Walmart.com has a list of all the Walmart locations in the country and notes which locations offer auto services. There are over 2,500 Walmart locations that have Auto Care Centers in the United States, but not all Walmart locations contain an Auto Care Center.
The store finder feature on Walmart.com operates based on ZIP code or a combination of city and state. Upon entering one of these pieces of information, a list of all nearby Wal-Mart locations displays. Clicking on each location in this list provides more information. The list of services each Wal-Mart location offers is available in this information window, including whether or not the location provides tire and other car services.
