Q:我的车不是原尺寸的备胎,如果需要用到的时候会不会影响安全?A:小尺寸备胎装在后轮时,和未更换备胎前制动性能并没有太大差距。但是把小备胎装在前轮就会影响制动效果。因为把小备胎装到前轴的情况下,再强的制动系统都施展不开了。这主要是因为前轴的小备胎在紧急制动时会更容易抱死,这个时候ABS和EBD为了不让车辆失控就会控制另一侧前轮的制动力迁就这个小备胎。这样原本抓地性充足的另一个前轮只能发挥出和小备胎差不多的制动力来保持制动平衡。另外
Q: My car is not the original size of the spare tire, if you need to use it will not affect the safety? A: Small size spare tire installed in the rear wheel, and did not replace the spare tire before the brake performance and not much difference . However, the small spare tire mounted on the front wheel will affect the braking effect. Because the small spare tire mounted to the front axle of the case, then the strong braking system is not open to display. This is mainly because the small spare wheel on the front axle will be more easily locked during emergency braking. At this time, ABS and EBD will control the braking force of the other front wheel to accommodate the small spare wheel so as to prevent the vehicle from losing control. In this way, the other front wheel, which has enough grip, can only exert braking force equal to that of a small spare tire to maintain the balance. In addition
