How to identify tire safety?

1. Tire contact area The entire vehicle relies on the four contact surfaces of the tire and the ground to provide adhesion, and each contact area is only one postcard size.

According to statistics from relevant departments on traffic accidents on the expressway, 46% of traffic accidents were caused by tire failures, among which the accidents caused by tire bursts accounted for more than 70%, and the problems caused by improper use of tires accounted for above 95.

2. Routine maintenance and maintenance of tires Observe the obvious tire problems habitually, see if the tire pressure is normal, whether there is any fine foreign matter penetrates the tread, whether the tread pattern has worn to the need to replace the tire, etc., and regularly go to the Goodyear authorized service center. Tire for routine maintenance.

At least once a quarter to a professional tire store tire balance, it will not only help to extend the life of the tire and the normal performance of vehicle performance, but also help the driver's life safety.

Every six months or ten thousand kilometers to do a positioning. Usually, if a vehicle hits a gravel road or travels on a rough road, the positioning will be damaged.

Frequent transposition helps to ensure that the tire wears evenly, thereby prolonging the service life of the tire. In general, front-wheel-drive vehicles should be transposed every 8000-10,000 km, while four-wheel-drive vehicles need to be transposed every 6,000 km.

3. Understanding Common Tire Problems Tire noise occurs after a certain period of use, basically due to incorrect tire pressure or improperly positioned wheels, resulting in uneven tread pattern wear. After the use of the tire bulging, often because the tire was subjected to external force collision and extrusion caused by broken cords, such tires can no longer be used, otherwise it will cause a traffic accident due to puncture. If the vehicle is found to be shaking, the steering device, suspension device and tires should be inspected. If the phenomenon of shaking is ignored, excessive wear of the tire and suspension will result, and even become a safety hazard.

In case of tyre deflation, the vehicle should be parked on the straight edge of the straight road. If on the slope, the stopper must be placed behind the front wheel or the rear wheel, turn on the warning light, place the warning sign behind the vehicle, and loosen the wheel with a wrench. Circle the screw, and then place the jack on the lifting point under the car. After the body is fully lifted, remove the screw and tire, replace the spare tire, tighten the screw, adjust the tire pressure, and tighten the valve.
