In North America right now, it only applies to commercial tires. When we were all younger people, retreaded tires on passenger vehicles made more sense and were economically viable. Since the late 1990s or early 2000s, very little passenger tire retreading has gone on, because there's not enough material in the product to make it make sense to put the labour on top of it to retread it, whereas a truck tire has an enormous amount of steel, a lot of rubber, a lot of technology, frankly, and the bead that goes in that tire. That's why they cost so much money, because there's a lot that goes into it, and it makes sense to retread.
