Bruce,

Quite a few guys (and girls) that I know with trucks,jeeps and SUV's that don't want the real aggresive off-road tires but still want something that will get them through light off-road duty are the BF Goodrich Rugged Terrains.

My father has had good experience with Toyo Open Country A/Ts. They've been on a full size pickup but should be available in your size. He works in construction so they haven't been babied and the treadlife has held up very well considering the amount of on road driving he does. They don't look super aggressive but work well in sand, gravel, slush/snow in short all the lovely rally conditions.

Also Yokohama makes the Geolander A/T-S. I don't know a whole lot about them but if they can make rally tires that are durable (and support rally as a whole in Canada) they might be worth taking a look at as well.
