溫波動(dòng)相對(duì)于夏天而言沒那么大。即使跑高，速輪胎上升的溫度也比夏天上升的溫度要慢，所以輪胎里面氣體的膨脹系數(shù)會(huì)相對(duì)比夏天是要小。夏天輪胎充到2.3跑高速，可能達(dá)到2.8。冬天輪胎充到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.

胎壓異常的危害：

Hazards of abnormal tire pressure:

胎壓過低：胎壓過低時(shí)，明顯的現(xiàn)象即車子的油耗會(huì)上升。因?yàn)槿羝嚨奶哼^低，會(huì)增加車子輪胎與地面的摩擦，運(yùn)行阻力因此增加，引起出現(xiàn)汽車油耗增加的狀況。同時(shí)因?yàn)槟Σ亮Φ脑龃髸?huì)令輪胎的溫度升高，導(dǎo)致輪胎變軟，因此使用強(qiáng)度也會(huì)下降。如果長時(shí)間保持高速行駛，甚至?xí)?dǎo)致爆胎的現(xiàn)象，同時(shí)還會(huì)伴隨著方向盤變沉、跑偏現(xiàn)象的出現(xiàn)。

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.

胎壓過高：如果輪胎的胎壓過高，會(huì)降低輪胎與地面的摩擦，與此同時(shí)也會(huì)降低汽車輪胎的附著力，尤其是在緊急情況下的制動(dòng)能力不好，會(huì)威脅到行車安全。不僅如此，在開車過程中還會(huì)感到方向盤的震動(dòng)，同時(shí)有方向跑偏等現(xiàn)象，因此會(huì)影響到在開車時(shí)的舒適性。

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.

如果輪胎胎壓過高，還會(huì)加快輪胎部花紋的磨損，同時(shí)還會(huì)影響車子的排水性以及使用壽命。當(dāng)輪胎軋過釘子或者是碎玻璃的時(shí)候很容易被扎爆胎，這些都是胎壓過高引起的安全隱患。

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.

如果是在汽車剛停下后要給輪胎充氣，要先讓汽車停在原地散熱后再充氣。因?yàn)檩喬サ臏囟葧?huì)對(duì)胎壓造成影響，可能當(dāng)時(shí)胎壓達(dá)到了標(biāo)準(zhǔn)，但是等輪胎降溫后，胎壓就降下去了。充氣時(shí)切記不要想著充過了無所謂，把氣放出來就可以了。輪胎充氣過多，會(huì)導(dǎo)致連線過分深交使輪胎的強(qiáng)度降低。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.nikond90.cn咨詢吧！

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.
