    swapping up from 245/75 to 265/75, does this effect the odometer reading? Am i travelling farther than it says? or is that increase in size negligable.....advice? Thanks

    You will have a difference in odometer readings yes. I went with 265X70-16 for that reason. They are almost identical in height with the 245s. Use the "Tire Size Calculator" at the bottom of this page/screen to compare. The calculator gives percentages in difference and height.

    Stock odometer/speedometer reads too fast/ more miles per gallon than real.

    My stock size was 265/70-16 and the speedometer said 70 when I was going 67. I got 16.5 mpg around town.

    My new size is 1" taller: 265/75-16 and my speedometer is now right on 70 at 70. I now get 15.5 mpg around town! But, that is real...
