Can a slightly bulged tire still be used?
2 Answers
Tire bulges, even if very small, are not recommended for continued use. Firstly, tire bulges mostly occur on the sidewall (tire wall) because they are caused by localized breakage of the sidewall's cord layers. The sidewall is the most vulnerable part of a tire. Once a tire bulges, it not only affects driving but also significantly increases the risk of a blowout. Most importantly, it poses a major safety hazard. Below is relevant information about tire safety: 1. If you are considering replacing the tire, you can have it inspected at a 4S shop or a professional auto repair shop. If the damage is indeed minor, it can be repaired and continue to be used. However, if the damage is severe, the tire must be replaced immediately. 2. Tire repairs can be understood as "locking the stable door after the horse has bolted." The strength and quality of the tire can never be restored to their original levels. Therefore, instead of spending money on repairs, it is better to invest a bit more and replace the tire directly. 3. If you decide to replace the tire, the two tires on the same axle must be of the same brand, model, tread pattern, load index, and speed rating. There are many causes of tire bulges, such as incorrect tire pressure, poor road conditions, accidental impacts, aggressive driving, etc.
A few days ago I experienced this firsthand - noticed a small bulge on the tire sidewall but thought it was nothing serious. Then while driving on the highway, BANG! The tire suddenly burst, nearly causing me to lose control and veer off the road. Terrifying! Later I learned that tire bulges indicate broken internal steel belts or cords - like an internal wound. Even tiny ones can rupture dangerously at high speeds or on rough roads. No matter how small the bubble looks, you must replace the tire immediately. Now I've made it a habit to inspect all tires (including sidewalls for cuts or bulges) every time I park, plus regular maintenance for peace of mind. Safety first - never risk your life to save a few hundred bucks on tires.
