Can the tire bulge still be opened

The tire bulge cannot continue to be driven because if the tire bulge is light, it will affect driving stability, and it is more likely to lose control under extreme driving conditions. If it is heavy, it can easily cause a tire blowout on bumpy roads, high temperatures, sudden braking, or high air pressure.


But in some repair shops, some may claim that smaller protrusions can be repaired through thermal repair, which involves the raw rubber being melted onto the tire wound through high-temperature vulcanization and cooled to solidify to seal the wound. In fact, this method did not fundamentally solve the problem, but instead thickened the rubber at the protrusion, which does not deny that it has played a certain role. However, long-term or high-speed use carries significant safety risks.

Moreover, hot repair requires high technical requirements from the master. If the high-temperature curing time is too long, it can lead to sulfur exceeding standards, tread embrittlement, cracking, and surface blueing. If the time is too short, it will cause sulfur deficiency and the repaired area will easily fall off. To prevent omissions or technical defects during the repair process, it is recommended not to open the tire drum and replace it immediately.

The tire bulge is caused by a broken cord. The side of the tire is the thinnest part of the entire tire, and there is no steel wire inside. There are only nylon wires supporting it to prevent the gas from bulging out. This is the main function of the tire fabric layer, which is the skeleton of the entire tire. When several wires are broken at the same time, only rubber is left to support this area, resulting in very poor strength and quickly bulging.

If the bulge is relatively small, it can be repaired by hot patching. Hot patching, also known as hot patching, involves using high-temperature vulcanization to blend raw rubber onto the tire wound and cool it to solidify, thereby sealing the wound. Compared to internal patches, hot patches can be more suitable for various types of tire scars, and even bulges and sidewall repairs can be repaired. However, the technical requirements for hot patching are relatively high for the master, as if the high-temperature vulcanization time is too long, excessive sulfur will be generated, leading to serious embrittlement of the tread, easy cracking, surface blueness, and other phenomena of pattern grooves. If the time is too short, it will cause sulfur deficiency, and the repaired parts are prone to detachment.
