Not sure and not sure. The truck is 25 feet from me but I'm sitting at my office desk for another couple hours working on tax returns. Sorry. They assure me it will work so I'll try it when I can do so. What I have is stock 2011 Dodge Ram 3500 Dually steel wheels.
Now on tires
Stock tires are 235/80-17 which are about 31.8'' *9.3'' on 17'' rim
What I want are 275/65/20 which are about 34.1'' *11 on 20'' rim
So width wise each tire is then 1.7'' wider then stock and stock is actually seems pretty small in the huge wheel wells and seems to have plenty of room. So the rear axle will have a total of 6.8'' total inches more of rubber to fit somewhere.
This will be all about the offset and rim width.
This won't be much then guys putting 265 or 285 tires on 16 inch rims on duallys. So I'm not to worried.
I promise when it happens, pics will be posted.

Muffler city for XDS2, they do not stock the tires but get them from tire warehouse/distributor. They are quick and more then fair on prices. I asked them inflate them 100 PSIG the last time. This took them awhile with their compressor. Normally I run 100-110 PSIG with the camper on.
The Rickson 19.5 where ordered in directly via surface freight. Bought 5, as during the summer am not going miss 5 weeks of our short fishing season waiting for another rim.
Only problem I have had with the rims, is with tire valves. They were making bubbles around where they sealed to rim. Rickson recognized they had problem and sent me 5 replacements form different manufacture. I make it practice of checking tire pressure as running very close to F350's 11,500 GVWR.
We have been using Rickson 19.5" wheels and tires for 8 years and 88,000 miles. We were the first ones to discover that they were not able to be aired down for use in the very soft sand at Assateague Island. We use a set of 16" Nitto Dune Grapplers on stock Ford wheels for our many forays on the beach and use the Rickson setup for everything else. The 19.5's have worked fine off-road in gravel, dirt and snow along with being very comfortable on the Interstates on our several cross oountry trips. I have Dunlap tires at present which have performed well, I'll be considering replacment shortly, although there is still good tread showing, they are of an age to be suspect
Our tires are "H" rated which is, I think, good insurance against failure with the very heavy loaded weights we are dealing with.

The total loaded weight of my truck was actually 10,200#.
I WANTED to increase the carrying capacity just for extra peace of mind. I went from 3415# on the "E" tires to 3900# with the "G" tires. The axle is rated for 10,140# so I now have a lot of "cushion" on the rear axle where I needed it. It just makes me feel better knowing the wheel/tires ratings now are well over the true weight that I am carrying.
I also have added Stable Loads and Timbrens as well as a Helwig "Big Wig" rear end anti sway bar. It is not the same truck I started with and I feel better! And it rides better loaded.

I'm in the same boat. I WANT to increase my carrying capacity, for safety and peace of mind . I don't like being just under by a few 100#'s, even 600#'s. Besides I need to tow a small cargo trailer (5x8) once in a while. I have the air bags and stable loads, just need to decide on tires, or wheels and tires. Dodge dealer says I CAN install 285's on the factory wheels with no issues. Only Nitto and Hancook make a 285 17 with a 3750lb capacity, which weight wise would be sufficient. But...is this sufficient overall? I don't know.
If your Dodge dealer is telling you to install 285 tires on the stock wheels, he doesn't know what he's talking about. The stock wheels are too narrow and lack the weight capacity to match the weight rating of the 285 tires.
Go to any major tire manufacturer website and look up the wheel width specs for their 285 tires and you will see what I am saying. 8" is the minimum wheel width spec for 285 tires by all the major tire manufacturers, that I am aware of.
Also, it doesn't make any sense to spend the money on high weight capacity tires just to run them on rims that don't have an equal weight rating as the tires. May as well just keep using the stock tires, since you're not accomplishing anything by using the stock wheels with the heavier rated tires.
That makes sense. I've read till my head is spinning and I'm no closer to buying.
It seems to me that if I have to buy rims anyway, I might as well get 19.5's, but they're best suited for hyw, may have issues on sift surfaces. However, if I get a 17" rim, 8" wide, then I can stick to a 285, which would handle the load and multiple surfaces. Either way, I need new rims. But, if I get 285's I will increase my overall height of the vehicle. If I get 19.5" I can stay with a tire that keeps the profile at my current height.
Isn't there a rim size/tire size that will handle my load, and handle multiple surfaces, without increasing overall profile height and in a rim size that will have a better range of selectable tire sizes, weight loads, and tread patterns, like maybe 18" or 20". How would these sizes compare and what would be the advantages and disadvantages with either of these sizes?
I know a lot of questions and issues. I just can't find any tire dealer up here that understands what my concerns are and why I'm worried about it all. They just want to put me into a new set of 285's right away.

I called Muffler City. They want to put me into 285's, say this is my best option. They said I could do 19.5" but it's over kill for my circumstances. I wouldn't think so, but...
I just hate the thought of having to change out my wheels/tires and swapping them each fall/winter. I know, I know, that's what we do up here, but it's such a pain! It may be the best solution. With rainy season coming in, and all the driving back and forth to the Kenai, Homer, Seward, etc... I plan on doing, I want to get this done soon.
I hope Rickson got all the valve stem issues worked out. I'd hate to spend those big bucks and have issues.

Thanks for the comments. It helps to hear experiences from others, it gives me an idea of what I'm getting myself into. It looks to be that no matter how much I research this issue, the best solution is leaning towards the 19.5" and keeping my stock's in place when the TC is off the truck.

Thanks all!
Keeping the stock tire diameter, assuming that's about 31.5", about 3400-3500 lbs per tire is about the most load capacity you can get in a 16", 17", 18" or 20" LT-E tire.
265/75-16E's are 3415 lbs per tire and 265/70-17E's are about the same, if I remember right. To maintain the same tire diameter in an 18" wheel, that would be size 265/65-18E, likely rated around the same 3400-3500 lb range.
265/55-20 would a size with a similar diameter in 20" wheel, though I'm not sure that size actually exists in the market. Most of the 20" tire sizes I've seen for trucks are around 33-35" diameter.
If you're willing to go up to about 33" diameter, which isn't that big a jump in tire size, there are a few tire sizes in 17", 18" and 20" wheels size that have 3600-3800 lb weight ratings.
If you're willing to go up to 35" tires, which is a significant jump up from the stock diameter, there are tires with 3700-4100 lb weight ratings in 18" and 20" sizes.
Tires to look for in these higher weight ratings and larger sizes are BFG All Terrains and Mud Terrains, Toyo All Terrains and Mud Terrains and Nitto Grapplers.
