Retread

Last reviewed: 2026-05-20

A tire produced by inspecting a used casing, buffing its surface to a precise profile, optionally repairing damage that meets retreader standards, and bonding new tread rubber through a controlled vulcanization process. There are two main methods: pre-cure, where a pre-molded tread band is applied and vulcanized, and mold cure, where uncured tread rubber is shaped in a heated mold around the casing. Quality depends on the casing's condition and history, the retreader's inspection standards, the tread compound quality, and the precision of the curing process. A quality retread on a suitable casing, in an appropriate position, can deliver comparable performance to a new tire in many drive and trailer applications.

Retread suitability depends on much more than a visual inspection by the driver or dispatcher. The retreader uses both visual and non-destructive testing to assess the casing for structural integrity before accepting it. Position policy at the fleet level further restricts where retreads can be used — steer axle restrictions are common even when the tire and casing would pass retreader acceptance. Pressure and load management after retreading matter as much as before: a retread run severely underinflated loses its casing bond and may fail through tread separation regardless of the initial retreading quality.

Real-World Use

A small regional fleet implements a retread program on drive positions, selecting a retreader with a documented quality process and establishing a casing tracking system by DOT TIN. Drive tire cost per mile decreases in the first year. Trailer positions are added in year two after monitoring drive performance. The steer axle new-tire policy is maintained throughout because several fleet customers contractually prohibit retreads at steer positions — a position restriction that applies regardless of retread quality.
