Depends on what kind of driving you're doing. Are you 2 or 4 wheel drive? Do you do any offroading? There's no need to go with an all terrain if all you do is highway driving. Our 4Runners aren't known for their power so adding heavier tires should only be done if you actually use the tire. Otherwise, you're just killing your pickup speed and fuel economy. I personally love the look of the Sequoia rims that I picked up. I paid around $250 for the set and got 20,000 miles off of the tires that came with them. Sold my stockers with nearly bald tires for $125 so I think I came out ahead. I've always had good luck with buying my tires off of Craigslist from actual owners...not dealers. You can usually find someone selling a near brand new set of take-off's for fairly cheap. I just picked up a fairly new set of BFG All Terrains for $200. Like I said...it's all in what you want or need.
