What are the causes of tire bulges?

[BeckettFitz]

Tire bulges can be caused by the following reasons: 1. Tire bulges occur due to excessive internal pressure. 2. During driving, if the sidewall of the tire is impacted, it can cause the sidewall fabric to rupture, allowing external air to enter the tire and form a bulge. Tires cannot be repaired under the following circumstances: 1. Damage to the tire sidewall cannot be repaired. 2. Holes in the tire crown with a diameter exceeding 6 millimeters cannot be repaired. 3. If there is damage or deformation to the bead, tread deformation, rubber corroded by chemicals, or damage caused by driving under-inflated, the tire cannot be repaired. 4. If the tire has a bulge.

I've encountered tire bulges several times, mainly caused by impacts to the tire sidewalls from hard objects. For example, accidentally driving over large potholes or scraping against roadside stones can break the internal cord layers, leading to bulging. Insufficient tire pressure is another common factor - when pressure is too low, excessive tire deformation during cornering or bumpy roads makes internal damage more likely. Additionally, aged tires are prone to this as hardened rubber loses elasticity, making them vulnerable to frequent high-speed stress. Last time I spotted a bulge on the highway, I immediately slowed down and changed to the spare. Remember to check tire pressure at least monthly and avoid aggressive driving on poor road surfaces.

The most concerning aspect of tire bulging is the significant safety hazard it poses. Once a tire bulges, it becomes prone to blowouts, especially at high speeds, potentially leading to loss of control. Common causes include insufficient or uneven tire pressure, which puts excessive stress on the tire sidewalls, causing them to deform and bulge. I always make sure to avoid potholes while driving and park carefully to prevent scraping against curbs, as impacts with these hard objects are the primary culprits. Aging tires or manufacturing defects, such as worn cords or damaged inner liners, are also common. If you notice a bulge, address it immediately—don't delay. Before replacing the tire, check the pressure frequently and perform regular maintenance to extend tire life.

Tire bulges usually indicate internal structural damage, such as broken cord layers, where air seeps in and forms a protrusion. I often help friends inspect their cars and find the most common causes are hitting hard objects while driving or low tire pressure leading to deformation. Aging rubber from prolonged use or manufacturing defects can also cause this. Develop a habit of walking around your car before each drive to check for any abnormal bulges, maintain tire pressure at recommended levels, and replace tires before they exceed three years of use.
