The tire pattern relates to traction, braking, wear resistance, water drainage, noise reduction and other properties. When designing the tread pattern of the truck tire, the factors such as road condition, load capacity, running speed, climate condition and the like are usually considered. In general, the longitudinal pattern has good guiding and drainage performance, low noise in high-speed running and small rolling resistance, the transverse pattern has better driving performance and braking performance than the longitudinal pattern, but the lateral sliding performance is larger than the longitudinal pattern, the noise is high, the rolling resistance is large, the block pattern has the best dynamic performance, the tire patterns are arranged in blocks, and when the vehicle runs on snowy or muddy ground, the patterns are deeply embedded into the snowy or muddy ground, so that the vehicle generates driving force.
