Tyre Sidewall Bulge — Why It's Dangerous and What to Do

A bulge in your tyre sidewall means the internal structure is broken. It can blow out at any time — here's what to do.

Tyre Sidewall Bulge — Why It's Dangerous and What to Do

轮胎侧面出现鼓包(bulge/bubble),是很多车主容易忽略但其实非常危险的状况。

鼓包是怎么形成的?

轮胎内部由多层帘布(钢丝/尼龙层)构成,提供结构强度。

撞到坑洞、上坎过快、或轮胎气压过低时,这些内层结构可能断裂。

断裂处气压从内层穿透到外层橡胶,形成鼓包。

能继续开吗?

不能。鼓包代表轮胎结构已损伤,随时可能在行驶中爆胎,尤其高速时非常危险。

没有任何修补方法能修复鼓包——唯一的处理方式是更换轮胎。

发现鼓包怎么办?

立即降速,避免高速行驶。

尽量减少急刹、急转弯。

尽快来店更换——别拖,鼓包随时可能爆。

同时检查其他三条轮胎,撞坑洞通常对多条轮胎都有影响。

结论

发现鼓包当天就该换,不能等。4M CARCARE 提供轮胎检查与更换,各品牌轮胎都有,来店报价。
