USE RETREADS. Premium tire makers design casings for retread use. Theoretically, undamaged casings can be repeatedly retreaded, although the tire maker’s casing warranty might run out at, for example, 750,000 miles or after three retreadings. On the downside, some carriers restrict retread use on steer axles, and some states limit the number of times a steer tire can be retreaded. If the retread isn’t from a reputable dealer, or if its markings have been scrubbed off the side, think twice before buying.
