I have had 3 sets of 285/75/16's and one set of 265/75/16's on my 07 classic LBZ duramax. The slight increase in fuel economy was not at all worth it for the stance and traction sacrifices. Granted the truck is tuned (stock trans/air) but still, it would blow off the back end unbelievably easily with the 265 wide tires. I picked back up some efficiency when I switched from 285/75 firestone muds to my current 285/75 Michelin LTX (probably the only tire I'll run moving forward). I won't run another set of 265s personally and a lot happier with 285s over the last 140k miles. Let me see if I can find a pic on 265s
