At Costco, Michelin XPS rib are $246.99. Price includes:
Shipping & Handling, Mounting, Balancing, Lifetime Services, Nitrogen Inflation, New Rubber Valve Stem, Environmental Tire Disposal, and the Costco Road Hazard Warranty.
3042 lb load rating at 80psi. The load rating for trailer tires is greater because there is not the requirement for as great of a margin of safety compared to tires that will be mounted on a vehicle carrying humans. Therefore, you really don't have a greater margin of safety by using a trailer tire with a higher load rating.

Since you have the 110psi wheels, you could go with the Goodyear unisteel G614 RST load range G with 3750 max load.
The Goodyears were used to replace some Chinese made Hi-Run tires that came on our trainer's LQ Horse trailer. The Hi Runs were being lost at the rate of 1-2 tires per trip! Not had a single problem since replacing them with Goodyear G614 tires in over a years towing.

So I could use G-rated tires, if you recommend any of those as being better in my circumstances.
I've had problems with Goodyear Marathons, so I certainly wouldn't recommend those to anyone. I don't have any experience with the Goodyear G-614s, but I would be leary of them only because of my experience with other Goodyears.
I've had great service from various Michelin tires for the last 30 years Never a problem with any of them. The Michelin XPS Ribs on my F-250 are the best tires I've ever had on any vehicle, bar none. Michelin rates them for "all position" service, including trailer service, and very few LT tires have that rating. The rare Michelin Energy LX4 tires on my Honda Odyssey have been outstanding, and I just bought the third set for it and stored them in the barn because they are hard to get. So I can recommend the Michelin XPS Ribs for your trailer with no qualms. I think you'd be happy with them. They give you more than a 10 percent fudge factor for weight capacity, so if it were my 5er I'd probably go with the XPS. But if you want more fudge factor, then the Goodyear G614s are an option.

I special-ordered it new and plan to drive it until it quits.
I was fed up with junk made in China ST tires. So I narrowed my options down to these three LT tires:
Michelin XPS Rib
Toyo M55
BFG Commercial T/A
Ultimately, I chose the BFG Commercial T/A due to their price, availability, and the fact they were made in the USA (some production runs are made in Mexico, but mine are all domestic).
Be sure to review the tire specs for whatever tire you're interested in. The Michelin XPS were slightly wider than the others, which ruled them out for me.
I don't have any experience with the Denman brand, but the few I have seen on boat trailers were made in Mexico.

they are worth every penny and the costco coverage is good never used it but i hear they are nice and helpfull and will do all necessary to get you moving again

If you buy the michelin xps rib at costco, be sure to save your receipt, because you can get rotations and rebalancing for the life of the tire at no extra cost, but you must show the receipt.

I looked into the Michelin XPS Rib at one time, and there was a problem with the measurements. I forget exactly, maybe it was the diameter, since I only have an inch of space between the front and back tires. I'll look at it again.
And I have heard about different safety standards for LT and ST tires in load rating, but I think probably 3042 compared to 3640 still gives the advantage to the Denman's. Denman's are 10 ply, I don't know about the XPS ply rating.
I, too, am leery about Goodyears. If the G614's are any good, they are the only good ones for trailers that Goodyear makes.
I would think that most tires made especially for trailers (ST) would be better for that use than most tires made mainly for trucks (LT). Nobody here has said anything bad about the Denman's yet.
Denman's are 10 ply, I don't know about the XPS ply rating.
The XPS are rated as 10 ply as well. Remember that is not the number of plys but a measure of the strength of the sidewall using some ancient polyester cord as a measure of ply strength. The sidewalls on the XPS are steel and are considerably stiffer than other tires. Note that I am not talking about the "belts" but the sidewall. I cannot find out what the Denman sidewalls are made of.

It is actually the air in the tire, not the tire itself, that supports the weight. That is why any LT tire with the same size and the same psi inflation will have the same weight rating, and any ST tire with the same size and same psi inflation will have the same weight rating. The tire holds in the air, but any two tires with the same size and psi inflation will have the same weight rating. ST tires have 20% greater weight rating than LT because there is a lower safety rating for vehicles not carrying humans, also, because steer tires have greater stress and heating than trailer tires that just follow where they are being pulled. The amount of air in an ST tire of equal size and ply rating is the same as the amount of air in the LT tire.

The safety rating seems like a great explanation of why the difference.
I too will need by 4 new tires for the trailer in size 21585R16. I am between the BFG Commercial or the Michelin XPS Rib. I love the Michelin tires I have used but the price for the trailer seems high. I need to think about it.
As far as COSTCO goes, I love their service. You do not need a receipt. As long as you have your memeber number, they can look up your purchase. Rotation, balancing, flat repair and warranty is included. The warranty is great. I will always try to buy tires from COSTCO.
Hope this helps,
John

So does everyone agree that 3640 load rating in an ST is the same as 3042 in an LT, or is that just one of those stories that gets passed around until it is accepted as fact?
The XPS Ribs would leave me with .65 inches between front and back wheels, which I guess is doable. And they cost $229 + 13 mount/balance at Discount Tires, about $100 more than the Denman's at an independent. They also weigh 12 lbs more than the Denman's, which I guess is a good thing.
The GY G614's cost $355 each (ouch) from Discount, weigh about the same as the XPS, but are 14 ply.
The BFG Commercial T/A's are LT's which are not all-position (I think) and, according to Smokey, that's not good on a trailer.
I use G rated (Goodyear G614 I think) tires with 80 psi wheels. I only inflate to 80 psi. That more than covers my capacity needs without the expense of buying 110 psi wheels. Check the tire weight rating charts to see if G rated tires will meet your needs at 80 psi.
