Based on the information provided directly by Sailun and my tire dealer, I have bought and installed the Sailun's.

The S637 is designed to operate at various pressures based on load, thus the variable inflation chart. I don't need maximum allowable pressure and I was assured running them at a lower pressure will not overheat or affect them adversely in any way.
I read somewhere that these tires were designed as an LT but downgraded to an ST to meet the requirements for trailer application. They are a beefy tire with thicker side walls than any other tire I've looked at.
I'm confident in my choice of tire and the pressures I will be operating them at. I have an infrared heat gun I will be checking them with to monitor.

Great choice. My first set of sailuns were LT tires. I bought another tire from them earlier this year and it said ST on it . I couldn't see any difference in tires except the LT's were 3750 pound rated and the ST tire was 4080 pound rated. Both have the 75 mph speed rating. I'm surprised your wheels aren't 3750 pound rated. Mine are stenciled 3750 lb on the back and i have 7,000 pound axles on 8 lug wheels. Have you looked real good at the back of the wheels? Your 5th wheel could certainly use the heavier tires you bought. Good luck.

As for my Cardinal 5th Wheel, GVWR is 15915 lbs. Assuming I add my loaded dual axle weight of 12544 lbs and my loaded pin weight of 2794 lbs for a total loaded 5th wheel weight of 15293 lbs and subtract that from my trailer GVWR of 15915 lbs, I'm under by 622 lbs. As I only have my rear axles weighed in total, I can only assume if I divide by 4, I'm at 3136 lbs per wheel. According to Sailuns load capacity chart for the ST S637, I'd be good for 3640 lbs. at 80 psi.
I have the 8 lug wheels and am pretty sure I have the 7000 lb axles.

I have one wheel and new tire mounted and left to put on. I'm going to have a closer look at the back before I do.

I had to wait for some new lugs. I learned a valuable lesson! Don't use a 12 pt. socket with an impact wrench on the cheap chrome covered lug nuts. I rounded them off and had a hell of a time. The new lugs I have now are chromed solid ones. I also bought a 6 pt. impact socket. Sheesh! Some times you have to learn the hard way!

Trying to keep up with this thread.... so the Dealer mounted and balanced your new tires on the existing rims and you are putting them on yourself and rounded off the cone nut with an impact wrench?

Yup......it's a long story.....

Well......Here's the readers digest version.

I work, so getting my 5th wheel to the tire dealer is a pain in the a--. Have to air up truck tires and air bags take it down there during working hours, have to pick it up during working hours, drive it home, back it up a 12% grade driveway about a block without a rear camera around a brick lamp post while not falling off a rock retaining wall and into my side yard without backing into another rock retaining wall at the end of the parking spot.

Somehow, taking the wheels to them two at a time seemed more simple.

I seemed to forgot you are from Canada so why am i talking about heat lol. You certainly made a good choice and 80 psi should be fine. With your 8 lug wheels and your gvw over 15,000 lbs. i feel certain you have 7,000 lb axles. All i have seen on 6 lug wheels is 6,000 lb axles or 5200 lb axles. I bought a milwaukee 1/2'' drive electric impact for my rv so if i do have a flat then it would be much easier to break the lugs. It has a 700 lb reverse for the hardest nuts. This is as powerful as my ingersolran air impact. Don't forget to torque your wheels after 50 and 100 miles. If you have 9/16 lugs then the recomendation is 120 to 130 lbs and 1/2 '' lugs i believe it's 100 lbs. Safe Travels.
