I've searched and read a ton of posts and saw one about 255/55/20 and another about 255/50/20... I'm just not seeing confirmation it works. Can I use a 255/50/20 on a '13 stock wheel? I may not get away with using an all-season tire year-round in my area, NW CO, but I'd like to go as narrow as possible. I see 275/45/20 as an alternative but not discussion around a more narrow tire. Our commute is also a paved 12 mile winding road so would a 255 width be a significant handling sacrifice? I appreciate any help!

Sir, I would imagine that stock tire choice is made by OEM engineers and influenced by such factors as:
Power and weight of the vehicle, amount of rubber in contact with the road surface needed to assure secure grip. Once you start walking away from OEM spec, it may influence handling of the truck, I would imagine little here little there may not have a significant effect but perhaps tire specialist could chip in. Also, if you looking for a tires on major tire selling websites, please look at rim requirement for the tire size choice you're considering to make. RRS has a 9.5 inch wide rim, I believe, and that should be within spec of the tire. Also, please keep in mind that your spare is likely 275x40x20, should you ever need to use it, it has to match the rest of the tires in outer diameter otherwise differentials may be very unhappy about that, like really really sad.

I have used 255/55-20 (which rubbed slightly at full lock and high suspension compression), 265/50-20 with no rubbing and I am currently using 275/45-20 because I wanted the Cooper Zeon LTZ, which I really like.

Just for reference, I'm using 285/50/20's (Nitto Terra Grappler G2) mostly just fine. Literally right at hard lock only, the insides of the front tyres barely rub on the end of a structural member that stupidly protrudes into the back of the front wheel arches. It looks like that member could easily be cut back a little then welded flat with no negative consequences (which would totally solve it). I guess I could also just fit spacers. I just haven't bothered with doing anything so far because I hardly ever actually need full lock (even offroading) so its not a problem I really encounter.

I'm using the same size but with regular A/S tires and I hate these. They rub when I take sharper turns at higher speeds and at access. I was planning to go to the 265/50/20's because those were on mine when i bought it. I tried the 275/45/20 or something AKA the OEM size and i wasn't a big fan of those comfort wise. The 285/50/20's are great for running over potholes which there are a lot where i live but the 255/50/20's are perfect blend if you don't want the bigger profile

I don;t know why but my Grappler G2s clearly aren't rubbing even slightly as much as your A/S's.

I have the same setup, the Nitto Grappler in 285/50/20 and no rubbing except at full lock. Sometimes when i jump the railroad tracks ill get a little rubbing but nothing scary.
