I’ve changed the tires on a split rim truck a few times, and I’ve seen tons of scary videos of them being installed as well, but I’ve never seen anything like this. They are usually referred to as split rims, but in truth they are more of a split ring. That split ring makes up the bead on one side of the tire and fits under a lip on the rim shell itself. Because they are metal on metal they sometimes rust between the ring and rim which can make them hard to remove. And if the ring isn’t seated correctly and the tire is inflated then that ring can become a deadly projectile. Whether you are taking the ring off, putting the ring on, or inflating the tire, this sucker can really hurt or even kill you.
What’s funny is that the Pakistani Truck guys just change these things out like it’s nothing and with a speed and confidence like I’ve never seen before, even in shops that work on old school trucks all the time. They also have some pretty creative tools, like the impact support cart. These 1 inch impacts are beasts and their little cart sure makes it easier.
