I'm in the same boat with my #2 truck. Delivering RVs with it this year has totally trashed the rear tires in short order. The tread went away so fast, I couldn't see the point in rotating them. They are OEM Bridgestone 773 tires that were popular on GM trucks and vans. I have 2 more new ones I will use on the rear when the two on it are done.... then maybe I should quit doing RV transport with the truck.
Truck #2 is a 2006 2500HD with a D/A, which I put OEM sized tires on when I bought it in February (got rid of the oversize, extra wide tires with some take-off OEM tires I found on Craigslist).
I will probably go for Michelin tires when the time comes to replace them. I had a set on my 2002 2500HD and they were good tires, but I didn't have a truck camper back then, just a toy hauler.
On truck #1 (2009 Dually Silverado, with a D/A) I put on some Cooper AT3 tires, late last fall. I didn't want something quite so aggressive in an "all season" tire, but my choices were very slim due to the size tires used on 2008-2010 GM dually pickups. The AT3s seem to work good in the snow, and they are pretty quiet.
I only have about 4000 miles on them. Dually didn't go on any big trips this year. Poor thing is getting neglected in my driveway.
I'm pretty partial to buying tires at either Costco or Discount tire because of their ease of balance/rotations with numerous locations. Between the two, Discount is preferred due to their additional road hazard warranty, which has saved me from buying a new tire several times.
I'm not sure how plentiful Discount Tire stores are in the eastern half of the US.
Truck number 3 is a beater 84 K20 which uses pizza cutter size tires. I found a nearly new set of Goodyear Wrangler Duratracs on CL. They are kind of aggressive, but for the uses my "farm truck" sees, they are appropriate.
Goodyear has some decent offerings too.
