Costco Tire Center provides quality tires and great customer service with a friendly and helpful staff. The service includes nitrogen in the tires and a warranty with tire rotations and re-airing for the life of the tires purchased there. Work is often completed efficiently, sometimes in little over an hour or even before the estimated time, even on busy days. However, experiences can vary. Some customers report issues like incorrect tire balancing requiring a second visit, which can be frustrating. While most praise the value and service, some note that wait times can be long. Overall, many customers are very happy with the work and plan to return.
