The difference between solid tires and polyurethane tires

The difference between solid tires and polyurethane tires is mainly reflected in the following aspects:

  1. Buffering performance

The quality of the cushioning performance is directly related to the driving comfort and safety of the tire. The harder the tire, the worse the cushioning performance. The hardness of rubber tires is usually 67-75 degrees (Shore a), and the hardness of polyurethane tires is usually 83-95 degrees. Due to the higher hardness of rigid polyurethane tires, its driving comfort is much worse than that of solid tires. At the same time, due to the high hardness, solid tires can be used on rugged roads, polyurethane tires, on the other hand, suitable for platform ground use.

  1. Carrying capacity

Polyurethane is used to analyze and compare the load-carrying management capacity of tires and solid tires. The load-carrying capacity of solid tires is relatively higher. Polyurethane tires are lower. The load-carrying development capacity of polyurethane tires is about 1.5-2 times that of solid tires. Of course, the price A solid tire of the same size is much higher.

  1. Traction performance

The adhesion of solid tires or polyurethane tires in contact with the road surface is significantly different. Rubber tires have softer treads, while polyurethane tires are harder, so the ground contact area of ​​rubber tires is larger than that of polyurethane tires. Even when compared with softer polyurethane tires, rubber tires have obvious advantages in traction performance. In order to improve the performance of the traction system of the company’s polyurethane tires, polyurethane tires usually have sipes or patterns of different development forms on the tire surface, but even if we do, the traction performance of polyurethane tires is still not as good as solid tires.
