Performance Comparison Of Polyurethane Tires And Solid Rubber Tires
At present, solid tires and polyurethane tires (PU) both can be used on many vehicles，such as forklifts, trailers, AGVs, etc.,how should we choose? The following will show you the difference between these two tires.
1. Cushioning performance
The cushioning performance is directly related to the driving comfort and safety of the tire. The higher the hardness, the lower the cushioning performance. The Shore A hardness of rubber tires is usually 67 to 75 degrees (SHORE A), and the hardness of polyurethane tires is often When the temperature is as high as 83 to 95 degrees, due to the high hardness of rigid polyurethane tires, its driving comfort is much worse than that of solid tires. At the same time, due to the impact of hardness, solid tires can be used on rough and uneven roads, while polyurethane tires are Suitable for exercise on the ground of the platform.
2. Load capacity
The load capacity of solid tires is lower than that of polyurethane tires. The load capacity of polyurethane tires is about 1.5-2 times that of solid rubber tires. Of course, the price is also higher than that of solid rubber tires of the same size.
3. Traction performance
Solid tires or polyurethane tires have obvious differences in adhesion to the road. Rubber tires have softer treads, but polyurethane tires are hard. Therefore, rubber tires have a larger ground contact area than polyurethane tires, even with the softest polyurethane tires. In comparison, the traction performance provided by rubber tires also has obvious advantages. In order to improve the traction performance of polyurethane tires, polyurethane tires are usually etched with sipes or different patterns on the tire surface, but even so, the traction performance of polyurethane tires is still not as good as solid rubber tires.
