Dramatic footage has emerged of a tyre flying out of a trailer driving on motorway leading car crash in China.

In the CCTV video, filmed Yunnan Province last Tuesday, a tyre suddenly flies out of the back of the trailer, when it surpasses a lorry in front.

The tyre flies across the central reservation to the opposite lane. At that time, two cars are coming on the lane. In order to avoid the tyre, the car in front changes direction urgently, thus it loses control and crashes parapet before bumps into central reservation.

According to local reports, car driver moved the tyre to the roadside and drove to a toll station before he called police.

Trailer driver didn't know his spare tyre flied out until police contacted him.

Fortunately, no one was injured.
