When I had a Silverado (1500), I'd get asked when I was going to put some "real" tires on it. It came with Bridgestone Dueler HT's. Looked like a car tire for sure, no knobby sidewall, lots of narrow siping on the tread for water. Rode smooth and quiet, and by 35k miles, was fairly certain they were going to last to 60k+. So many folks go for an aggressive looking tire, "all terrain". Some AT's are more aggressive than others, but a "real" tire, IMO, is fit for purpose. A nice highway tire is exactly what that pickup needed.
For reviews suggestions and browsing pleasure, I'd hop on Tirerack.com just to see what's out there for your size and get a sense of what you might want.
