I only buy tires locally now. Used to save a little money by buying online but just really prefer the long term support that a good shop has to offer. A flat repair costs about $40, but if the tires are from my local shop, it's free. Also get discounts on alignments, etc. I'd say befriend someone that runs a quality wheel/tire store. Also I've been told that Costco has good prices and service on tires but I've never used them for that.
