The Ribs and the R250 have 3042 lbs of capacity and don't match a 40' 15500 GVWR trailer with 7k axles ..... if the trailer has 7k axles

It does have 7k axles and I agree Jim. I would not use a tire with a 3042 rating.
Tires.... for such a simple device it sure can be a confusing subject. I am still having a hard time believing that in this day and age when there are so many large 5th wheels on the road that there are so few QUALITY tire options out there. It just boggles my mind. I hear of so many people using Ribs with great results on big trailers yet they are "only" rated at 3,042lbs and I am just not willing to take a chance running a tire that is rated that low. It may be the greatest tire on the road but what if..... what if it fails and you have an accident and someone gets hurt and your found guilty of running under rated tires.... what if?

Yes there seems to be lots of RV trailers out there. But in the grand scheme of all vehicles there a very few RV trailers. RV trailer tires are a niche market. That's why there are lots of issues because there are not many tire choices. Many end users don't understand RV tires.
The scenario gets even more complicated because the OEM tires are often cheap marginally rated tires that need to be replaced from day 1.
Go into your typical tire store and talk to them about RV trailer tires and you will not get a lot of solid answers.
The Goodyear is truly the only choice for a heavy duty dedicated RV tire. Sailun tire has come along and provided another option.
The are a few good LT choices, Duravis, XPS, ribs and commercial T/A's.
Nevertheless if you need a heavy RV tire for a rigs in the 15K GVW range your choices are still somewhat limited.
