Post: Tire logo description

Tires are the most important parts of a car. Although they are small, they play a very important role. The specifications and sizes of the tires are marked on the sidewalls of each tire. Are the larger the values, the better? Of course not. Let’s take a look at the specifications of the tires.
Among them, the values ​​before /, taking the above picture as an example, 215 refers to the tread width, the unit is mm (millimeter). The wider the tread width of the tire, the more comfortable it will be during driving, the stronger the grip will be, and it will help improve the performance when cornering. But there are also disadvantages, such as greater tire noise and increased fuel consumption. The larger the tread width, the larger the contact area between the tire and the ground, the greater the friction between the tire and the ground, and the higher the safety performance of the tire. /The value after, taking the above picture as an example, 55 is the aspect ratio of the tire, that is, the ratio of the tire sidewall height to the tread width. The larger the aspect ratio of the tire, the stronger the buffering capacity of the vehicle and the better the comfort.
R is the abbreviation of Radial in English, indicating that the tire is a radial layer structure, that is, a radial tire. RADIAL TUBELESS/TUBELESS RADIAL means tubeless radial tire. This type of tire is characterized by high precision, light weight, good balance, more comfortable ride, wear resistance, long service life and high safety factor.
The load index is the value of the maximum load that a tire can bear under specified conditions at the maximum air pressure. The larger the load index, the greater the pressure that the tire can bear, but this value is not necessarily better, because the greater the load, the stronger the pressure bearing capacity of the tire is required, the higher the requirements in terms of raw materials, structure, etc., and the higher the corresponding manufacturing cost. Generally, tires with a large load index are suitable for special types of engineering vehicles.
The speed level refers to the maximum speed allowed for the tire under the load capacity corresponding to the relevant load index. The speed levels H and V, Y of general passenger cars can be applied to sports cars.
UTQG logo, 3T index——
TREADWEAR320: wear resistance index, indicating that the wear resistance index of the tire is 320. The larger the value, the more wear-resistant it is, and the longer the service life of the tire;
TRACTION AA: grip index, AA level indicates that the grip is very good, and the braking performance and acceleration performance are excellent;
TEMPERATURE A: temperature index, A level indicates that the tire has the highest level of high temperature resistance, and such tire structure has good stability.
INSIDE represents the inside of the tire, and OUTSIDE represents the outside of the tire. When installing the tire, you must pay attention to the inside and outside of the tire.
The English part of the three values ​​connected by two plus signs is the structure of the tire. The more layers here, the thicker the tire wall, the better some of the tire’s performance, and the more wear-resistant it is. But too many layers will make the tire bulky. The series of English words after SAFETY WARNING are the safety warnings of the tire.
DOT stands for American traffic certification; TC3L is the origin information; JATR is the factory code. In addition to DOT, there are some certification marks from other countries, such as China CCC safety certification mark, GOST Russian certification, SABS South African certification, E.C.E United Nations Economic Commission for Europe automotive regulations, BIS Indian certification, INMETRO Brazilian certification, NOM Mexican certification, SASO Saudi certification, SNI Indonesian certification, etc.
