tires23 has the best prices locally since your from the west end.
i would say they are probably one of the cheapest places to get tires in the GTA.
i called Wheels Direct and their prices are still higher than tires23, and wheels direct is located in markham.
note: tires23 carries the most variety in tire selection than anyone i know (that have reasonable pricing). wheels direct carries the main brands. they can’t get the import brands like falken and federal (i know since i just called them asking for falken 512s for my parent’s car).
