So I can effectively get the 3.27 rear gear advantage with the taller tires and the 3.45 rear gear. This may have just made my choice for me. The 3.27 with the taller new tires may be too much gear from a stop. My everyday drive may be 80% highway and 10% freeway, but it is broken up by a couple of small towns. And my weekend driving is nearly all in town. If I go with the 3.45 and taller tires and see an FE improvement, I can switch to a 3.27 and go back to a lighter stock size tire when I wear out the current tires. I've only got about 5k miles on them now.
