The pattern design of agricultural tires is a crucial work, which directly affects the traction, stability, wear resistance, heat dissipation and noise level of tires. The following are some tips and techniques for the design of agricultural tire patterns:

First, pattern type selection

Longitudinal pattern: mostly used in car tires, but agricultural tires will also be used according to demand. This pattern has good grip and anti-slip, small rolling resistance, fuel saving, heat dissipation performance is also good. However, it should be noted that the anti-sliding performance is poor, easy to pinch stones and crack.

Horizontal pattern: The pattern is large, the heat dissipation is relatively poor, but the grip is strong. Suitable for occasions requiring greater traction, but the shoulder is prone to crack.

Mixed pattern: between the horizontal pattern and the longitudinal pattern, with the advantages of both. Good anti-slip performance, large adhesion to the ground, not easy to slip, soft tread performance is good, driving should not be empty. But off-road performance is poor, easy to produce uneven wear phenomenon.

Cross-country pattern: suitable for uneven roads, divided into directed pattern and undirected pattern two. The directional pattern has good anti-skid performance and can run on muddy roads; The mud discharge of the undirected pattern is poor.

Second, pattern design details

Depth of pattern: The depth of pattern has an important effect on the traction and wear resistance of the tire. A deeper pattern can provide better traction and self-cleaning, but it will also increase the speed of tire wear. Therefore, it is necessary to choose the appropriate pattern depth according to the operating environment and needs.

Pattern width: The width of the pattern affects the contact area between the tire and the ground, which in turn affects the traction and stability. Wider patterns can provide greater contact area and improve stability, but also increase the rolling resistance of the tire. Therefore, these factors need to be balanced in the design.

Pattern arrangement: The pattern arrangement also affects the performance of the tire. Reasonable pattern arrangement can reduce tire noise level and improve driving comfort. At the same time, the pattern arrangement can be adjusted according to the requirements of the operation to optimize the traction and wear resistance of the tire.

Three, special pattern design

Shoulder pattern: The shoulder pattern refers to the pattern groove near the tire shoulder, and the design is more difficult. In agricultural tires, the design of the shoulder pattern requires special attention to ensure that the tire can maintain good stability and traction when turning and rolling.

Steel sheet design: Because the width of the pattern groove is too narrow, steel sheets will be used as a substitute in the process of tire processing. The steel sheet can not only soften the pattern block, but also reduce the noise. Therefore, the use of steel sheet needs to be reasonably considered in the design of the pattern.

Iv. Other precautions

Heat dissipation performance: The tire will generate a lot of heat during the operation, so the design of the pattern needs to consider heat dissipation performance. Through reasonable pattern design and material selection, the heat dissipation performance of the tire can be improved and the service life can be extended.

Wear resistance: Wear resistance is one of the important performance indicators of agricultural tires. In the design of the pattern, the wear resistance of the tire can be improved by increasing the depth and width of the pattern and optimizing the arrangement of the pattern.

Noise level: Noise level is also one of the important indicators of tire performance. In the pattern design, the tire noise level can be reduced by adjusting the size, shape and arrangement of the pattern block.
