Tires with slight bulges should not be used. The specific reasons are as follows: 1. A tire bulge occurs when the internal cords in the tire's ply layer break, causing the gas to push outward from the broken cords. Without the support of the cords, the elastic rubber will bulge under the pressure of the gas. 2. When a tire bulges, it indicates that the internal cords have already broken, and continued use may lead to a tire blowout. Additional information: To extend the lifespan of the tires, it is essential to avoid bulges by regularly checking the tire pressure and ensuring it remains within the normal range—neither too high nor too low. When driving, slow down when encountering harsh road conditions, and park the vehicle on a flat surface whenever possible.

To be honest, you really can't take tire bulges lightly. Last week, my neighbor kept driving with what seemed like a small bulge, and it ended up blowing out on the highway—scary stuff. A tire bulge means the inner cord layers are broken, just like an aneurysm that could burst anytime. Sidewall bulges are especially dangerous since there's only rubber holding it together. Regular repairs are useless; mechanics say you've got to replace the whole tire. Slow down over speed bumps and maintain proper tire pressure to reduce the risk of bulges. If you spot a bulge, head straight to a repair shop—don't gamble your life to save a few hundred bucks.

A tire bulge essentially indicates internal structural damage. When the layers of cords in a radial tire break, air pressure pushes the rubber outward, forming a bulge. At high speeds, the tire rotates thousands of times per minute, subjecting the bulged area to several times more impact force than normal. The most alarming case I've seen was a bulge hidden on the inner side of the rim, unnoticed by the owner until a routine check. Always perform wheel balancing when replacing tires, and never compromise safety by opting for cheap used tires—safety is non-negotiable.

Driving with a bulging tire is like carrying a time bomb. When the steel belts beneath the rubber layer break, the tire is more prone to blowouts in hot weather. Especially dangerous are bulges on front tires, where the risk doubles as a sudden blowout can cause loss of control. A repair shop mechanic taught a self-check method: while washing your car monthly, feel the tire sidewalls for any abnormal protrusions and get them inspected immediately. When replacing tires, it's recommended to change both tires on the same axle to avoid uneven grip. Also, check if the wheel rim is deformed, as an out-of-round rim can lead to abnormal wear.

Once a friend asked me if a bulging tire could be repaired, and I just pointed to the dissected sample hanging on the tire shop wall. The broken cords were as tangled as a mess of hemp—tire sealant couldn't even penetrate. A bulge is like the thin spot on a balloon about to pop; hitting a pothole might make it burst. Nowadays, a new tire only costs three to five hundred, and a blowout could cost more in repairs. Important reminder: If you notice a bulge, drive slowly to the repair shop. If on the highway, pull over to the emergency lane and switch to the spare. Never use a patched old tire as a spare—it's a matter of life and death.

Never! Never use bulging tires again! Last year during rainy weather, I witnessed a high-speed tire blowout caused by a bulging tire firsthand—the car spun three times on the road before crashing into the guardrail. Even now, the memory sends chills down my spine: when the rubber layers separate, the tire's strength drops to less than 30%, making it even more dangerous in hot weather. Detection is simple—just shine a flashlight on the tire sidewall; uneven shadows indicate bulging. For emergency handling, deflate the tire before moving the car, but it's best to call a tow truck. For prevention, pay attention: avoid scraping curbs, check the production date when replacing tires, and beware of aging cracks on tires older than five years.
