What's wrong?
The tires on the 2018-2021 Chevrolet vehicles covered by recall 21V115 are the only parts that touch the road. Each tire supports the vehicle and keeps the tread in contact with the pavement while you steer and brake. The tire has to hold its shape under load, heat, and speed.
These tires were cured for too long during production. Curing is the heat and pressure step that sets the rubber into its final shape. Because the process ran beyond Continental's specifications, the affected tires do not match the intended production standard. Chevrolet identified suspect tires by DOT number and production mold number combinations, then matched those tire records to vehicle build records.
There is no warning sign before failure. A tire affected by this recall does not give the owner a reliable early symptom tied to the overcure condition, so the VIN and tire identification details decide whether the vehicle is included.
Who's affected?
The listed scope crosses several body styles, including crossovers, SUVs, vans, and pickups, and each included vehicle is tied to the tire component.

What's the safety risk?
Over cured tires can develop a sidewall break, sudden air loss, belt edge separation, or tread and belt loss. Any of those failures can cause loss of vehicle control and increase crash risk. If your VIN is included, schedule the tire inspection promptly and avoid driving on damaged or abnormal tires. Repair will be free at any franchised Chevrolet dealer once available.
What should I do?
- Check your VIN to confirm your 2018-2021 Chevrolet Traverse, Blazer, Tahoe, Acadia, Yukon, Savana, Express, Sierra 1500, Yukon Xl, Silverado 1500, Suburban, Escalade Esv, XT5, Escalade, Enclave, or XT4 is included in this tire recall.
- Watch for the owner notice if you have not received one, then contact a franchised Chevrolet dealer for the free tire inspection.
- Schedule the tire inspection and replacement that addresses over-cured tires, sidewall breaks, sudden air loss, and tread or belt loss.
- Bring the recall notice if you have it. If not, reference recall number 21V115 when you call.
- Drive cautiously until the tires are inspected. Leave extra following distance and stop driving if a tire loses air or shows sidewall damage.
What happens at the repair
Chevrolet's final dealer repair is not listed as available, so do not assume a dealer can complete it today. Once it opens, a Chevrolet technician will inspect the tires and replace any tire with the DOT number and production mold number combinations identified by Continental. Parts and labor will be covered under the recall. If you already paid to replace an affected tire, the owner notice gives instructions for applying directly to CTA for reimbursement.
