According to inflation pressure:
① High pressure tires. The inflation pressure is generally more than 5.5 kgf / cm2, with high stiffness and poor cushioning performance, which has been rarely used. ② Low pressure tires. The inflation pressure is generally 2 ~ 5.5 kgf / cm2. With the improvement of cord strength and tire bearing capacity, the inflation pressure of some tires exceeds 5.5 kgf / cm2, but their cushioning performance is close to that of low-pressure tires, which is still low-pressure tires. ③ Ultra low pressure tire. The inflation pressure is generally less than 2 kgf / cm2.
According to tread pattern:
① Ordinary tread tire. There are many styles in vertical, horizontal and two directions. Ordinary transverse tread tires are suitable for poor and gravel roads; Longitudinal tread tires are suitable for use on better roads; Tires with both vertical and horizontal patterns are suitable for general and poor roads. ② Off road tread tires. The tread has a large pattern, which is suitable for mining, construction site, desert, loose soil ground and snow mud road. ③ Mixed tread tire. It is not only suitable for good pavement, but also for gravel pavement and loose soil pavement.
