How do you look at the tire date? How to look at the date of a car tire

Hello! On the outside of the tire, on one side of the tire, there is a set of numbers, from the last four digits of the logo can be known about the date of production, it consists of a total of four digits "aabb". The first two "aa" indicate the weeks of the year, and the last two "bb" indicate the year.

For all tires manufactured after 2000, the last four digits of the tire identification number represent the date the tire was manufactured.

Among these four numbers, the last two digits represent the year of production of the tire, e.g. "XX13" means that the tire was produced in 2013; The first two digits represent the number of weeks the tire was produced, e.g. "3513" means that the tire was produced in the 35th week of 2013.

Hope it helps!

1. The production date of vehicle tires is generally located on the outside of the tire, and the outside of the tire has several important characteristics, for most tires, the outside of the tire will be marked with the English word outside, and the inside of the tire will be indicated with inside; If there are no two words, we can also distinguish by the red solid dot and the yellow hollow dot on the side of the tire, the position of these two points belongs to the outside of the tire.

2. The production date is located on the outside of the tire, and marked with an oval, most of the tire production date is located on the outside of the tire, and is in contact with the tire and the hub of the sub-mouth position, and is marked by an oval symbol. 3. The tire production date is composed of four Arabic numerals, the first two digits represent the year and week of tire production, and the last two numbers represent the year of tire production, such as 2020, which means that the production cycle of this tire is the 20th week of 2020. Tire production cycle is an important factor in judging the quality of tires, the so-called inventory tire refers to the tire of a longer year, this kind of tire after a long period of storage, although it has not been used, but the tire rubber has been aging and cracking, if we buy and use such tires, it is very easy to have a puncture and other dangerous situations, so we must learn how to observe and identify the production cycle of tires.

On one side of the tire, there is a set of numbers on the wall of the tyre, and the last four digits of the logo can be used to indicate the date of manufacture, which consists of the four-digit "AABB". The first two "aa" indicate the weeks of the year, and the last two "bb" indicate the year.

How to look at the model and date of car tires, take you to understand.

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, the following tire, which is a tire on the Passat sedan, has the last four digits of the DOT on the car being 0807, indicating that it was produced in the eighth week of 2007, that is, at the end of February 2007.

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.

Tires are an important part of automobiles, which are cyclic rubber products that are mounted on metal rims. Normally, tires are subjected to various loads and squeezes during driving, which can be called sacrificing themselves to fulfill us.

Hello The 11-digit number and letter immediately after the "dot" letter on the side of the tire indicate the identification number or serial number of the tire, the last four digits of the serial number represent the production date of the tire, and the tire production date ** format: the first two digits represent the weeks of the year, and the last two digits represent the year, such as 1204, which means that it was produced in the 12th week of 04.

How to look at the model and date of car tires, take you to understand.

On the outside of the tire there is a set of numbers representing the date of manufacture, where the first two represent the weeks of the year and the last two represent the year.

Tires are rubber products, which have a lifespan, how to see it, the old hole will take you to understand.

The tire shows its date of manufacture on the sidewall.

On the sidewall of the tire, a combination like 1314 means 14 years and 13 weeks from the factory.

1820 tires are what months are the production dates.

A small square on the side wall is the date of manufacture.

Tires can be regarded as the most worn parts of the car, basically running 5-80,000 kilometers, and they have to be replaced within 5 years, so how to find more than 5 years of gestational age when buying a second-hand car must be paid attention to. The production date of the tire is relatively easy to see, there are 4 numbers in this oval circle, the last two are the year, the first two are the weeks of the year, the above picture shows the 28th week of 2008, that is, around July, so that the production date can be quickly calculated.

The date of the car tire can be found on its side. It is generally a tire series code written according to the date.

The tire is wrapped with a small oval circle with 4 digits, the 4 digits in this circle are the date of production, the first 2 digits are the number of weeks the tire was produced, and the last 2 digits are the year.

