I am not sure if you want to change tire size since all the computer calculations mpg etc and transmission are based on the overall size of the tire. here is a site that calculates the difference http://www.tacomaworld.com/forum/tirecalc.php

What I did was keep the 235/65/17 for the winter and upgraded to a factory BMW sport set of 19" staggard wheels/tires. 255/50/19 front and 285/45/19. It makes it look tough but rides rougher.
