I'm wanting to get a feel of how the 255/85 or 255/80 look on this generation.

Note what make your tires are along with the wheel used and the amount of backspacing.

 

Been following your thread on T4R and I think it has convinced me to go with 255/85's for my next tire. I think that size with a wheel spacer would look great, and do much better on the MPGs than a 285

 

Good Deal! If you have the larger flares you might want to try going with a wheel that has a fair amount of offset and then add spacers to that. I think a 4" backspaced wheel with 1.5" spacers would be where it needs to be (sticking out slightly past the flares)
