I am a hard core fan of Costco and this time I am rating their Tire Service Center. I HIGHLY recommend using them for your tire and or battery needs. I had initially purchased all replacement tires from Costco some time ago. The tires come with a warranty, nitrogen without an extra cost, every six thousand miles they will balance and rotate your tires for free. Apparently they also fix a tire for FREE if it is repairable. Unfortunately, my tire was not repairable and was prorated a brand new tire where it was covered %60 and I ONLY paid less $53.33 for a new (name brand) replacement tire and same make/model, etc to match my other tires. I was very happy with this since it would have cost me who knows how much elsewhere that doesn't offer anything that Costco offers. I was very pleased with Representative Corey who was cheerful and very helpful during this situation. I had my car towed in and the wait time was quick and efficient. Also, if you get tires from Costco you can also fill get your tires checked with them placing air in them without any charge at any of their locations. I will NEVER purchase my tires or battery elsewhere. 100% satisfied customer ALWAYS.
