in November 2017 we purchased a set of Michelin Tires from the Costco Tire Center in Burnsville, Minnesota for our 2014 Hyundai Elantra. The Tires we purchased supposedly had a 60,000 mile warranty on them. When we recently took the car in for a regular oil change, the mechanic told us the tires on the back of the car were almost totally worn out. We only had 24,000 miles on those tires. He called me into the garage where he had the car on the rack and I saw that the outside of each tire was completely bald, while the inner side of the tire had some tread, but not much. The front tires were in better shape, but at least 3/4 of the tread was gone on them too. I took the car in to the Costco Tire Center, expecting them to provide me some discount on a set of new tires, based on the premature wear of the tires. I expected some type of pro-rata discount. He said that the wear was funny and that it must be some type of mechanical problem. He also said that the tires hadn't been rotated twice, as they should have been, and they weren't going to warranty the tires in way. I admitted that we probably hadn't rotated the tires, but there is no way they should have worn that way in just 24,000 miles. Long story short, I had to buy a new set of tires after just 24,000 miles. Just beware that when you buy tires with these supposedly high mileage warranties, and you do have a problem with the tread wearing out much earlier, the Tire Center at the Store will look for any way to void that warranty. I am convinced that even if I had rotated the tires, they would have simply said it was some type of mechanical problem. I had truly come to expect more from Costco.
