Finally got rid of the stock 255/75/17's and upgraded to some 285/70/17 Nitto Terra Grapplers. I really like them so far. They're not any more noisy than the stockers but look MUCH better. I've lost a little gas mileage though. Probably 1 to 1.5 mpg since they're bigger and heavier.
The pic in the rain with my daughter there is with the stockers on it.
