I purchased 4 Michelin tires on 11/14/08 for $$1528.15 Waaranty for 60 months. After just 7, 000 miles the defected front tires were worn. Discussed the issue with store manager to no avail, will not honor the warranty, had to purchase 2 front tires at $658.15. I will no longer buy products from Costo because of their dishonesty and mediocre customer service. Invoice # 004450150289 & Invoice # 004450157005 read full review »
