備胎不應長時間使用，它不是用來代替正胎長時間使用的，使用頻率較少，因此與地面的摩擦機會相對較少，如換上備胎后，因四條胎的摩擦系數(shù)不同，地面附著力不同，氣壓不同，長時間使用會對車輛的制動系統(tǒng)、轉(zhuǎn)向系統(tǒng)及懸掛系統(tǒng)產(chǎn)生一定的影響，給行車安全帶來極大的隱患。同時還會使同向的其他輪胎產(chǎn)生摩擦不均勻等現(xiàn)象 Spare tire should not be used for a long time, it is not is used instead of tyres used for long, use frequency is less, so the chance of friction with the ground is relatively small, such as after the spare tire, because of the four tires of different friction coefficient, the surface adhesion is different, different pressure, long time use of vehicle braking system, steering system and suspension system have influence, driving safety to bring huge hidden trouble. At the same time also can make other tire friction synthetic phenomenon such as uneven. 胎紋磨損到磨損標志線之前，要盡早對輪胎進行換，而輪胎的胎側(cè)有細小裂紋時，這種情況就不能跑長途或高速行車。因為輪胎側(cè)壁很薄，高速行車很容易發(fā)生爆胎。此外，由于前輪爆胎后電動汽車的方向不容易控制，如果是前胎胎側(cè)有裂紋，那么就要把它移到后輪或進行換。 Before tire wear to wear marker, to replace the tyres as soon as possible, and the sidewall of the tire has a small crack, this kind of situation will not be able to run long distance or driving at a high speed. Because of tire is very thin, flat tire high speed driving is easy to occur. In addition, because the front wheel puncture after the direction of the electric car is more is not easy to control, if there is a crack is a former tire sidewall, then move it to the rear wheels or be replaced. 為延長輪胎壽命和增加安全性，建議定期將輪胎掉換位置。輪胎換位的里程間隔并不是死數(shù)，原則上越勤越好，在實際使用中，可以根據(jù)輪胎的耐磨系數(shù)大致確定換里程。同樣前驅(qū)動前轉(zhuǎn)向的FF車型，不同輪胎的換位方式也不同。非對稱花紋輪胎胎面花紋不對稱，一邊寬一邊窄。安裝時分內(nèi)外，但換位時并不改變內(nèi)外方向，只改變輪胎轉(zhuǎn)動方向，因此可以和普通對稱花紋一樣直接將輪胎和鋼圈一起換位。 To extend tire life and increase security, the proposal will tire transfer position on a regular basis. Tyre transposition number range interval is not death, as often as possible in principle, in actual use, can according to the tire mileage wear-resisting coefficient defined roughly replaced. Drive before the same to the FF models, different ways of the transposition of the tire is also different. Asymmetric pattern tyre tread asymmetry, wide and narrow. Installed at the inside and outside, but they do not change the direction of inside and outside the transposition and only change the tire rotation, so you can like ordinary symmetric pattern rearrangement directly to the tires and rims.
