How to Repair a Slightly Bulging Tire?

[Troy]

If the bulge is relatively small, some repair shops may use a hot patch method for repair. Hot patching, also known as vulcanization, fundamentally addresses the issue of broken cord threads. Hot patching requires a higher level of technical skill from the technician, and it is generally recommended to directly replace the tire with a new one rather than attempting a repair.

A slightly bulging tire can't be repaired at all—it must be replaced, and this is something you absolutely can't take lightly. Just last week, my buddy's car had the same issue. He thought he could still drive on it, but after just 200 kilometers on the highway, the tire blew out. Actually, a bulge means the tire's inner ply cords have broken, making the sidewall dangerously thin, like a balloon swelling up. If you press it, it feels soft—this kind of structural damage is impossible to fix, and even plugging it with a tire rope won’t help. Every repair shop will advise you to replace the tire immediately because it could burst at any moment while driving. If you notice a bulge, don’t exceed 80 km/h, and head straight to a reputable shop to get a new tire of the same specifications. Oh, and when replacing the tire, remember to check if the rim is deformed—that could also cause bulging.
