I would have thought that with the popularity of supercrews in 4x4 that 18 inch tires would be widely available here in Alberta. Well after phoning a lot of places I decided to go with the Fountain Tire deal of buy3 and get one free. So for a grand installed, its the best deal I could find. Only problem is the tires are special order and take 5 weeks to ship. Sure seems odd that they aren't more readily available.
