The maximum service life of the tire is several years, how to judge whether to replace it

With the exception of broken, bulging tires, tire life (replacement) is determined by two indicators:1Time. 2.Degree of wear. Which item comes first and which item is replaced by which.

Because of the weight of the car itself, daily light load, full load, tire quality, etc., these factors will have different or even greater tire wear under the same mileage. And many car owners can't remember the mileage at all after changing tires. The following two methods can be self-tested:

1.Look at the tire: between the tire treads, there are several annular grooves around the tire, and there will be a "bump" mark (mm height) at intervals between the grooves, which is lower than the tire tread next to it, and when the tire pattern is worn to the same level as this bump, it means that it needs to be replaced.

This is a mark that many manufacturers have designed to use as a safe tire (but not all brands of tires have this mark).

2.Use a special measuring tape to measure the degree of wear of the tread: the measuring tape is red, yellow and green.

When using, the expansion part of the measuring tape is against the bottom of the tire pattern to check the color: green is good; Yellow Critical; Red replaced. There is no color of the scale to see the scale:

Equal to or less than millimeters to be replaced.

1. The normal service life of car tires is about 3 years, and they should be replaced when the car travels to 50,000 kilometers. Long-term use of tires that have been in service for more than a few years will not only affect the stability of the car when driving, bring potential safety hazards to the car, but also reduce the grip of the car and increase the fuel consumption of the car. In addition to replacing the tires that have reached the service life in time, the owner should also regularly do some front and rear wheel crossing, test tire pressure, dynamic balance and other testing items, which can not only ensure the safety of the car, but also provide stronger power for the car.

2. Simply judge the experience of automobile tires, pay attention to the cracks of the tires, if the cracks on the side are deep, they should be replaced, safety first.

Tires are changed once every 3 years, if the vehicle is driven 20,000 kilometers a year, it can be replaced in 2 to 3 years, and if it is driven about 10,000 kilometers a year, it should also be replaced in 4 to 5 years.

The tire service life is up to 5 years. Tires need to be replaced 5 years after they leave the factory, regardless of how worn they are. Many car owners think that the tires should be replaced after driving 45,000 kilometers.

In fact, the replacement of tires has a certain relationship with the kilometers traveled by the vehicle, but it is not very related. Generally, after the tires run 50,000 kilometers, it is not a safe period, theoretically speaking, the tires should be replaced, but now private cars are rarely replaced so early, one is that the owner cherishes the car, and the other is that the road conditions of the vehicle are better. As long as the owner does not often speed up, drag racing, tail flicking, sudden braking, etc., and the tire uses 78,000 kilometers, it is not a big problem.

Regularly review the vehicle's tire wear mark baseline, and when the tire wear on the outside of the tire reaches the baseline for that replacement, the tire needs to be replaced. When there is uneven wear on the tread or edge, or when there is bulging on the side of the tire, the tire should be replaced in time.

The age of the tire.

If you don't care about the number of kilometers, just look at the number of years, generally six to eight years, about seven years. There is never an accurate, consistent, and standard answer to this question, because there are many objective factors involved.

For example, the usual driving conditions, personal driving habits, the usual frequency of use, whether it has been hit, etc., will seriously affect the service life of tires.

For example, if you have just changed a tire, you have finished your durability on the road and the sidewall is cracked, in this case, you must replace the tire in time.

Moreover, the service life of tires should not only look at the age, but also flexibly judge the mileage driven. The life of tires that run 10,000 kilometers a year and tires that run 30,000 kilometers a year is definitely not the same.

The number of kilometers driven, the pattern on the surface of the tire is naturally worn out, if the pattern on the surface of the tire is worn out, it must be replaced in time.

However, it should be noted that even if one kilometer of Duchangqin is not driven, the tires must be replaced after 8 years, because of the aging factors involved.

Aging tires greatly increase the risk of punctures, and the likelihood of danger also greatly increases. (Photo by Q&A: Q&A called the beast) @2019
