Is Patching a Run-Flat Tire the Same as Patching a Regular Tire?
1 Answers
Patching a run-flat tire is not the same as patching a regular tire. Self-sealing tires: Regular tires have sealant attached to the inner side. Simply remove the puncturing object, inflate the tire fully, and the sealant will fill the puncture from the inside out without needing disassembly, achieving self-repair. The drawback is that it may not self-seal larger punctures or leaks, and if self-sealing fails, the presence of liquid inside the tire prevents conventional patching methods, requiring a new tire instead. Run-flat tires: These are regular tires with ultra-thick sidewalls. In case of a leak, the sidewalls do not collapse and maintain their shape, allowing short-distance driving to a tire shop for conventional repairs. The downside is that the tires are too stiff, resulting in poor ride comfort.
