Solid tire manufacturers talk about the difference between polyurethane and rubber tires
Performance comparison between polyurethane and rubber tires:
Buffer performance
The capacity of the buffered tire is directly related to its hardness. The higher the hardness value, the more difficult the tire is. The industrial solid tire reduces the ability to absorb impact energy, and the buffering performance deteriorates. When the hardness of the rubber tire is usually 67 to 75 degrees, and the hardness of the polyurethane tire is often as high as 83 to 95 degrees, the riding quality of the rigid polyurethane tire is far better than that of the rubber tire in the automatic loading driver of the vehicle. When riding comfort is a very important measure, wearing rubber tires will improve.

Traction performance
The adhesion between solid or polyurethane tires and the road surface is significantly different The rubber tire tread is soft, but the polyurethane tire is hard, so the rubber tire has a larger ground impression area than the polyurethane tire. Even compared with the soft polyurethane tire, the traction performance provided by the rubber tire has obvious advantages. In order to improve the traction performance of polyurethane tires, polyurethane tires are usually etched with knife grooves or different patterns on the surface of the tires, which not only improves the traction performance, but also does not lose the high bearing capacity of the tires.
carrying capacity
The bearing capacity of polyurethane tires is about twice that of rubber tires, which is why manufacturers of automatic loading vehicles usually use polyurethane tires on the load axle. Polyurethane tires have excellent crack growth resistance, tear resistance and collapse resistance, while rubber tires are often damaged early due to these problems. As the carrying capacity and speed of all kinds of automatic loading vehicles continue to improve, whether rubber tires or polyurethane tires, the early damage caused by continuous overload driving has become the main phenomenon of tire failure, "overload=heat=failure", and the use of polyurethane tires and rubber tires is also the same.
