Yeah, re-geared, it was the larger 265/75/16, previous owner had about 8k on them, I think the tire shop may have had a deal on them or someone else talked them into the slightly oversized tire, seemed out of character from the otherwise stock set up.
Here's the tire size calculator I used;

Second day on the 245/75/16's and I like that the fuel gauge is slowing down, I've been writing the miles and gallons down for the last 3 fill ups (includes today's fill up), so the next tank full I should get an idea of the fuel (money) savings. I like the obvious pick-up and cornering of the new size/lower center of balance, but the bigger tires did take bumps better, of course I have a good example of a bad road I drive most every day.
