Lately I've been going to Kal Tire and having good luck.
When I want recommendations, I've been sending emails or facebook messages to all my friends and co-worker. People really do want to help one another! (Unless you are a greedy CT Owner, LOL!)
Lots of recommendations for alternatives to Crappy Tire, here too:

Pretty hilarious!
Kal Tire comes up there, too. Or Costco or even Walmart. I like to support small local shops, though.
