When tires are replaced in pairs, the new tires should always be installed on the rear axle, and the partially worn tires should be moved to the front. Driving with new tires on the rear axle can help the vehicle to maintain control on wet roads because the tires with deeper treads are more likely to resist hydroplaning. When front tires have less tread than the tires on the rear axle, the vehicle is generally considered easier to control, since sliding would likely be the result of an understeer –which is easier for the driver to control by decreasing throttle. If worn tires are placed on the rear axle and a slide occurs, it’s likely the result of an oversteer (where the rear of the vehicle continues to move straight ahead). Oversteering is generally harder to recover from and decreasing throttle may actually amplify the negative effects of the oversteer.
awd四个一起换 fwd可以换两个 但是如果磨损差异太大的话 还是要全换

具体原因如下: 旧的轮胎跟新的比,相对摩擦力差。在地面很滑,还需要快速拐弯的极限情况下:
前轮旧,会under steering,俗称推头。就是打了方向盘,车还直的往前冲,不想拐弯。出了车祸,车头先撞上,有缓冲相对安全。 后轮旧,会over steering,俗称甩尾。就打了很小打了的方向盘,车却大幅度拐弯甚至旋转。出了车祸,侧面可能先撞上,相对更危险。
所以宁肯前后轮都是旧胎,这样就不会推头和甩尾了吧。
那可以漂移了😄 (Neural steering)
