<p>This invention relates to a combination of multiple tires disposed adjacently parallel to each other on a single wheel, respective inner spaces of the multiple tires being communicated with each other by way of an airflow piping. The airflow piping comprises a pneumatic pressure control valve which can be opened or closed due to an air-leaking condition of the multiple tires. When one of the multiple tires leaks air rapidly, the pneumatic pressure of the other normal tire is also decreased, thereby allowing the driver to notice the puncture. If the former leaks air slowly, its air is supplied by the latter, respective pneumatic pressures are going to become equal, thereby the driver can drive for a certain time and be free from any serious accident that may occur when he is unaware of the puncture.</p> |
