据了解,我国高速公路发生的交通事故近半数是由于轮胎发生故障引起的,爆胎一项就占轮胎事故总量的70％。如果车辆行驶速度过快,载重量太大,爆胎几乎可以说是致命的。按照国家有关规定,汽车轮胎属于国家强制性安全认证即3C认证的范围,旧轮胎也应该执行此标准,但市场上大量翻新轮胎都没有3C认证。 It is understood that nearly half of the traffic accidents in our country’s expressways are caused by tire failures, and 70% of total tire accidents are caused by flat tire. If the vehicle speed is too fast, too much load, puncture is almost deadly. In accordance with the relevant state regulations, car tires are compulsory national certification that 3C certification range, the old tires should also implement this standard, but the market a large number of retreaded tires have no 3C certification.
