I sure can. A company buys a brand new tire. It can be an entry-level, a medium or a premium tire, but it's a tire with a good casing that is built with typical standards. They run that tire until the end of its tread life, and then they send it to us. We bring it in. There's a very complicated process to inspect it to make sure that there's no damage to what is called the casing. Then we put it into a buffer, and this machine buffs off all the old tread. You put some gum rubber around it, and you stick a new tread on it. You seal it, and you bake it for a couple of hours to make it into a new tire. Then it comes back and goes through another inspection process.
You can theoretically do that into perpetuity, but we generally retread three times on average. You can retread it up to five times. Some companies do it an unlimited number of times, but it all depends on the quality of the casing and whether there's been any damage to it during its life.
