'03 ES300 w/60k miles Just replaced all four tires, and the odometer and MPG calculations seem to have changed slightly. Originally I recorded 27-28MPG on the highway and
21-23 in town. Now coming in at 23-25 and 19-21. Checked a couple of fixed routes that I drive frequently, and they are reading shorter distances than before.Asked the dealer to check the speedo and odo when it was last in, and they say there are not adjustments for tire size. Didn't check the original tires against spec but the new ones are exactly what is called for.
Any thoughts/ideas are appreciated... JS
