These guys are awesome for both new tires and after sales service. I installed a new set of tires with them a year back and my rear tire got punctured by a screw. The guys at Canadian Tire took one look and decided I need a new tire. So I took it to Johnston — where I had bought the tires from. They took the time to explain the risks to me, removed the tire from the rim and after inspecting decided a puncture fix would do the trick. All round A-1 people and highly trustworthy.
