How does solid rubber tire prevent severe sidewall friction and dry cracking?

Solid rubber tire is a type of tire that does not contain gas and is mainly made of rubber material. The characteristic of solid rubber tires is that they do not cause tire pressure loss or flat tires, and can withstand high speeds and heavy loads over short distances. Compared to pneumatic tires, solid rubber tires have higher wear resistance and puncture resistance. Solid rubber tires are used in special occasions such as forklifts, hand carts, and industrial equipment.

Solid rubber tires are designed and manufactured through a series of measures to prevent severe sidewall friction and dry cracking. Here are some common methods:

1. Material selection: solid rubber tires usually use good rubber materials, which have high wear resistance and aging resistance. Rubber materials can be formulated according to actual needs, and reinforcing agents and fillers can be added to improve the performance of the material. For example, adding anti-aging agents can delay the aging process of rubber materials, thereby reducing the risk of drying and cracking.

2. Sidewall design: Solid rubber tires usually have a raised design on the sidewall, which can reduce direct contact between the sidewall and the ground, thereby reducing the occurrence of friction. The design of raised sidewalls can also increase the stability and load-bearing capacity of the tire, and improve the overall wear resistance.

3. Reinforced structure: During the manufacturing process of solid rubber tires, a fiber reinforced material such as nylon or steel wire is added to increase the tire's strength and rigidity. This fiber reinforced material can effectively prevent tire deformation during heavy loads or high-speed driving, thereby reducing the risk of sidewall friction.

4. Use of lubricants: During the use of solid rubber tires, some lubricants can be used to reduce friction between the sidewall and the ground. These lubricants can reduce heat generation and provide a smoother driving experience, thereby reducing the risk of severe sidewall friction. The use of lubricants needs to be selected and operated according to specific circumstances.

5. Good use and maintenance: Solid rubber tires need to pay attention to reducing violent braking and sharp turns during use to reduce the occurrence of sidewall friction. In addition, regular inspection and maintenance of tires are also very important, including checking the degree of wear, cracks, and smoothness of the tire surface. Reasonable use and maintenance can prolong the service life of solid rubber tires and reduce the occurrence of problems.

In summary, solid rubber tires prevent severe sidewall friction and dry cracking through measures such as material selection, sidewall design, structural strengthening, lubricant use, and reasonable use and maintenance. These measures can improve the performance and safety of solid rubber tires, thereby meeting the needs of different occasions.
