Knowledge of tire pattern
1. Low longitudinal pattern resistance and high speed, suitable for cement, asphalt and other roads.
2. The horizontal pattern has strong grip and good climbing performance, and is suitable for general roads.
3. The hybrid pattern combines the characteristics of longitudinal patterns and horizontal patterns, and is suitable for a variety of road surfaces.
4. The off-road pattern is suitable for roads with no road surface or poor conditions.
5. When the tread pattern is worn to the wear mark, stop using it.
Precautions for tire pressure
1. The tire should be inflated according to the "air pressure load correspondence table" specified in the current national standard.
2. After the tire is inflated, each part should be checked for air leakage. If the air leakage is found, it should be repaired in time.
3. The tire must ensure normal internal pressure during use. When running or working for a long time, the tire pressure should be checked regularly; when parking for a long time, the front and rear axles must be erected.
4. If the pressure is too high, the tire is easy to wear crown and crown burst; if the air pressure is low, the tire is easily deformed and crushed.
5. When the tires are installed together, the inflation of the two tires is the same, not one air pressure is high, the other is low.
6. The tolerance range of air pressure shall conform to the following requirements:
Tolerance range of using air pressure:
Tire type tolerance
Car tire plus or minus 10kpa
Truck tires plus or minus 20kpa
Construction machinery tires plus or minus 30kpa
Tire application guide
When matching a new car, the same vehicle should be equipped with the same brand tire; when replacing the tire, strive to install the same brand, specification, level, and pattern of tires on the same axis; mixed assembly of diagonal tires and radial structures is not allowed.

When installing directional pattern tires, pay attention to the direction of rotation indicated by the arrow mark on the sidewall. If you often drive on hard roads, the tires of the driven wheels (such as the tires on the front axle or trailer axle) are installed in the opposite direction, and the road is not used. Or field work, it is not necessary to install in the opposite direction (front axle tires installed in the opposite direction).
The load (L) capacity of the tire is proportional to the 0.585 power of the inflation pressure (P). The high air pressure load is large and the low air pressure load is small. Within the safe range, when the air pressure increases or decreases by 10%, the load increases or decreases by 5% accordingly. The user can adjust the air pressure to the pressure corresponding to the load according to the loading speed of the vehicle. Under special circumstances (such as deserts and swamps), it is allowed to lower the air pressure, lower the specific pressure, and strengthen the passing ability. Air pressure decreases, load capacity decreases, and service life declines. The low-speed driving can increase the tire load accordingly. When the twins are installed, the air pressure of the twins
Try to be equal, otherwise, the load will easily increase to the higher pressure tires, resulting in artificial overload. However, if you often drive on a road with a large degree of arch, the outer tire pressure may be 20Kpa higher than the inner tire pressure.
Vehicle or machine, the speed of transportation or operation is related to the load capacity of the tire; when the air pressure is constant, the speed decreases and the load increases, the speed increases and the load decreases /h and 50Km/h. If you are basically driving on the road, you can increase the load of the tires and increase the air pressure accordingly.
For every 5000km (or about 200 hours of operation), if conditions permit, the tires will be adjusted according to the secondary maintenance of the vehicle. Adjusting the surface and changing the persistence, the wear of each tire is kept uniform and equal to each other, which is an effective way to promote the replacement of the tires of the entire vehicle to improve the service life. Tire cross transposition method.
