Commercial Tire Retreading: Costs, Positions and When It Pays

A new commercial tire is priced for both of its parts: the casing, which is the expensive engineered structure, and the tread, which wears away. A retread reuses the casing and replaces only the tread. The fleet pays the retread price instead of the new tire price for each additional tread life the casing delivers.

That is why the comparison that matters is cost per mile, not tire price. A cheaper tire that gives fewer miles and a casing that cannot be retreaded can cost more per mile than a premium tire whose casing carries two more treads. Purcell does not quote a fixed saving here, because the figure depends entirely on the fleet: the casings it buys, how it runs them, and how many come back from inspection.

What a fleet can do is measure it. Record the purchase cost and miles for each tire life, new and retreaded, and the cost per mile appears. Tire tracking and fleet reporting covers how to set that up.

Fleets that run retreads commonly decide by position. The pattern below reflects common industry practice, and each fleet should set its own policy with its store.

Trailer axles. The most common place for retreads. Trailer tires roll rather than steer or drive, and trailer positions are where many fleets start.

Drive axles. Widely retreaded in commercial fleets. Drive tires take torque and wear differently from trailer tires, so the tread design chosen for a drive retread matters.

Steer axles. Many fleets keep new tires on the steer axle as a matter of policy, and some regulations restrict retreads on the front of certain vehicles. Check the rules that apply to your vehicle class and your own policy before deciding.

Mixed and vocational units. Refuse trucks, dump trucks and other vocational vehicles often run retreads on drive positions, where stop-start work and site conditions wear tread quickly and casings stay sound.

Retreading is not automatically the right call. It tends not to pay when:

• Casings rarely pass inspection because tires are run flat, run low or run to the belts.
• The fleet buys casings that are not built to be retreaded.
• Units are sold or retired before tires reach a second life, and nobody plans for the casings.
• Nobody tracks results, so the fleet cannot tell whether retreads are delivering.

Each of these is fixable, but each needs fixing before a retread program can show its value. The guide to extending casing life covers the habits that keep casings sound.

A retread program starts when new tires are bought, not when they come off. A casing built for multiple lives, sized consistently across the fleet and run within its rating gives the program something to work with. A fleet that buys on new-tire price alone often ends up with casings that do not return.

Standardizing sizes across the fleet helps too. Fewer sizes means casings can move between units, and a retreaded tire can go on whichever unit needs it rather than waiting for a match.

Casings are collected at the Purcell location the fleet already uses. Purcell collects at 54 locations and retreads at seven plants, and the casings come back ready to run. A fleet deals with its store rather than the plant. The national retreading page lists every collecting location by state.

Fleets running a program through fleet services usually fold retreading into it: specifications by position, pull points agreed in advance, and records that show what each casing delivered. The commercial fleet page covers how Purcell works with trucking operations more broadly.

If your casings are sound, your tires are pulled before they wear through, and you can measure cost per mile, retreading trailer and drive positions is usually worth a trial. Start with one position across part of the fleet, track it for a full tread life, and compare it with new tires on the same routes.

If your casings are not coming back from inspection, fix that first. Retreading a fleet that destroys its casings is buying tread for structures that will not last.
