Where to see the production date of car tires?

The 11-digit number and letters next to each other indicate the identification number or serial number of the tire, and the last four digits of the serial number represent the date the tire was manufactured. It consists of a four-digit "aabb". The first two "aa" indicate the weeks of the year, and the last two "bb" indicate the year.

Tire production date** format: the first two digits indicate the production week, and the last two digits indicate the year of production, e.g. 1204 indicates that it was produced in the 12th week of 04. Tires are ring-shaped elastic rubber products that are grounded and rolled on various vehicles or machinery.

It is usually installed on a metal rim, which can support the body, cushion external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle.

Tires are often used under complex and harsh conditions, and they bear various deformations, loads, forces, and high and low temperatures when driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, high abrasion resistance and flexural resistance, as well as low rolling resistance and heat generation are required. Half of the world's rubber consumption is used in tire production, which shows the ability of tires to consume rubber.

The production date of the vehicle tire can generally be seen in the sidewall position of the vehicle, and you will see that there are 4 digits after the three letters dot in the sidewall position of the tire, the first two digits represent the number of weeks the tire was produced, and the last two digits represent the year of production of the tire.

For the production date of the tire, you can find that on the tire wall on the outside of the tire, there is a set of numbers, from the last four digits of the sign can know the information of the production date, this set of numbers is very important, for example, the number of the tire is 0807, then the production date of this tire is the 8th week of 07 years of production.

In this issue, we will share with you how to look at the production date of car tires, read it in one minute, and you will never be afraid of being fooled when you buy car tires, let's take a look.

Checking the production date of tires is actually relatively simple. First, we need to find the DOT on the sidewall, and then we can see the date the tire was made from the last four digits of the DOT. These four digits are in the form of "aabb", where "aa" indicates the week of the corresponding year, and "bb" represents the year of production.

For reference, the car tire date** below is followed by "3513", indicating that the tire was manufactured in week 35 of 2013. When the production date cannot be found behind the DOT, it is possible to be on the other side of the tire; And if you can't find the dot, it may be that the tire is installed in reverse, and the production date is installed on the inside of the tire, so you can't see it. Generally, the service life of tires is 3-5 years.

However, it is too hasty to determine the service life of tires based on the production date alone, and some real conditions of tires should be combined. First of all, the most obvious phenomenon is the appearance of many small cracks, which we can also call tire cracks.

Not only does the comfort of the tires have an impact, but it will also cause the grip of the tires to deteriorate seriously, so there is a certain danger when driving. Therefore, we must not have a fluke mentality, and should replace it in time.

Secondly, if you feel that the tires are much harder than before, it is likely that the tires have almost aged, especially in hot weather, which will aggravate the hardening of rubber products. When this phenomenon occurs, it also needs to be replaced, otherwise there is a risk of a puncture.

For all tires manufactured after 2000, the last four digits of the Tire Identification Number (TIN) represent the date the tire was manufactured. Of these four numbers, the last two digits represent the year the tire was produced, for example, "XX13" means that the tire was produced in 2013; The first two digits represent the number of weeks the tire was produced, such as "3513", which means that the tire was produced in the 35th week of 2013.

For example, the tire below shows 4117 with a production date of week 41 of 2017. Is it easy to identify?

Hello, glad to answer for you. Generally, the production date of tires is on the side of the tire! The first 2 digits are the weeks the tires were produced, and the last 2 digits are the year.

The following is a specific introduction to the tire parameter specifications: 1. Take 195 55 R1685V as an example: (1) 195:

Refers to a tire width of 195mm. (2) 55: refers to the flat ratio of the tire, that is, the cross-sectional height is 55% of the width.

3) R: refers to the tire is a radial tire (the inner layer of this tire is a radial tire manufacturing method). （4）15：

Refers to the rim diameter is 15 inches. (5) 85: The load index 85 represents the maximum load-bearing capacity of 515 kg, and the four tires are 515 4 = 2060 kg.

6) V: refers to the speed level of 240 km/h.

1. There is a set of numbers on the outside of the tire wall to represent the production date, where the first two represent the weeks of the year, and the last two represent the year.

2. For example, a tire on a car, the four digits in the oval frame are 0715, indicating that it was produced in the seventh week of 2015, that is, the tire produced in late March 2015.

3. The rubber of the tire has a life, so to avoid spending money to buy a backlog of tires, you must first look at the production date of the tire when buying a tire.

The production date of the tire is indicated by four digits, these four digits are written on the side of the tire, the first 2 digits are the number of weeks the tire was produced, and the last 2 digits are the year. For example, the four-digit number of 1019 means that the tires were produced in the 10th week of 2019. Usually, when buying tires, you must look at the production date, and if the production date is a long time ago, do not buy it.

Tires are rubber products, and even if they are not used, they will deteriorate. When using the car, you need to check the tire pressure and tire surface frequently for damage. The sidewall of a tire is fragile and cannot be repaired if it is scratched or punctured.

It is recommended that car owners change their tires every four years, even if they have driven less mileage in four years.

The production date of the vehicle tire is generally on the side of the tire, and you can see on the side of the tire, there are 4 digits after the three letters of dot, the first two digits represent the number of weeks the tire was produced, and the last two digits represent the year of production of the tire.

The DOT logo is usually molded on one side of the tire, and the last four digits of the mark can be used to indicate the date of manufacture, which consists of four digits "AAB". The first two "aa" indicate the weeks of the year, and the last two "bb" indicate the year.

