Tyres smashed into a car in a parking lot after falling off a semi-trailer truck in southwestern China.

The dashcam video, filmed in Dali Bai Autonomous Prefecture in Yunnan Province on September 1, shows tyres suddenly coming off a truck driving along a road, colliding with a pickup truck before rolling onto the pavement and bumping into a car in a parking lot.

Fortunately, no one was injured. But two cars were damaged and the loss was over £11,000.

A loose nut caused the tyres to fall off the vehicle and the semi-trailer truck driver was blamed for the incident.

近日，在云南省大理州南涧县境内，一辆半挂车在行车途中轮胎突然飞出，旁边的皮卡车被撞，之后轮胎运动轨迹发生偏移，滚到了路边的停车场内，撞上了一辆小轿车，后车行车记录仪拍下了这一惊魂瞬间。

南涧县公安局交通警察大队民警农康：（前方车辆）车轮与车身分离，后面车轮撞到紧跟在后面与其同向行驶准备超车的一辆皮卡车，轮子与皮卡车相撞之后，轮子轨迹发生偏移，然后继续高速滚动到路边的停车场内，以高速状态撞到了在停车场内停放着的一辆小轿车。

此次事故无人员伤亡，有两辆车受损，损失金额预计超10万元，半挂车驾驶员承担全部责任。车辆使用年限较长致螺丝老化、长期行驶在恶劣路况导致螺母松动都是轮胎脱离的原因，而轮胎脱离会导致很严重的事故。
