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.

槽的方向與圓周方向相同。此胎面滾動阻力低，不易側(cè)滑，操縱穩(wěn)定性好，高速性能好，乘坐舒適性好，噪音低。主要適用于路面良好。卡車和公共汽車的前輪通常是這種類型的。這種踏面制動性能及穩(wěn)定性較差，長時間高負荷行駛時容易出現(xiàn)裂紋，應定期檢查。

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. 對稱

2. Symmetry

以槽為準。左右兩側(cè)花紋相同或相似，或另一側(cè)旋轉(zhuǎn)180度后完全重疊。這種輪胎具有良好的靜音舒適性，因為它降低了輪胎的滾動阻力，非常省油，所以經(jīng)濟型耐磨輪胎就是這樣設計的。

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.

這些凹槽相互連接，呈現(xiàn)出一個獨立的圖案結(jié)構(gòu)。該胎面輪胎具有優(yōu)越的制動和操縱性能，尤其是在雪地和潮濕的路面上，其排水性能非常好，所以雪地輪胎和商用車后輪都是該胎面輪胎。但這種獨立的模式塊結(jié)構(gòu)導致了較差的耐磨性。

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. 單方向

4. Single direction

這些凹槽相互連接，呈現(xiàn)出獨立的圖案塊狀結(jié)構(gòu)。該模式方向性明顯，塊度較大，橫切方式較少，具有阻力小、速度快、控制性能好等特點，適用于高速駕駛。但這些輪胎有噪聲，僅適用于運動輪胎，且必須安裝在與行駛方向相同的方向上。

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.
