I’m not even certain how this video popped up in my recommendations, but I sat through the whole thing and just had to share it. It really is astounding what is asked of modern technology and equipment. We expect so much life, load capacity, durability, and zero defects (an impossibility) from something like a modern tire (that spins from ~470–750 RPM at highway speeds depending upon the tire size) and don’t even really give it a second thought. Even if we are just talking about auto and pickup tires it is amazing that there aren’t more tire failures. How many men run bald tires? How many drivers never check their inflation pressure? Just to clarify, when I say “truck” tires I mean medium and heavy duty commercial trucks (Class 6-8 vehicles, with GVWR of ≥ 26,000 lbs) and not some dude-bro with a dumb smokestack his pickup bed.
Here’s another video on how to retread a truck tire. If you ever wonder why it seems like lots of trucks have blowouts, it is because truck tires are frequently regroovable and/or retreadable. The tires that are re-used in such a manner would be properly inspected if serviced by a reputable company, but it is still more likely to fail in the second life.
The more I watch some of these informational/infomercial videos the deeper the rabbit hole gets. One place I worked at for only a month had several trucks on the road that really should have been out of service. The worst one I drove actually had a different set of tires on one side of the rear axle; one side was new and the other was old and the sets had very different tread patterns. The tires were clearly not the same size and did not have the same traction. Even just differences caused by tread wear make a big difference over time.
