Please do so.....
I learned my lesson the hard way.Was on the outskirts of Grande Praririe, Alberta and blew a tire.Sunday afternoon at 3 pm.Called, guy shows up at 7pm and we got charged Sunday overtime,PLUS afterhours, PLUS their distance drive(100kms).Total to change and replace(with a USED tire)the tire? 414.00$ .
I seriously could have buried that M'FER in the bush ,but kept my cool and went into the shop in Edmonton the next morning for a chat with the good folks at(Rhymes with mountain) tire.
I made them a promise I would contact every tire dealership I could find and give them photocopies of the bill(Still have it actually).They halved the cost and that was that.Moral of the story.Get CAA.Trust me on this.
