It's really interesting that these two methods for retreading coexist. I imagine the first method is cheaper but the seam in the tread would yield a less durable type, or perhaps lower speed rated, but it cooks dozens of tyres at a time in the oven, compared to the mould-cured method's one at a time. I think the video still would have been fascinating if you'd included all the rubber mixing stages. Heavy machinery chewing on rubber like a cow on grass. I worked at a small retreading company for about 6 years retreading truck tires. They also retreaded car tires, but stopped in the late 90s due to less demand. Truck tires, on the other hand, are always in demand. It was tiring and heavy work and very hot. One guy scraped the tread and I did all the rest of the work for the finished product. We managed about 8-12 tires a day, depending on the sizes. I left there in 2002. Now they have 8-10 employees and manage 32-40 tires a day. This is the sort of video that is the reason I do not bother with a TV licence. 20 Minutes watching a well produced video and I have learned something new. thumbs up mate, keep making quality videos like this.
