Thanks for the response, but if I walk in, buy a tire and walk out with it, all those things you list are moot and unnecessary; same as when I buy 6 quarts of oil and a filter. Do dealers jack up those costs when I don't have them do my oil change? Don't think so . . . as I have found dealer oil and filter prices only slightly higher and do not mind that. Dealer tire prices are way, way more.
I thought parts, service and sales are separate departments. Why would costs for the service department (shop,equipment,tools,electric and insurance) be passed over to a different department?
Oh well, it is what it is - I just think tire prices should be at least within $20 of what is charged on the www and I don't mind paying a little more for the install when bringing in my own tires.