In addition to the production date marking, there will be a 185 55 R15 86V logo on the side of the tire, which corresponds to the tire width, aspect ratio, tire type, rim diameter, load-bearing index and speed class marking. 185 means that the tire width is 185mm, 55 means that the tire flat ratio is 55%, r means that the tire is a radial tire, 15 means that the applicable wheel hub is 15 inches, 86 means that the tire load index is 530kg, and V means that the maximum speed that the tire can carry is 240km h.

1. On the outside of the tire, on the tire wall on the outside side of the tire, there is a set of numbers, from the last four digits of the logo can know the information of the production date, it has a total of four digits "AAB" composition. The first two "aa" indicate the weeks of the year, and the last two "bb" indicate the year.

2. For example, the following tire, this is a tire on the car, and the last four digits of the logo dot on the car are 0807, indicating that it was produced in the 8th week of 2007, that is, at the end of February 2007.

3. The following car is a car bought at the end of 2005, in 2006, because the left rear tire was damaged, so a new tire was replaced, and it can be seen from the logo 1606 that its production date was produced in the 16th week of 2006, that is, it was produced in mid-April 2006.

4. The production date of some tires is on the inside of the tire, showing 3907, and the production date is the 39th week of 2007, that is, late September 2007.

5. The following tire is very old from the appearance, and it is produced in the 48th week of 2005 from the sign 4805, which is also produced at the end of November and early December 2005.

6. The following tire is very old from the outside, and it is produced in the 27th week of 2011 from the sign 2711.

How to look at the model and date of car tires, take you to understand.

The tire production lot number is located on the outside edge of the tire.

A set of numbers and letters indicate the date and quantity of tyres. For example, 3907 represents the tire production date in the 39th week of 2007, that is, in late September 2007.

The production lot number is used to identify the age of the tire and how long it has been stored.

Hello dear, the production date of the tire is made up of 4 numbers, which are usually printed on the sidewall of the tire. These numbers indicate the date the tire was manufactured, in weeks and years. For example:

1818, which means that this tire was produced in the 18th week of 2018. Here is the explanation:1

The 1st and 2nd numbers indicate the number of weeks the tires are produced, ranging from 01-52 weeks. 2.The 3rd and 4th digits indicate the year in which the tires were produced.

For example, 1818 means that the tires were produced in 2018. Please note that the life of a tire is limited, regardless of whether the return has been used or not. It is recommended that the tires be replaced after 5-6 years of use.

In addition, if you notice obvious scratches, cracks, abrasion or other damage to the surface of the tire while using it, you should also replace it as soon as possible.

Hello dear, <>

We are glad to answer for you, the tire date is usually expressed in four digits, the first two represent the number of weeks of the production date, and the last two represent the year, such as 3907, which represents the tire production date in the 39th week of 2007, that is, in late September 2007. Tires are ring-shaped elastic rubber products that are grounded and rolled on various vehicles or machinery. In 1845, R.W. Thomson, a Scottish-born civil engineer, invented the pneumatic tyre, and obtained a patent in England with the title of "Improvement of the Wheels of Horse-drawn Carriages and Their Vehicles".

On December 10 of the same year, the first pneumatic tire was born. Tires are usually mounted on metal rims, which can support the body, cushion external shocks, achieve contact with the road surface and ensure the driving performance of the vehicle.

The method of checking the tire date: on the side of the tire (sidewall), the last four digits after the dot represent the production date, and the four digits are composed of the "AAB" format, among them, the first two "aa" indicate the weeks of the year, and the last two "BB" represent the year, there are 52 weeks in a year, according to this rule, you can know the specific production date of the tire.

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 tire is much harder than before, it is likely that the tire has almost aged, especially in hot weather, which will aggravate the hardening of rubber products. When this phenomenon occurs, it is also necessary to answer that the lead must be replaced, otherwise there is a risk of a puncture.

Then, it is certainly not enough to look at the degree of tire aging. Especially for those who use cars regularly, you need to regularly observe the degree of wear and tear of tires, and almost every tire will have a wear mark. Generally, the height of the wear mark on the tire of a passenger car is mm, and the height of the wear mark on the truck tire is mm.

If you find that the wear mark is the same as the tread, it means that the tire is almost worn out and should be replaced in time.
