Because of storage limitations, DMC does not stock tires.  We recommend that you shop Discount Tire, Sams Club, Costco, and Tire Rack.  Tire Rack is an online supplier that many of our customers go to for tires.  The tires are shipped to us and when the tires arrive we will schedule an appointment to install them.  If we do the tire installation we cannot offer any road hazard or life time rotation.  We do not recommend rotating tires without balancing as this can lead to a vibration if the rear tires were out of balance before rotation.  If we find foreign objects in your tires while it is in for service, we can repair them.  www.tirerack.com
