For ATs I'm a cooper at3 fan boy. 97 dodge 2500 gasser with 315/75/16s, 78 f150 with 315/75/16, 73 f250 235/85/16 and have talked a few people into them. Great price, great tire. Now that being said on my 06 cummins I had to think long and hard for tires. The problem with the 17s in my opinion is your weight rating goes way down on them in the 315 size. I had a set of BFGS on the truck when I bought it and I would max out the tire weight by hooking up my trailer. So I decided to drop down to 285s in the Nitto Duragrappler. For a truck that is tow only this tire rocks. Great mileage out of them for what they are on, ride good, do ok in the snow and rain and for a highway tire when you get them in a 285 they look pretty darn beefy.
Make sure you look at the weight ratings, not just the load but the no kidding lbs. and do the math. My next go around ill step up to 18" wheels and go with 35 12.50 18s to get a better weight rating in an AT and have the more aggressive tread vs. the dura. Just something else to think about before you make a 1200$ mistake.
