Crappy Tire is know as a slang word to indentify the Canadian retail distributor "Canadian Tire" They call it Crappy tire because of the low quality of their in-house brand "mastercraft" being that most of the product is made in China not to mention that the Mastercraft line is overpriced versus a retailer such as Walmart.
It also refers to the "crappy" service because there's never enough people in the stores working cashier or customer service.
