It looks like most 17" tires top out at 3,195 lb capacity but if you go up to a LT295/70R18 it has a capacity of 4,080 lbs @80psi.

If you want high capacity the LT295/65R20E tires have a 4,080lb capacity that is higher than most 18, 17 or 16" tires.
On a RAM with 3:42 gears going from a 33.19 diameter tire to a 35.1 would not be the best idea. These trucks already have long legs.
If you want high capacity in a short tire for better gearing the 285/65R16C load range E has a 3,970 lb capacity @85psi and is only 30.6" tall.

You didn't pick the wheels you wanted? It isn't hard to find manufacturer weight ratings on wheels. It is important, though, because some 18" wheels are rated lower than the 3640 lbs on the tires.
I agree with all the comments saying 18" is ideal on the newer HD models. 17" aren't rated as well and 20" are more expensive and have a more limited selection.
Nope. In fact, I didn't even see them until they pulled the truck around when they were finished. I didn't care too much what they looked like as long they met or exceeded the load rating, somethign that I didn't have to clean all the time, and did not scream "I am a 17 year old with white Oakley's driving a pavement queen". I believe those were my exact words to him. They ended up being black MB 352's and look pretty good on the truck while meeting my requirements so I was happy.

Who would've thought that the spare is not totally interchangeable?
Check the tire radius, and you will find them similar.
RAM uses LT275/70R18 with diameter of 33.19
and LT285/60R20 with diameter of 33.46
So .27 /2 = .135 difference in radius, so I do not think about an 1/8 inch would be very noticeable getting in and out of the truck.
These numbers on based on OEM Firestone Transforce AT's. Other brands will be similar.
What happened was I broke a belt in one of my tires and wanted to put the spare tire on the 20" rim. Couldn't do it and had to pay for new tire at a place that wasn't cost effective.

When I bought my truck, one of the first things I did was trade out the factory tires for better off road tires. It gets a little sloppy at the farm and deer lease when it rains. My truck came with 20's and the Nitto Trail Grappler tire I wanted was $80 per tire more for a 20" versus an 18".
Not being fond of 20" tires in general, I asked the tire store to put any 18" rim on the truck that the had in inventory that met my stock rim load ratings. The 18" rims cost me about $140 each and I ended up selling my stock 20" rims for $150 each.
