Canadian Tire has a sale this week on the Hankooks and General Tires. If you plan on getting separate rims, it could cost you about $700-800.
If you are looking to save some money, search kijiji for your local area. There are always people that have a set of tires that were used for just one season, sold the vehicle, and want to get rid of the tires.
Also, when searching on kijiji, search for both the OE tire size (235/65/16) and 225/70/16.
