Where is the tire label Top 19U LMBTAO 1120 made?

Tires are an important part of cars. There are more than 10 kinds of markings on car tires. Correct identification of these marks is very important for tire selection, use and maintenance. It is also important for ensuring driving safety and extending tire service life. of great significance.

Tire specifications

Tire specifications: Specifications are symbolic data of tire geometric parameters and physical properties. Tire specifications are often represented by a set of numbers. The first number indicates the tire section width, and the latter number indicates the rim diameter, both in inches. The letters or symbols in the middle have special meanings:

Tire structure: "R" means radial tires, "D" and "一" mean bias tires.

Others: "XL" means The texture is partially reinforced tires, "TG" means engineering tractors and grade machine tires (off-road use), "NHS" means off-road use tires

Layer: The tier is. It refers to the nominal number of ply layers in the tire rubber layer, which is not completely consistent with the actual number of ply layers. It is an important indicator of tire strength. The layers are marked in Chinese, such as 12 layers; in English, such as "14P. R″ means 14 layers.

Cord material

Cord material: Some tires are marked separately, such as “nylon” (NYLON), which is usually marked after the layer; The tire manufacturer is marked with the first letter of Chinese pinyin after the specification, such as 9.00-20N, 7.50-20G, etc. N means nylon, G means steel wire, M means cotton, and R means rayon.

Load and air pressure

Load and air pressure: Generally, the maximum load and corresponding air pressure are marked. The load is in "kg", and the air pressure is the tire pressure in "kilopascals".

Rim specification

Rim specification: Indicates the rim specification that matches the tire. For practical use, such as "standard rim 5.00F"

Balance mark

Balance mark: Made of colored rubber in the shape of a mark, printed on the sidewall, indicating that the tire is the lightest here. It should be facing the valve when assembled to ensure the balance of the entire tire.

Rolling direction

Rolling direction: The pattern on the tire is particularly critical for water drainage and anti-skid during driving. Therefore, off-road vehicle tires with asymmetric patterns are often assembled with arrows to mark the rolling direction to ensure the design's adhesion, anti-skid and other properties. If installed incorrectly. , it is counterproductive.

Wear limit mark

Wear limit mark: Rubber strips and blocks are used on the side of the tire to mark the wear limit of the tire. Once the tire wear reaches this mark, it should be replaced in time. , otherwise the tire will burst midway due to insufficient strength.

Production batch number

Production batch number: Use a set of numbers and letters to indicate the year, month and quantity of the tire, such as "98N08B5820". Indicates the 5820th tire produced by Group B in August 1998. The production batch number is used to identify the condition and storage time of the tire.

Trademark: The trademark belongs to the tire manufacturer. Logo, including trademark text and pattern, is generally prominent and eye-catching and easy to identify.

Other marks: such as product grade and production. License numbers and other ancillary marks can be used as reference materials and information when choosing.

Tire markings are generally relatively standardized, and you can purchase and use them with confidence after they are clearly identified.

The following is a common way to express tire specifications:

Example: 185/70R1486H

185: Tread width (mm)

70: Aspect ratio (tire height ÷ tire width)

R: Radial structure

14: Steel rim diameter (inches)

86: Load index ( Indicates that the corresponding maximum load is 530 kg)

H: Speed ??code (indicates that the maximum safe speed is 210 km/h)

Speed ??code maximum speed (km/h)

C:60 D: 65 E:70 F:80 G:90 J:100 K:110 L:120 M:130 N:140 P:150 Q:160 R:170 S:180 T:190 U :200 H:210 V:240 W:270 Y:300
