Greetings:
look into places, often in poor neighborhoods, that install and sell used tires. since they have low overhead, and don't sell new tires anyway, they aren't as hostile. also, many mail orfer places, like tire rack, have lists of local installers for their tires. these folks may install yours. lots of places have tire mounting and balancing machines, not all of them are regular new tire dealers. also, ask the guy off craigs list where to go. the local CL has 3? people always selling used tires, they must have some connection.
