Explained: What Sidewall Bulges in Car Tyres Mean and Why They Are Dangerous

Sidewall bulges in car tyres can indicate serious structural problems, often caused by impacts with potholes or driving on underinflated tyres. These bulges form when the internal layers of the tyre are weakened, allowing trapped air to accumulate and create a visible bump. Experts advise not to ignore these signs, as they can lead to complete tyre failure while in motion, resulting in slow leaks or sudden blowouts.
