A friend of mine just bought a 2013 4Runner. I ran the metric tire size though a chart and it was equal to a 32" tire. My 33's keep rubbing on the fenders, and I have no desire to cut sheet metal. The 32's will work better with the 4.56 gears I have … though I love the 33" tire with 4.56. But, I concede 32's with the 4.56 will probably work better.And yeah, Pappy I have no doubt there will be a tradeoff. Even with the V8 in the 100 the added weight and leverage is noticeable. I have no doubt, even with the regear, the little Pickup will feel the big tires. But I just have to do it... just gotta see it and play a bit with the 33s.
