Lol dude, that almost happened to me at a well franchised tire store one time, and the thing is they were used tires but i still got the store to put them on w/ some "here's the cash now, or you want me to go somewhere else, lol". G/L w/ getting them on, if anything try Big 10 tires (but watch them do it so if they scratch the rims, you know they did it), or a smaller based company (maybe Tires Plus) that will put them on for you.
