The Kumho Tire Incident has caused more and more owners to focus on car tires. What should consumers pay attention to when buying tires? How to maintain it to extend its service life?

Most owners don’t know “tires”

“I don’t know how to protect the tires.” Today, in an auto maintenance store on Longmen Avenue, the owner Lin Xiaoning said that he has been buying cars for more than two years and rarely checks tires. A number of car 4S shop owners also said that many owners do not know the car tire brand, do not know how to maintain the tires.

According to Zhang Yufeng, after sales and maintenance manager of Guangli Xunli Store, the numbers on the tires not only represent its brand, but also indicate the important information on traffic safety in terms of load index, speed grade, and manufacturing time. The owner must have a good idea.

When picking up tires and using car tires for a long time, it will definitely need to be replaced. Then what should the driver pay attention to when replacing the tires?

It is understood that the use of ordinary tires, storage life is about three years, the tire production lot number is used to identify the new and old tires and storage time, such as the ordinary tire's factory time if marked is "1011", it shows that 2011 is the 10 weeks out of factory.

Zhang Yufeng introduced that the general household cars should adopt rules with small pattern tires, and when changing tires, special attention should be paid to whether they are retreaded tires. The owner can use two methods to judge: At first glance, the new tire tread presents blue light and the color is more natural. The retreaded tires are particularly bright; on the other hand, rubber tires and wear marks on new tire treads are not easily torn down, and fingerprints are not left when they are touched.

Three kinds of habits can extend tire life. Zhang Yufeng introduced that three habits can extend the service life of tires.

One is to do the habit of checking tire pressure at any time. Air pressure is the key to prolong tire life. Tyre pressure often exceeds 20% of normal air pressure, and tire life is reduced by 10%. If it is often below 30% of normal air pressure, tire life will be reduced by 52%.

The second is to develop a habit of slowing down. Some drivers do not slow down when passing the deceleration belt. If this is done for a long time, it will not only accelerate the wear of the tread rubber, but also make it extremely easy to puncture the tire.

The third is to develop the habit of regularly removing foreign objects inside tires. When the vehicle is driving on the road, there are often stones that squeeze into the cracks in the tire. If these pebbles are not cleared in time, they will puncture the tires over time, resulting in leaks or punctures.
