How long do truck tires have to be renewed?

Tires are the only parts in contact with the road during vehicle driving, not only to bear the weight of the body, but also to deal with rain and snow, sand, potholes and other road conditions, bear a variety of deformation, load, stress and high and low temperature pressure, and driving safety is closely related.

Tires belong to a more typical consumable, the owner usually to do a good job of inspection and maintenance, especially cargo vehicles, the use of conditions are more complex, in order to ensure driving safety, once found tire problems to timely maintenance or replacement.

Under normal circumstances, the replacement cycle of truck tires is about 40,000-60,000 kilometers or 3-5 years, and after this period, the tires are prone to aging, cracking, surface hardening and other phenomena. Of course, as a kind of vehicle parts that are easy to wear, the replacement of tires must not rely on simple data to support, after all, different use conditions, driving road conditions, tire brands and quality will have an impact on the service life of tires, owners still have to decide whether to replace tires according to the actual situation.

The first is to see whether the tire surface cracks, bulging, rubber loss, pattern wear and other phenomena. Especially bulging, indicating that the metal coil inside the tire has been deformed or broken, if you continue to drive it is very easy to lead to a burst tire, very dangerous, must be replaced immediately. Secondly, when the tire surface pattern is seriously worn, it is also necessary to change the tire in time, because the grip of such a tire is greatly reduced, and it is easy to cause the vehicle to lose control in the wet road.

In addition, the owner can also determine whether the tire needs to be changed by the wear mark on the tire. Under normal circumstances, the tire tread groove at the bottom of the wear mark will be set, the passenger car is about 1.6 mm, the truck is about 2.4 mm, if the tire pattern is flush with this sign, it means that the tire should be changed.

When changing the tire, the car mainly tries to choose new tires, and the elasticity of tires will decline if the inventory is too long. The production date of the tire can be judged by the number near the tire tire hub, generally the first two numbers are the production cycle, the last two numbers are the production year, the owner can choose according to this information.

In addition, it is also very important to do regular tire transposition, the principle is: "inside for outside, outside for inside, cross replacement, all tires should be moved", so that the degree of loss of each tire can be as consistent as possible, extending its service life. The following Daro trailer axle according to several common freight models, a simple introduction to the method of changing the tire.

Note:

1, if the tire size pattern is not the same, the front and rear tires should not be transposed.

2, tire transposition should be combined with regular maintenance cycle, transposition method selected, should not be arbitrarily changed.

3. For tires with directional patterns, the rotation direction cannot be changed after transposition.

4. After the tire transposition, the tire pressure should be re-adjusted according to the regulations.

5, if the tire wear difference is large, can increase the frequency of transposition.
