Tires are 265/75/16's, I want to jump up to 285/75's next. I'm not in a hurry, thats just what everybody around here runs on the interstate! It just "seems wrong" to run an ENGINE almost at redline for so long....then again this is my first diesel, on the + side it sounds great with a 4" open turbo back at those speeds!!!! I get 18.5mpg avg most of the time, if I slow it down to around 70mph I get 20.4 avg.
