In winter, tires, rubber can harden it becomes relatively fragile, will reduce the friction coefficient, so it requires the tire pressure is too high, but more is low, the outside temperature is low, tire pressure is too low, soft tyres can be accelerated aging, serious and aggravate tire contact with the ground, will accelerate friction, reduce the tire life. So the maintenance of tires, is also very important.
　　1. Choose better winter tires for replacement. Because of the cold weather, tire rubber also hardens in the summer, and even though many cars have all-season tires, icy, slippery surfaces can test the grip of tires. In order to drive safely, it is necessary to change winter tires.
　　2, pay attention to the tire pressure of the vehicle, in order to ensure that each side of the front and rear tire surface are fully in contact with the ground, to achieve the best effect of grasping the ground, at the same time, the appropriate tire pressure can reduce the vibration of the road surface, increase the driving comfort, and fuel economy for the owner.
　　3, pay attention to the maintenance of tire side, must be regularly checked to ensure good condition, driving safety.
