The tires that were just replaced this year were found to be 15 years past the expiration date

1. Tires also have a shelf life, precautions for choosing tires. 2. Check the production date to choose tires and pick many daily necessities, you need to look at the production date. Because rubber-based tires have a lifespan, too long storage time of tires will affect their performance, and at worst, tire puncture accidents may occur and endanger lives.

3. Check the anti-counterfeiting logo In order not to be deceived by the merchant, we should check the anti-counterfeiting logo in addition to the production date when selecting tires. ** New tires will have anti-counterfeiting logos, which are generally pasted on the logo of the tire. 4. Observe the pattern shape of the tread tire is also very particular, the tires of the general family car are mixed tread tires, this kind of tire can meet the needs of most weather, and the owner does not need to replace the tire because of the weather.

If it is a tire that is usually used in a family car, it is recommended that you choose a mixed pattern tire, which has the advantage of being able to adapt to most weather and is perfect for use in a family car. 5. The load index and speed level of tiresIn ordinary life, I find that many friends often ignore the parameters of two tires when choosing tires, that is, the load index and speed level of tires. The load index of the tire represents the mass that the tire can carry, which is expressed by numbers; The speed class represents the maximum speed that the tyre can withstand, and is represented by letters, which are usually printed on the side of the tire.

The load index is a numerical representation of the maximum load that a tire can bear, to characterize the ability of the tire to bear the load, the larger the value, the greater the load that the tire can bear.

The use time of tires is affected by many external factors, such as climate, road conditions, driving habits, maintenance conditions, etc., under the conditions of good car condition, good driving habits, and good road conditions (the road surface is not very rough, there are not many curves), the general tires can be used for 3 to 5 years.

The date of manufacture of car tires is very easy to identify. In a small square on the sidewall of the tire, the date of manufacture of the tire is marked, consisting of four digits, the last two indicating the year and the first two indicating the number of weeks. In the figure below, "3513" indicates that the tire was produced in the 35th week of 2013, which is about September 2013.

The shelf life is 5 years or 6-80,000 kilometers, and new tires must be replaced.

The service life of tire products is 5 years or 6-80,000 kilometers, depending on the local road and specific use. As a kind of rubber products, tires will age with the use of time in the process of use, consumers should try to avoid the erosion of acid and alkaline substances in the use process, strictly prohibit overload, overspeed use, and often check the tire inflation pressure, to avoid small angle extrusion, cross-domain roadbed, curb, etc.

The best time to use tires is generally about 5 years, beyond which they will begin to age, which will deform the tire tread and there is a risk of puncture.

When buying tires, you should buy tires with a more recent production date to make sure you are getting tires that are still in top condition. Even so, it is inevitable that unscrupulous merchants will modify the production date on the tire without authorization, so consumers must pay more attention to observe whether the production date of the tire has been tampered with when purchasing.

Generally, manufacturers set the service life of tires at 3 years. If the vehicle is driven 20,000 kilometers a year, it can be considered for replacement in 2 to 3 years. If you drive about 10,000 kilometers a year, you should also consider replacing it in 4 or 5 years.

If you only drive 5,000 kilometers a year, it will take 4 to 5 years to consider replacement. Even if it is a brand new tire, it should be considered to replace it after 3 years. Therefore, the spare tire in the trunk of the car also needs to be maintained regularly, and the spare tire that has not been used for too long also needs to be updated.

There are several situations in which it is advisable to replace car tires in time:

1. If you use a small amount of vehicles for a long time, even if the vehicle has run thousands of kilometers in more than ten years, you have to change the tires, because the rubber has aged.

2. If the tire is repaired more than three times, it is recommended to replace the tire, and the inside of the repaired tire is padded, which is not good for heat dissipation at high speed and increases the danger.

3. Look at the wear mark, any brand of tire will set a wear mark at the bottom of the groove of the tread. The height of the wear mark for general car tires is millimeters, and the wear mark for heavy-duty tires is millimeters.

4. Cracks or bulges and other damages, or the expiration of the life limit; In the process of daily driving, tires may be punctured by foreign objects, or they may accidentally hit the curb of the road. Tire damage includes tread cracks, bulging tread, severe sidewall wear, and multiple punctures by foreign objects. In particular, pay attention to the phenomenon of bulging, and the tire may be in danger of bursting at any time.

Car tires are not covered by the warranty. Car tires are wear parts, and there is no way to guarantee them. It's not that this tire, after this is driven, it means that the road conditions are different, the degree of damage to this tire, including this wear is different, and there is no way to warrant this.

Even if you buy a new car and open the door of the 4S store, and there is a problem with this tire, this will not be warranted, and this tire is not covered by the warranty.

See. Questions.

Okay, got it. Okay

The tire life is generally about 3 years and 6w kilometers, because the spare tire is not used much, the kilometers will generally not arrive, but the year will come, so you need to see whether the rubber of the spare tire cracks, if it appears, you need to replace the tire.

Generally, the inventory of tires shall not exceed 3 years from the date of production, and the longest period of use shall not exceed 8 years.

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.

