Tires should be replaced every 3 years or 60,000 kilometers, with a maximum service life of 5 years or 60,000 to 80,000 kilometers. Moreover, when changing to new tires, car owners must pay attention to the production date; otherwise, they may end up with old tires that look new but are of a certain age, which can also pose safety risks. Tires are rubber products. Over time, rubber will also age and deteriorate. Tires with a production date over three years should be purchased with caution. It is even more important not to choose products with a production date over five years. It is best to select tires from the current year or the previous year, and the closer to the current date, the better. Moreover, tires, as the only component in contact with the ground, are closely related to driving safety. However, according to a survey, many tires that have been in use for over five years are still in use. Many car owners will wait until a tire bursts and cannot be repaired before replacing it.

The specific situation should be determined based on the local roads and the specific usage conditions. Under normal circumstances, there are wear marks in the grooves of tires. Once the marks are exposed or worn flat, they should be replaced as soon as possible. Overused tires can cause dangerous skidding, resulting in failure to stop or rollover while driving. During use, if the steel cord is exposed or the rubber breaks, it is very dangerous and cannot be used anymore. It needs to be replaced immediately.

In addition, if there is a bulge or depression, it should be replaced immediately. When purchasing tires, in addition to the production date, it is also necessary to check whether there are any differences in the rubber materials used for the tread and sidewall to prevent yourself from buying retreaded tires. At the same time, it is best to replace the tires with those of the original size. After the old tires are removed and the new ones are reinstalled, the weight is different. It is necessary to do a dynamic balance for the car. If not, the car may veer off course. When using tires for a long time, it is best to have a four-wheel alignment and dynamic balance done for the car, which makes it safer to use. Steering wheel logo
