"Training the car before raising the tire" should pay attention to the problem of tire maintenance

"Training tires first" is a truth that many car owners know. What can be done in tire maintenance to maintain tires to the greatest extent and ensure a high safety factor? "Tire Knowing Hall" has been in three consecutive phases Consumers introduced the knowledge of tires. We aim to introduce various precautions in detail from the aspects of "installation", "use" and daily maintenance of tires, hoping to help consumers, so as to avoid the owner's tires Some misunderstandings of conservation.

In this issue of Tire Knowing Hall, on the basis of the "installation" and "use" of previous tires, we will mainly introduce the issues that should be paid attention to in the maintenance of tires in the daily life of car owners.

First, the tire pressure must be accurate. The standard tire pressure of a tire is about 2.2 to 2.6 bar. Too high a tire pressure tends to increase the wear of the tire and may also cause a flat tire, while too low will increase fuel consumption and vehicle bumpiness. Generally speaking, the tire pressure can be lower in summer and higher in winter.

The owner can prepare a tire pressure gauge. The best time to measure the tire pressure is to get up in the morning and measure the tire pressure before starting the vehicle, because the tire will completely cool down after driving for 4 hours. The data measured at this time The most accurate. The standard tire pressure of the tire is usually near the door. Compare the standard value and the measured value. If it is too high, let go of some gas, and vice versa.

Second, pay attention to four rounds of transposition. If the vehicle has problems such as running deviation, steering wheel sinking, and one-sided wear of the tires, these phenomena are reminding the owner to immediately adjust the four-wheel positioning of the vehicle. Due to the steering wheel, the front wheels wear faster than the rear wheels. In order to extend the service life of the tires, the tires are regularly replaced, so that the tires can be evenly worn. Auto repair experts recommend that front-wheel-drive vehicles do four-wheel transposition every 8,000 kilometers.

In addition, keep the tires clean. Owners need to regularly check whether there are stones and other foreign objects in the grooves of the tires. If they have to clean them by themselves, but if they are spiked objects such as iron nails, they need to seek help from a professional maintenance organization. Check the tire sidewalls for punctures and stab wounds to see if cords are exposed, and if so, replace the tires in time. At the same time, we must pay attention to the warranty period of the tire. The service life of the tire is generally 2-3 years or about 60,000 to 100,000 kilometers. When the depth of the pattern is 1.6mm (minimum wear), the tire should be replaced immediately. Tires that have exceeded their shelf life (especially spare tires, whose spare tire life is roughly 3 years) have declined in overall performance.

As the saying goes "tires are divided into three parts, five parts are used, two parts are installed", in fact, the service life of tires is affected by other factors such as weather conditions, road conditions, vehicle technical conditions, etc. in addition to wear and mileage Owners need to check their car's tires more. At the same time, remind the majority of car owners that the repaired tires should be more careful and need more inspection.
