1. Pneumatic tire
2. Solid tires
3. Polyurethane tire
4. Pneumatic hollow tire
I drew a table about advantages and disadvantages, which is more intuitive.
Comparison of several tire characteristics
1. Pneumatic tire
2. Solid tires
3. Polyurethane tire
4. Pneumatic hollow tire
Mainly made of materials
1. Synthetic rubber, reclaimed rubber, steel wire, curtain, metal valve and valve core.
2. Synthetic rubber and reclaimed rubber
3. Polyurethane
4. Imported natural rubber and synthetic rubber do not need steel cord, which saves a lot of raw materials.
manufacturing process
1. The manufacturing is very complicated and the process is difficult.
2. The process is simple and the working procedure is simplified.
3. The whole foaming process of liquid casting is simplified.
4. Unique patented manufacturing technology

Elastic performance
1 makes good use of compressed air to generate elastic force, with excellent elastic performance.
2 differences
3 Overview
Good rebound rate and good rebound performance.
Weather capacity
Generally, 1 is prone to tire puncture at high temperature and insufficient air pressure at low temperature.
Generally, tires will harden at low temperatures, not to mention elasticity.
3. When the temperature is relatively high, the tire becomes soft, the supporting force and elasticity decrease, and it is easy to be born; Tires will harden at low temperatures.
Very good. It can be used normally at the high temperature of 70℃ to-70℃.
abrasive resistance
1 general
2 poor people
3 Overview
4 Very good. Generally, there is no obvious wear after running for 3000 kilometers continuously, and the wear resistance is good.
aging resistance
General 1 Tires are easy to crack when used for a long time.
2 overview
3 Bad long-term use tires harden until they lose elasticity and are easily punctured by sharp objects.
It's good. Because the materials used are better, the tires will not age and crack after long-term use.
rolling resistance
1 has excellent rolling resistance and can be used on medium-speed and high-speed vehicles.
2 can only be used for low-speed vehicles.
3 Large vehicles can only be used for low-speed vehicles.
Small size can be used for medium and low speed vehicles.
