备胎不应长时间使用，它不是用来代替正胎长时间使用的，使用频率较少，因此与地面的摩擦机会相对较少，如换上备胎后，因四条胎的摩擦系数不同，地面附着力不同，气压不同，长时间使用会对车辆的制动系统、转向系统及悬挂系统产生一定的影响，给行车带来极大的隐患。同时还会使同向的其他轮胎产生摩擦不均匀等现象 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. 胎纹磨损到磨损标志线之前，要尽早对轮胎进行换，而轮胎的胎侧有细小裂纹时，这种情况就不能跑长途或高速行车。因为轮胎侧壁很薄，高速行车很容易发生爆胎。此外，由于前轮爆胎后电动汽车的方向不容易控制，如果是前胎胎侧有裂纹，那么就要把它移到后轮或进行换。 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. 为延长轮胎寿命和增加性，建议定期将轮胎掉换位置。轮胎换位的里程间隔并不是死数，原则上越勤越好，在实际使用中，可以根据轮胎的耐磨系数大致确定换里程。同样前驱动前转向的FF车型，不同轮胎的换位方式也不同。非对称花纹轮胎胎面花纹不对称，一边宽一边窄。安装时分内外，但换位时并不改变内外方向，只改变轮胎转动方向，因此可以和普通对称花纹一样直接将轮胎和钢圈一起换位。 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.
