You purchased an opening price point radial. The tires you requested are no longer available, but if you wanted the Goodyear Integrity the Sailun will work about the same. Sailun tires are sold as the entry level for their price. If you wanted a premium product you should have asked for it by name. Shopping price gets you Sailun or Gaja tires. Keep in mind though tire units like those have passed all of the DOT requirements and are safe radials for passenger vehicles. Next time you shop I would suggest something in either the Michelin MX series or in the Bridgestone Turanza line. These units boast 80K+ tread wear warranties and also come with 5 year-6 year maufacturing warranties.
