Often times it can be difficult to schedule tire appointments for travelling RVers. Discount Tire is a great resource because you can order your tires ahead of time and get them shipped to you so you know the tires you want are in stock and they will install them for you or you can bring them to another tire shop to get them installed.
However because you bought them through Discount Tire they will honor the warranty nationally. You also can support the local tire shop by hiring them to install the tires. Everyone WINS!
