There are no Costco only tires made. I order specific tires there usually, such as BFG all terrains. I only buy tires at Costco for the daily drivers. Their price is very competitive, especially if you consider their free road hazard warranty. They are very generous giving warranty claims, be it road hazard or mileage warranty for wear. The other great thing is that my wife shops there and can get tires while she re-stocks our fridge. It is hands off for me.
