I am ready to put on new tires (06 prius). I Want Goodyear TT's. What is the difference between the tires mentioned above? Why do most posts recommend the 60's over the 65's? The 65's are taller........but wouldn't they actually give me less rotations per mile thereby cheating my odometer just a smidge? With the 60's I believe I would be cheated in the odometer just a bit, if i understand the sizes correctly.
