What kind of glue is used for repairing the sidewall of a tire?

Tire sidewall repairs use rubber. The following is an introduction about tires: 1. Introduction: A tire is a circular elastic rubber product assembled on various vehicles or machinery for rolling on the ground. 2. History: In 1845, R.W. Thomson, a civil engineer born in Scotland, invented the pneumatic tire and obtained a patent from the British government under the title "Improvement in the Wheels of Carriages and Other Vehicles." On December 10 of the same year, the first pneumatic tire was born. Tires are usually mounted on metal rims to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance. 3. Function: Tires are often used under complex and harsh conditions. During operation, they endure various deformations, loads, forces, and high and low temperatures. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows the significant amount of rubber consumed by tires.
I've done specialized research on tire sidewall repairs, and honestly, in most cases, using glue for patching isn't advisable. The sidewall is the weakest part of a tire, undergoing significant deformation under stress, and ordinary glue patches tend to crack after just a few miles of driving. For true emergency fixes, repair shops use high-temperature vulcanizing glue with specialized sidewall patches. They first clean and grind the damaged area, apply the vulcanizing glue, attach a reinforced rubber patch, and then use a heat press to fuse the adhesive with the tire's rubber molecules. But truth be told, such repairs last at most three months because once the sidewall's cord layers are damaged, it's like a strained muscle—no matter how strong the patch, it can't restore the original strength. Last time, my friend drove for two months after such a repair, and when hitting a bump at high speed, the tire bulged and blew out. It scared him so much he never skimped on tire replacement costs again.
