Have you ever wondered what those strange bumps on your car tyre actually mean, and whether they should worry you?
🇰🇪 Breaking It Down
Many motorists notice odd bulges or bubbles on their tyre sidewalls but brush them off as harmless, not knowing they could be a warning sign.
Tyre experts say these bulges are different from the small dents or wavy lines that naturally appear during the manufacturing process.
While minor indentations are considered normal, a raised bubble pushing outward from the sidewall points to a much deeper structural problem within the tyre.
📌 What You Need to Know
According to automotive specialists, sidewall bulges typically form when the internal layers of a tyre are weakened or otherwise compromised.
In most cases, this damage occurs after a vehicle hits a pothole, curb, or drives for long stretches on underinflated tyres.
A hard enough impact can separate the internal rubberised cords, known as plies, allowing trapped air to push outward and form a visible bump.
Driving on tyres with low air pressure also causes excessive flexing, which gradually weakens the sidewall and tread over time, experts explain.
Although rare, some sidewall bulges have been traced to manufacturing defects rather than to everyday wear and tear from the road.
Tyre experts warn that sidewall bulges should never be ignored, since they can eventually lead to complete tyre failure while a car is in motion.
