This is the heartstopping moment a pedestrian was just moments away from being knocked out by a flying wheel.

The elderly woman was walking to the market when a boat trailer's wheel came loose on the highway next to her in Bangkok, Thailand on February 22.

CCTV video footage from a nearby shop captured how the loose wheel bounced across four lanes as it came flying towards her.

She appeared to hear the heavy tire bouncing her way so she stopped and turned around - narrowly avoiding walking into the path of the object.

The woman was unhurt and the loose wheel slammed into the wall of a nearby shop

Shop owner Sirawit Piyajinda said: 'We heard a loud crash outside and saw the wheel. The old woman was also outside looking terrified.

'We watched what happened afterwards. We were relieved no one was hurt.'

Sirawit added that the driver who owned the wheel returned later that day to retrieve the object. He said: 'The owner of the tire went to us that day to take it away. He apologised and offered to pay for any damage.'

The woman was unhurt by the incident and there was damage to properties. However, the shop owner advised the driver to be more careful next time.
