New Tires
I done and made my choice and purchased 4 Sailun S637 tires for my Montana. I may have done the wrong thing and I guess time will tell. I'll keep you posted if I have any problems.

I have just been through the tire selection process. What a stressful event. I have read most of the postings on this site.
I have a fifthwheel with a GVWR of 24,000 pounds. It came with Goodyear, load range D, 65psi tires with a load rating of 3000 pounds per tire. When I ordered it I was told that due to my wheels selection, they could only put on the D range tires. Thus they derated my 7000 pound axles down to 6000 pounds. I always felt like I was running right at the edge of disaster with those tires. I did weigh the trailer and I was right on the edge of capacity. With the Marathon tires being 10 years old but showing no signs of deterioration I still felt they should be replaced. Early in their life I did have one failure. But, by the time I caught the failure all that was left of the tire was the bead and some of the belting. Subsequent to that failure, the tire behind it developed a bulge in the sidewall. This is a tri-axle by the way.
I looked at the Carlisle RH, 235 80R 16 which would be a direct replacement size. The rims on my trailer being only good for 65 psi would need to be replaced too. A look at the Carlisle website revealed a statement that they claimed their tires were good for 1-3 years and about 8000 miles. I looked at the Michelin Rib tires but was turned off by their website stating that any tire used for trailering was not warranted. So, I went to look at the Maxxis tire because I had read good about them. I also looked at the Goodyear G 614. Warranted for 4 years; they have a good reputation on this site for trailer damage repair. They are good for 3750 pounds at 110 psi. I ordered 6 and new rims; good for 3900 pounds and capable of 110 psi. Rims were hard to find in my bolt pattern and lug bolt size in Aluminum.
I considered going to 17.5" wheels but at $250 per wheel, I stopped looking when I saw that price.
So, the search is over. $3300.00 and like a lot of you folks, I hope that I did the "right" thing.
