I'd stay away from any of the MTRs since they are overkill for most things, especially in a stock rig. Here are my suggestions based on lots of experience:
- Nitto TerraGrappler - These are some of my favorite tires. Even in the P load range, they'll hold up well over rocks. I did a lot of off roading in Pennsylvania with TGs and they never let me down. They also do well on the road and rain. The plus is you can get them in a 265/70/16
- Bridgestone Revo 2 - Slightly more expensive than the Nitto, these are some of the best all around tires that money can buy. I used them for several off road trips and they handled everything I could handle at them. They offer slightly better on-road handling than the Nittos and liked the snow better, but I'm not sure I'd say they were significantly better.
- Kumho Road Venture SAT KL61 - These are relatively new tires and served me well on my 2005 Tacoma. They handle snow better than anything I have ever used (close to a dedicated snow tire) and pull over rocks and mud without a problem. I'd say they are less aggressive than the other tires listed here, but for a stock rig, they are pretty good.
265/70/16 is a good tire size and while you may not rub under normal conditions on a stock 4Runner with 265/75/16, you will rub when you are off roading. You gain a 1/2 inch of height with the 75 series which can be helpful, but for the most part, you won't notice it. They will decrease mileage by 2-4 mpg over highway tires at 265/70/16 as well.
