I put the Forteras on my wifes MDX. Let me say that they are a great highway tire. They are very grippy in the rain, very grippy in the dry, and make the car into a decent light offroading SUV, which the MDX certainly is not. I took the MDX to a moderately muddy fishing area that I go to, and even with all the rain we got, the truck never even came close to getting stuck. Even my 4runner got stuck in this area with the Dunlops (had to lock the center diff and rock the truck for several minutes to get out). The MDX went right through with these tires.
I just got first generation Revos for my 4runner. I am not sure how I feel about them. The good is they look amazing on the truck and very rugged. A very pretty girl that I know saw them and said they make the truck look "tough and manly". I might keep them just for that! But they are an A/T tire, and therefore, are noisier than a highway tire. May not seem like a big deal but on long trips it can get a bit annoying. The Firestone Destination A/T's are really rugged and squared off looking, but I also don't like the lettering style. They have been getting rave reviews on Tire Rack though.
Overall, I would very seriously think about what kind of driving you do, and be honest with yourself: if you really only offroad .005% of the time, and the rest is high speed interstates, there are highway tires that look decent and will work better.
One final word: don't go with the highest treadwear rating. The 4runner, in both 4.0 V6 and V8 engines, is a powerful truck. You are putting a minimum of 265 ft/lbs of torque to those back wheels in 2wd. That is more than some Camaros and Mustangs had back in 80's and 90's, and its on a truck tire, not a low profile street tire. A high treadwear, hard rubber tire will set off the VSC on a 4 runner anytime you gun it more than 1/2 throttle. A buddy of mine with an Xterra stupidly got 720 treadwear Michelins and he is kicking himself right now, because there is no grip from under hard acceleration. No forward thrust means his VSC is always kicking in- its actually dangerous and not very much fun. Just my two cents!
