What are the characteristics of the various tread patterns of tires

Jan 05,2019

The tread portion of a tire is inlaid with a variety of grooves, which is called the tread pattern, and there are four basic tread patterns and features. The tread pattern of a general automobile tire is made by freely combining these basic patterns and adding many new design concepts.

Type Longitudinal pattern Transverse pattern Mixed pattern Off-road pattern

Tread pattern

Shape Patterns spread out and joined together (longitudinal pattern) Patterns cut horizontally (transversal pattern) Patterns combining transversal and longitudinal patterns Patterns made up of separate blocks

Characteristics 1. Good handling stability. 2.

2. Low rolling resistance.

3. Low noise.

4. good drainage

5. Anti-skid and excellent steering stability.

1. Excellent driving and braking power. 2.

2. strong traction.

3. Excellent resistance to puncture matting.

1. longitudinal stripes provide steering stability and help prevent sideslip. 2.

2. cross grain improves driveability, braking power and traction.

1. excellent driving and braking power. 2.

2. good steering stability in snow and slush.

Tire Tread Selection

1. should be based on the vehicle purpose often used road conditions and speed to choose a more appropriate pattern tires. For the general hard surface of the vehicle driving at moderate speeds, trucks and buses, such as the appropriate choice of transverse pattern or longitudinal and transverse pattern tires; for often in the highway and good hard surface vehicles should be selected on the vehicle with good heat dissipation, transverse stability of strong longitudinal and transverse pattern and longitudinal and transverse pattern tires.

2. With the increase in speed, the tread and the road between the water can not be excluded in time will be formed between the two sides of the water film, the tire slowly up, under certain conditions and even completely off the road, so that the car completely lost maneuverability. This phenomenon is called tire "water skiing phenomenon". Affect the critical speed of water skiing more factors, but one of the tire pattern type and convinced that the ballet is one of the main factors. Often driving on the highway car, under the condition, should try to choose anti-skid tires (Figure 5). The main feature of this pattern is, in the middle of the tread design a wide drainage groove (main groove), between the tire and the road to form a larger drainage space. In the main ditch two have to the side of the tire side ditch, so the drainage distance is short, high drainage efficiency, thus maximizing the feed tires in the wet road at high speed may produce "water sliding phenomenon", improve the safety of driving.

It is worth noting that this pattern has directionality, do not be careless when installing.

3. The direction of rotation of the patterned tires is usually indicated by an "arrow" molded on the sidewall. If the tire is rotated in the direction of the arrow, i.e., the tip of the "herringbone" pattern hits the ground first, the tire is said to be rotated in the right direction; if it is rotated in the opposite direction, the tire is said to be rotated in the opposite direction.

Anti-slip tires are always placed in the smooth direction to improve drainage efficiency, while reverse placement is less efficient than non-slip tires.

Cross-country treaded tires, if installed on the drive axle, should be rotated in the direction of the "herringbone" pattern tip like a chain embedded in the slush, grip ability, and embedded in the grooves of the pattern of the slush can be squeezed from both sides, the pattern has a self-cleaning; if installed in the slave axle on the cross-country treaded tires, due to the non-output traction In order to reduce rolling resistance and wear and tear, it should be rotated in the opposite direction.

In summary, tire tread is an important part of improving automotive performance and ensuring driving safety. Therefore, how to correctly purchase, install and use tire tread is very important.
