I've read great things about Ace Moto at GTAM.
I'm guessing since you did other things done, you took your bike? How much was the tire change if you bring the bike in?
As I was in no rush, I left my bike with him and picked it up the following day. $55 per tire if on the bike and $35 off... no disposal fee's and no other costs. He'll do all the work right there in front of you while you wait, stand-up guy with a lot of knowledge.