The position of tires in various parts of the automobile is very important, which has a great impact on the driving performance of the car, and the service life of the tire directly affects the economic benefits of transportation.

Because tires are consumables like engine oil and filters, there are no regulations in the state on the time and kilometers of use.

The following five situations need to be replaced: 1. The tire must be stopped when it is worn to the wear limit mark (that is, the tread depth is less than millimeters). 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.

During daily use.

1.Check the air pressure of all tires when cooled, including spare tires, at least once a month. 2.

Do not exceed the reasonable speed required by driving conditions and legal restrictions (e.g., slow down or avoid obstacles such as rocks and potholes in front of you). 3.

Regular wheel alignment and balancing is important to keep your driving safe and get the ideal mileage. 4.In order to achieve uniform wear and thus extend the service life of the tire, tire alignment is a must.

5.Protects tires from sunlight, oil, acids, and hydrocarbons. 6.

Good driving habits need to be practiced, such as: avoid emergency braking, slamming the steering wheel, etc.

A gentle driving style, proper tire maintenance can also extend the life of your tires.

It's usually about five years. All above are production dates.

Generally, the shelf life of tires is around 5 years.

By looking at the number on the tire sidewall, you can determine the production date of the tire and then determine if the tire needs to be replaced. For example, if the number on the tire shows 0717, it proves that the tire was produced in the 7th week of 17, and you can get a rough idea of the condition of your tire based on this.

Precautions: Tires are wearing parts, and their use scenarios and environments are different, which greatly affects their service life. When using, you need to pay attention to the degree of wear and tear of the tire.

Because during the shelf life, tires will be worn out due to braking, acceleration or poor road conditions, and some brand new tires may be used for more than a year, and they are already very worn, and they need to be replaced in time.

That is to say, in the process of use, pay attention to whether the tire has reached the wear boundary line, that is, the small bulges in the grooves on the tire tread. If it has worn to the warning point, it needs to be replaced immediately, without reference to the shelf life of the tire.

In addition, in addition to normal wear and tear, if the tire is impacted by an external force, causing its sidewall to bulge, or if it cannot continue driving due to puncture, etc., it is also necessary to replace the tire, whether it is new or not.

After the owner buys the tire, he does not know the shelf life of the tire, and is worried that the shelf life of the tire has passed, which will affect the quality of the tire and bring unnecessary safety hazards, so how many years is the shelf life of the tire?

Generally, the shelf life of tires is between 3-5 years, but because of the actual use of the vehicle, the service life of tires is also different. If the owner often drives on the road, such a road surface is relatively ordinary, so the shelf life of the tire is relatively long. If the owner often drives on bumpy or muddy roads, the shelf life may be shortened, generally about 3 years.

Of course, the above shelf life is the situation that the tires of the vehicle are not damaged, if once the tires of the vehicle are punctured or seriously worn, the owner can not refer to the shelf life of the tires, and the tires need to be replaced in time. If the outside of the tire is damaged, it cannot be repaired, and the owner can only choose to replace the tire, otherwise the vehicle will continue to drive There will be potential safety hazards.

The shelf life of tires is between 3-5 years.

Because the main raw material of automobile tires is rubber, its characteristic is that it will age over time, so that the performance of tires declines, and the general tire aging time is between 3 and 5 years, so when buying tires, you can choose tires with a high production date, and the production date is best within 1 year. Tire maintenance methods are: 1. Check the tire pressure regularly, tire pressure is an important factor affecting the life of the tire, not too high or too low, and inflate the tire pressure according to the vehicle marking; 2. Pick up the debris in the tread pattern frequently; 3. Reasonable control of vehicle speed, usually the tire speed level used in cars is mostly T, H and V; 4. Regularly check the wear and tear of tires.

The shelf life of tires is generally 3 years.

The state stipulates that the warranty period for tires is 3 years. Therefore, after three years, it is necessary to replace the tires with new ones, and their production and manufacturing dates cannot exceed three years. However, the vast majority of tires generally do not indicate the shelf life time, but the width of the standard pants indicates the date of manufacture.

It is recommended that when the owner removes the tires for the vehicle, it is recommended that it is better to choose the same brand of tires.

If the 4 tires are not of different types of brands, but belong to the same brand and its same model specifications, it can ensure that the owner of the vehicle will not have problems in the process of driving. On the other hand, if the owner chooses different brands of 4 tires, there may be problems during driving. And if the 4 tires are not repaired at the same time, there is a possibility that the owner will have potential safety hazards during driving, so don't ignore it.

Introduction to tires

Automobile tires are 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 wheel height and road surface have good adhesion; 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.

The car's tires include spare tires and must be checked regularly every month. During the inspection, it is necessary to observe whether there are any cracks or scratches on the surface of the car tires. It is best to wear gloves and reach to the inside of the tire to check for suspicious marks.

If you find the slightest suspicious point, you should immediately ask the car dealer to do a detailed inspection. Don't be reluctant to throw away faulty tires. If you find that the surface wear of the tire is abnormal, you should think that there may be a problem with the toe-in adjustment of the wheel and need to be repaired.
