The tire comprises a tire cavity and first and second side walls. The cyclic type pneumatic tube is connected with the tire and forms a cyclic type air passage. The inlet device is located in the cyclic type air passage and operates to make the air pass through the cyclic type air passage. The outlet device operates the open location to make the air, which is pumped along the cyclic type air passage, pass through a tire cavity. |
