When do car tires change? How long does it take to change a car tire

The life of tires varies according to the quality of the tires, the technical condition of the car, the road conditions, etc. Generally, there is a thin slit on the pattern of the tire, which is the wear and tear indicator line of the tire, once this line is smoothed, that is, it disappears, even if the other parts are still good, the tire must be replaced. According to experience, the car is generally 5 60,000 kilometers to pay attention to the observation and prepare to change the tire.

The normal life of a tire is two years or 60,000 kilometers, whichever comes first. Remember the age of the tyre and do not use a tyre that is more than 6 years old, whether it has been used or not. Tires will deteriorate with their age, and as with their use, tires should always be inspected and balanced by a recognized manufacturer, and the condition of the tire should be explained as much as possible after an accident, no matter how minor the accident.

In addition, every 10,000 kilometers driven, the tires must be reversed, and after the adjustment, the tire pressure must be adjusted at the same time. After the aluminum alloy steel rim is replaced, the steel rim nut should be tightened again after the first driving of 1000 kilometers, and the same is true after the tire breakage.

The tire is one of the important parts of the car, which is in direct contact with the road surface, and the car suspension works together to alleviate the impact of the car when driving, and ensure that the car has good ride comfort and driving smoothness; Ensure that the wheels and the road surface have good adhesion, and improve the traction, braking and passability of the car; Bearing the weight of the car, the important role played by tires in the car is becoming more and more important.

Hello! Car tires need to be replaced in the following five situations:

1. When the tire is worn to the wear limit mark, it must be stopped (that is, the tread depth is less than mm).

2. Tire aging.

3. Tires with deformed tread or bead damage, tires damaged by sidewall crushed due to airless driving, and tires corroded by chemicals shall not continue to be used.

4. Bulging tires shall not continue to be used.

5. If other damage affects the safety of the tire, it shall not be used continuously.

Depending on how worn your tires are, and if you hear the tires loud enough to drown out the sound of the engine, the tires are about to be replaced.

Look at the degree of wear and tear of the appearance, and the specific use of the situation.

Car owners often do not pay attention to the condition of the tires when driving, but the condition of the tires is often related to driving safety, therefore, car owners need to pay attention to the condition of the tires in order to replace them in time. So how often do you need to change your tires? In fact, there are certain skills that can be followed, so let's listen to the introduction.

The pattern is almost worn out and can be replaced.

When replacing tires, Wang is generally in 2-3 years or about 6-100,000 kilometers of travel

1. China's laws and regulations stipulate that the pattern on the surface of the tire must be replaced when it is worn out, but in actual driving, if it really reaches this level, the performance of the tire will become very poor;

2. The grip and drainage capacity will deteriorate, and the safety will also be reduced, so foreign tire experts have said that the tread must be retained at least 3 mm to be considered safe;

3. If calculated according to the mileage, the United States had a test report last year showing that the mileage of the more common four-season tires is generally more than 10,000 kilometers, if the slightly worse tires can also run about 100,000 kilometers, if in order to ensure safety, then in fact, running 80,000 kilometers is no problem.

The quality of a car tire is related to whether our car is safe, speaking of which, many people may be curious about how often the tires are replaced for family cars? Next, I will give you an analysis and analysis.

The general service life of tires is about 3 years and 8w kilometers, which is not absolute, because the use of tires has a great relationship with the road surface, the service life is long if the road surface is smooth, and the service life of the tire will definitely be reduced if the road surface is bumpy or gravel road. Let's talk about the most common judgment points that need to be replaced in tires.

1. Judgment of the depth of the tire pattern: the tire pattern directly affects the grip of the tire and the stability of the vehicle, if the tire pattern is too thin or even does not cause the vehicle to brake longer distance, it is easy to slip in rainy days. Therefore, it is necessary to check the tire tread depth regularly.

Generally, each tire will have a tire pattern wear mark, if the tire is worn to this mark, the tire needs to be replaced, that is, the tire pattern depth is less. As a reminder, it is best to replace the tires on the same axial basis together, because the new and old tires have different tread depths and different grips, which may cause the vehicle to mistrack and slip sideways.

2.Tire rubber aging judgment: In fact, the number of kilometers traveled by family cars every day is not very much, so there are not many wear to the pattern limit mark, but the phenomenon of tire aging is many, and the most common tire rubber aging is that the surface of the tire is cracked and there are many small cracks, which is called tire cracking.

Because tire rubber requires a certain hardness, there is a process called vulcanization during manufacturing. Vulcanized rubber increases its hardness, but it deteriorates over time. Therefore, the general service life of tires is about 3 years.

Depending on the shelf life of the tire: the sidewall of the tyre will have a four-digit number indicating the date the tyre was manufactured, with the first two representing the number of weeks and the last two representing the year.

The use of tires should generally not exceed 3 years, and the mileage should not exceed 60,000 kilometers. While a little over the years and mileage doesn't hurt the big picture, the cold temperatures in the winter and the rain in the summer can stretch the wet grip and dry handling of the tires.

Pay more attention to the sidewall: As the tire rubber gradually ages, the sidewall of the tire will appear to be deeply wrinkled. However, as long as the sidewall of the tire has not been hit and the cord has not been broken, it can continue to be used.

The triangular logo on the sidewall of the tire can help the owner find a protrusion in the groove of the crown of the tire, which can determine the actual wear limit of the tire, which should be greater than millimeters.

Choose the right tires correctly.

Car tires: can be divided into ordinary car tires, station wagon tires and sports tires. Ordinary car tires will focus on comfort, reduced energy consumption and improved durability; Station wagon tires tend to increase the weight and durability of the tire; Sports tires are more focused on handling.

Off-road tires: can be divided into high-speed tires, mud tires and comprehensive tires. High-speed tires are suitable for paved road driving, but the sidewall support is slightly weaker; Dirt tires have a deeper tread pattern and are suitable for driving on unpaved roads, but the fuel consumption of the vehicle will be slightly higher; Comprehensive tires have the advantages of both, and eliminate the disadvantages of both, but both have made concessions.

Tire change according to usage.

If you're choosing tires for the average family car, consider Michelin's EnergyXM1, Bridgestone Turanzatr80 or Goodyear Eaglenct 5, three tyres that focus on road comfort. If you are changing tires for off-road vehicles, we recommend the A T tires of Breluchi, which take into account the comfort of road driving and the handling of non-paved roads.

New tires are replaced every four years.

Under normal circumstances, tires can be used for four years when installed on a car, so it is recommended that you replace the tires every four years. If the tires have not been used for four years but the tread depth has worn out to the warning line, then they should also be replaced. The tire is an important part of the car, this part is the only part of the car that is in contact with the ground, and this part will be directly related to the driving stability and driving safety of the car.
