How to Check for a Michelin Tire Dry Rot Recall

Identify the possible campaign

Dry rot is the common name for cracking in the rubber of the sidewall, in the tread grooves or around the bead area. It usually develops as the compound loses flexibility. Common causes are age, sunlight, ozone, heat, long periods of parking, chronic underinflation and harsh cleaning or dressing products. A safety recall is something different. It is a manufacturer's formal campaign covering a defined group of tires, identified by tire line, size, production plant and a range of production dates. A report about one Michelin line therefore does not mean every Michelin tire, model year or vehicle trim is involved. Treat online complaints and news stories as a reason to check, not as proof that your set is included.

Before searching, look closely at the tires. Fine, shallow surface lines, often called weather checking, can appear on tires that are otherwise sound. Cracks are more serious, whatever the recall status, if they are deep, widening, running around the tire or showing anything beneath the rubber surface. Note where the cracking is, how many tires show it and whether the spare is affected. The inspecting shop will want to know that pattern.

Confirm the exact vehicle

Recall applicability depends on identity at two levels. The first is the vehicle identification number, found on the dashboard near the windshield, on the driver door jamb and in registration documents. It links your car to campaigns issued by the vehicle manufacturer. Those campaigns can include original equipment tires when the automaker takes responsibility for them. They are limited to specific model years, plants and build dates rather than an entire nameplate. If the tires have been replaced since the vehicle was built, the vehicle number tells you nothing about the tires now on the wheels.

The second level is the tire itself. Tire recalls are tracked by the DOT tire identification number molded into the sidewall. It begins with the letters DOT, followed by a plant code, a size code, an optional manufacturer's code and a four-digit date code. The date code shows the week and year of production; 3419, for example, means the 34th week of 2019. The complete number may appear on only one side, so check the inboard sidewall too. Write down the full number for every tire, including the spare. Also record the tire line name, tire size, load index and speed rating. Compare the size and ratings with the vehicle placard on the driver door jamb to confirm the tires are a correct fit.

Verify coverage and status

Check current official records rather than relying on a saved list or a forum post. The National Highway Traffic Safety Administration keeps a public recall database. You can search it by vehicle identification number for vehicle campaigns and by tire brand and line for tire campaigns. Compare any listed tire recall against your full identification numbers and production dates. Michelin customer care and authorized Michelin dealers can also check a specific tire identification number against the company's campaign records.

If a campaign appears, note its recall number, the affected range of identification numbers and its status. Some records show a remedy available now, while others show that replacement tires are not yet ready. Records change as campaigns are opened, expanded or closed, so a clean result today does not rule out a future notice. Register your tires with the manufacturer, either through the seller at purchase or later using the identification numbers. Registration is the main way a tire maker can contact you directly if your set is added to a recall.

Understand the remedy

A safety recall applies when a manufacturer or the federal regulator finds a defect that creates a safety risk, or finds that the product fails a federal safety standard. The owner notification letter describes the remedy, which is usually inspection and replacement of affected tires. The letter also states any conditions and deadlines. Read it promptly and follow its terms, and do not expect a recall to cover tires outside the listed identification range.

Technical service bulletins are not recalls. Vehicle manufacturers issue them to tell technicians how to diagnose or repair a known condition, and they do not by themselves promise free repair. Warranty coverage is a third path. Michelin's limited warranty covers defects in workmanship and materials, under the terms, time limits and any tread-wear proration printed in the warranty booklet for your tire line. Whether cracking qualifies depends on those terms and on an inspection. The inspection has to separate a manufacturing problem from aging, damage, incorrect inflation or care products. Any goodwill adjustment beyond the warranty is at the company's or dealer's discretion, so get the decision in writing.

Arrange the next step

Gather documentation before the appointment. Bring clear photos of the cracking on each affected tire, the full identification numbers, the purchase invoice, the installation date and mileage, and any rotation, alignment or inflation records. Take the vehicle to an authorized Michelin dealer. If a vehicle campaign covers the original tires, go to the vehicle dealer instead. Ask for the inspection result and campaign number in writing. After the work, keep the invoice listing the new tires and their identification numbers. Then confirm in the official records or with the dealer that the recall shows as completed for your tires or vehicle.

Until the tires are inspected, check them often. Stop driving and fit a serviceable spare or arrange towing if you see any of these: cracks deep enough to expose cords or belts, a bulge, separation, chunks missing from the tread or sudden vibration. Keep inflation pressure at the value on the vehicle placard, measured cold, not the maximum molded on the sidewall. Check tread depth across the full width of the tread. If cracking is significant, avoid loading the vehicle near its limit and keep highway speeds moderate.

If tires must be replaced, under a recall or otherwise, match the tire size listed on the vehicle placard or in the owner's manual. Use a load index and speed rating no lower than specified. On all-wheel-drive and some four-wheel-drive vehicles, drivetrain compatibility also matters. The owner's manual may limit how much tread depth or rolling circumference can differ between tires. That can mean replacing tires in pairs or as a full set, or having a new tire shaved to match. Confirm those requirements with the installer before accepting a single replacement tire.
