All of the different metric sizes are confusing, because its not just the first number but the first and second that determine the actual tire size. A 255/85 is a 33" tire and a 305/70 is a 33" tire and a 285/75 is a 33" tire but they are all different widths going from 10" to 12".

The rim size also comes into play. A 285/75r16 is equal to a 285/70r17

Has anybody here gone with the 265/75-16? Should one expect faster wear rate on the tires since there is less surface area to support the vehicle's mass compared to the 285? Not wanting to get into a theoretical debate here--anybody have experience with either in terms of fuel economy differences from the stock LTX?

I went from 275/70r16 to 285/75r16 and can hardly tell a difference in fill ups when gas is at a relatively constant price around $3.12/gal. I put about $25 in and go to the same places and gas mileage is close to the same. I have a routine driving schedule. I'm in the process of figuring my real miles per gallon this week.
Update on real MPG is 12.79194 on 285/75r16
