Highway tires
ive seen good things with the kuhmo road venture a/t tires. two guys i work with have had them for about a year and they both drive about 200 miles a day for work and the tires still look almost new. lots of tread on them. if you dont need an a/t tire i know they have good all season tires. tirerack.com is the place to go to get them.
How many miles do you have on your truck? my crappy dynapros were almost completely bald at just about 35,000 miles and i only drive on the highway too. I replaced mine with Firestone Destination A/T's. They are an excellent tire, nice and quiet on the road. i liked the more agressive tread on the A/t's but they also have them in an L/E series that is more suited for on road only driving
You might look at Continental Cross Contact LX. I bought a set for summer driving, about 2/3 highway, and am real happy with them. They are quieter than the Michelins that came on mine and give a great ride. I don't know about mileage since I've only got about 3k miles on them, but they are rated highly on tirerack.
