I have had both tires on seperate sets of wheels for a good deal of time and IMO the KM2's ride so much nicer on road in 255/85/16 E load than my 265/70/17 C load Duratracs ever did. I like the KM2 so much I initially bought them as a "wheeling only tire" and once I put them on I haven't gone back to my Duratracs in over a year (granted I haven't driven it in 6 months
).....they feel so much stiffer and seem to hold corners better on road as long as it's not snowing, raining, or slick.
That's said I think anyone getting MT's who never offroads because they 'look cool' is just plain silly
Most guys who know anything about trucks and off-roading can spot a mall crawler in minutes and believe me the last thing we do is tell them nice truck or give them props. It's actually the exact opposite and we bash all the useless bolts-ons and ask them when the last time they got it dirty was....or better yet have a girl we are with ask them, and when they stutter to answer, the chick tells them her trucks got more offroad balls as she walks away (that happened at the last offroad show I was at and boy did we all crack up).
Get a AT for better mpg, better practicality, longer wear, and in closing stop fronting. No one likes a fake
