I am in a similar situation. I have been researching a lot on wheels and tires. I have gotten close but could use some insight.
I have a STOCK 2019 Ram 1500 5th Gen Big Horn Off-Road Package - My OEM 20" wheels will stay with my winter Nokian Hakkapeliitta 10 tires, which I plan to run from December to March. Here is what I have found so far:
KMC Terra Wheels - 18x8.5 0mm or -10mm offset (Any thoughts?)
KMC Wheels has been redefining performance on and off the asphalt since 1995 with the relentless pursuit to confront possibility.

And for a more OE look, I like the RTX Novi - they appear to only come in 20"
The Novi, with its aggressive presence, fits perfectly Chevrolet or GMC trucks. The seven spoke design embellished with interlocking patterns are inspired by the Chevrolet and GMC truck body designs. The all season finish is winter-approved and gives added protection all year round. The Novi...

For Tires, I was looking at the Nokian Outpost nAT 275/65/R18 ... Alternatively, I would consider the Falken Wildpeak AT3W or see if I can get the Wildpeak AT4W. Does anyone have thoughts on tire size? Should I consider going slightly larger? If I went with 20" wheels, I thought of going with a taller tire 275/60/R20. I do not know when the BF Goodrich KO3 will come out so I have not considered it. I want an all-terrain tire that can be used in the winter shoulder seasons before I switch to the studded Nokian Hakkapeliita tires.
Nokian Tyres Outpost™ nAT offers supreme traction in all conditions, extreme durability and puncture resistance, and increased service life so drivers can extend their terrain, toughness and travel.

I have also struggled with what load rating to choose. Should I go with an LT tire (123S) or would I be fine with a 116T. I have not had any issues with the stock Falken AT3WA's which are only 113T rated. They just ran out of tread. My truck is mainly used on the highway commuting to work. I do tow a 21' travel trailer ~3500 lbs and load up the back to go camping. I also do light off-roading mainly on forest service roads.
Thanks