For example, this is the tire of the Passat sedan. The last four numbers on the DOT on the Passat sedan are 0807, indicating that it was produced in the eighth week of 2007, at the end of February 2007.

Notes:

The direction of the radial cord layout is consistent with the radial section of the tire, and its cord layer is equivalent to the basic skeleton of the tire. In order to ensure the stability of the rope, there are several layers of belt layer (also known as lashing layer) made of high-strength and non-stretching materials outside the rope. The direction of the rope has a large angle to the meridian section.

From a design point of view, deviation tires have many limitations, such as due to strong cross rope friction, so the body of the tire heats up easily, so it accelerates tread wear, and the rope layout is not very good to provide excellent handling and comfort.

The steel ribbon of radial tires has better flexibility, adapts to the effects of irregularities, and is durable, and its organizational structure also means that there is less friction than the diagonal on the car, extending the life of the tires and thus obtaining better fuel economy.

The tire production date is marked with four digits on the side of the tire, and the first two digits represent the week; The last two digits represent the year.

The production date of the tire can be seen through the sidewall identification of the tire, and the last four digits of the letter dot are the production date of the tire. The first two digits of the sidewall marking of a tyre indicate the week of the year, and the last two digits indicate the year. The production date of the tire cannot be more than 3 years, because the main raw material of the tire is rubber, the 3-year-old tire has been aged, and there will be safety hazards in the use of aging tires.

Although tires have a certain shelf life, but unlike food marked with shelf life, it has a lot to do with the actual use, if there is no bad driving habits, the service life of tires is 3 to 5 years. Regular maintenance of your tires can help extend the life of your tires.

The production date of most brands can be seen directly on the outside of the tire. If you can't find the production date on the tire, you can install the tire upside down.

Single-tire performance tests are carried out in order to study the performance of tire monomers or the performance of tires assembled into the whole vehicle: static ground pressure distribution, rolling resistance, tire rigidity, tire cell noise, tire modality, PRAT, six-component force test, odor performance, air tightness, environmental protection, tire dynamic balance uniformity, etc.

Tire performance. As the only part of the car in contact with the ground, the performance of the tire directly affects the safety of the driver and passengers of the vehicle, and the importance of tire performance can be imagined.

With the rapid development of the automotive industry, consumers have begun to pay attention to the comfort, handling stability, NVH and other performance of the vehicle in addition to the safety performance of tires.

Single-tire performance tests are carried out in order to study the performance of tire monomers or the performance of tires assembled into the whole vehicle: static ground pressure distribution, rolling resistance, tire rigidity, tire cell noise, tire modality, PRAT, six-component force test, odor performance, air tightness, environmental protection, tire dynamic balance uniformity, etc.

On the side of the tire there is a set of 4 digits, which represents the date the tire was manufactured. The last 2 digits of this set of numbers indicate the year, and the first 2 digits indicate the weeks of the year. For example:

4919 indicates that it was produced in the 49th week of 2019.

1. The tire date is consistent: the production date of the four tires on the car should be the same, and there is not much difference with the factory time of the car. If a tire is inconsistent with the others, it means that the tire has been replaced; If there is too much difference between all the tires and the time when the car left the factory, it means that all the tires have been replaced.

2. The production date is printed on the side of the tire: each tire is printed with the production date, which will be displayed on the side of the tire, and you can check it yourself. This can be known by looking at the letters and numbers on the side of the tire, and from the last four digits you can know the date of manufacture of this tire.

For all tires manufactured after 2000, the last four digits of the tire identification number (TIN) represent the date the tire was manufactured. 3. The shelf life of the tire.

The shelf life of general car tires is three years, because tires are mainly made of rubber, and the shelf life of rubber is three years, so the replacement cycle of tires should be once every three years. Therefore, when buying, be sure to choose tires with the closest production date.

The production date of the vehicle tire is generally on the side of the tire, you can see on the side of the tire, there are 4 digits behind the three letters of dot, the first two digits of the chain watch are the weeks of production of the tire, and the two digits of the rear mountain represent the production year of the tire.

Find the date of manufacture on the side of the tire, which is usually in the form of a four-digit number. A series of alphanumeric numbers starting with dot, and the last four digits are the production date, the first two digits represent the production cycle, and the last two represent the production year.

The parameters of the tire generally include the flat ratio, load index, maximum speed, etc., which are expressed in numbers and letters, and are usually seen on the outside of the car tire. For example, the parameters of a car tire are 195 65 r15 91h, then its specific meaning is as follows:

Indicates that the width of this tire is 195mm;

It means that the flat ratio of the tire is 65, and the filial piety of the flat ratio means that the height of the tire is divided by the width;

3. R: means that the tire belongs to the radial tire;

Indicates that the rim diameter of this tire is 15 inches;

It means that the load index of the tire is 91, which corresponds to 615kg, and the total of the four tires reaches 2460kg;

6. H: It means that the maximum speed that the wheel can withstand is 210km/h.

For the date ballast core, take the following car tire production date **dot 51 k3 v592 3617 as an example, where 3617 represents the production date of the 36th week of 2017.

How to protect car tires?

Our car owners should check the condition of the wheels before using the car on a daily basis, and avoid using the vehicle when the wheels are found to be bulging and leaking, so as to avoid tire bursts and skidding during driving, which poses a greater threat to the safety of the people on the car. And the owner should pay more attention to the maintenance of car tires and clean them up in time.
