Bias tire is a tire whose intersection of adjacent plies is less than 90 degrees aligned with the tread centerline. In short, it's a diagonal intersection. The tire has good longitudinal stiffness, strong bearing capacity, but poor comfort, and is suitable for medium speed driving on ordinary roads. Radial tires are now mainstream tires, which means that each layer of the meridian is almost parallel to the section of the outer tire, just like the earth's meridian. The tire has the advantages of fuel saving, wear resistance, long service life, comfort, heat dissipation and large tire thickness. But the manufacturing of radial tire is difficult and the cost is high.

槽的方向与圆周方向相同。此胎面滚动阻力低，不易侧滑，操纵稳定性好，高速性能好，乘坐舒适性好，噪音低。主要适用于路面良好。卡车和公共汽车的前轮通常是这种类型的。这种踏面制动性能及稳定性较差，长时间高负荷行驶时容易出现裂纹，应定期检查。

The groove is in the same direction as the circumference. This tread has low rolling resistance, not easy to sideslip, good handling stability, high-speed performance, good riding comfort and low noise. Mainly suitable for good pavement. The front wheels of trucks and buses are usually of this type. This kind of tread has poor braking performance and stability. It is easy to crack when driving under high load for a long time. It should be checked regularly.

2. 对称

2. Symmetry

以槽为准。左右两侧花纹相同或相似，或另一侧旋转180度后完全重叠。这种轮胎具有良好的静音舒适性，因为它降低了轮胎的滚动阻力，非常省油，所以经济型耐磨轮胎就是这样设计的。

The center groove shall prevail. The patterns on the left and right sides are the same or similar, or the other side is rotated 180 degrees and overlapped completely. This kind of tire has a good quiet comfort, because it reduces the rolling resistance of the tire, very fuel-efficient, so the economic wear-resistant tire is designed in this way.

3.肿块

3. Mass

这些凹槽相互连接，呈现出一个独立的图案结构。该胎面轮胎具有优越的制动和操纵性能，尤其是在雪地和潮湿的路面上，其排水性能非常好，所以雪地轮胎和商用车后轮都是该胎面轮胎。但这种独立的模式块结构导致了较差的耐磨性。

These grooves are connected to each other and present an independent pattern structure. The tread tire has excellent braking and handling performance, especially in snow and wet road, its drainage performance is very good, so the snow tire and the rear wheel of commercial vehicles are the tread tire. However, this independent pattern block structure leads to poor wear resistance.

4. 单方向

4. Single direction

这些凹槽相互连接，呈现出独立的图案块状结构。该模式方向性明显，块度较大，横切方式较少，具有阻力小、速度快、控制性能好等特点，适用于高速驾驶。但这些轮胎有噪声，仅适用于运动轮胎，且必须安装在与行驶方向相同的方向上。

These grooves are connected to each other, presenting an independent pattern block structure. This mode has obvious directionality, large block size, less crosscutting mode, small resistance, fast speed, good control performance, and is suitable for high-speed driving. However, these tyres are noisy, only suitable for sports tyres, and must be installed in the same direction as the driving direction.
