Considering you're in Canada, I'm guessing some all-terrain and/or winter tires are in the works?
I've personally used the Yokohama Geolandar A/T-S in tire size 215/60R17, which are VERY close to stock tire size, and they do great off-road. They are also supposedly good in winter conditions, though probably cannot match a true dedicated winter tire. However, the Yokohama Geolandar A/T-S all-terrain tires are not optimal for dry pavement use as I have found.
With heavy dry-pavement use, some rain, a bit of mud and dirt, my A/T-S tires only lasted 35,000 miles (though I drive VERY hard and spiritedly), and I found it to sacrifice a moderate amount of dry pavement grip, which made me feel a little uneasy in dry conditions, especially during emergency maneuvers and panic-stop braking. As a result, I went back to the stock Yokohama Geolandar G95 tires in P225/55R17.
