I have a stock GMC 2500HD 6.0 4x4 with 4.10 gears. It still has Bridgestone LT245/75r16 tires on it. It gets on average 12.9 mpg per the computer and is fairly revy on the freeway.
I am trying to decide between LT235/85r16 and LT255/85r16 tires for it. I am leaning towards the LT255/85r16 in Toyo M55's or something similar. If I go for the LT235/85r16 I'll likely go BFG K02.
How much will by MPG suffer or improve changing to these tires?
