The advantages of the inflate-free hollow tyre are as follows:

1.Good-elasticity: made of Rubber, with high rebound velocity and not creating heat.

2.Well temperature bearing: Can be normal used from 70 to -70.

3. High-resistance: continuous running of 3000 KM, no obviously wears away.

4. Bears the aging: no crack or color changed, aging resistance

5.Lower drive consumes and tiny rolling resistance.
