I'd have to aggree with Dave. I tried dealing with the Carling tire guy, and he came off as a bit of an A-hole. Talked to them on the phone, and he told me to come in to get the tires installed, and when I actually went in, he said "sorry, I stopped taking people at noon. Try again another day." I was pretty pissed. Endded up going to Crappy tire...they were expensive though. So I would say give Costco a try.
