Or, put another way, do they make an 80 PSI tire with a 4,000 lb. load rating?I'm not saying there isn't but I've never seen a 16" trailer wheel that was 4000 lb rated.
Now the 17.5" trailer wheels can handle that much load and 110 psi which is a good upgrade for folks with a heavy wheel loads and 7k axles.
To minimize all compatibility and safety issues on a very heavy rig, especially toy haulers, 17.5" is probably the way to go. I'm guessing the larger diameter 17.5" tires/wheels have the potential to create some clearance issues on units that originally came with 16's though.

I confirmed with local tire dealer today. He says that it is no problem running 110psi in that wheel with those tires. He states that overloading the wheel weight rating is what will cause wheel failure. I've dealt with him for years and he knows his stuff. I'm not saying he's right or wrong, but i do value his opinion and feel it trustworthy.
I also know between this forum and the Jayco forum that several are running the same setup on the same wheels.
This is the correct answer. Wheels are designed for a load limit, not a pressure limit.
But all the "experts" around here won't agree.
Even real experts like a wheel manufacturer/axle manufacturer/tire manufactuers/rvtiresafety.com and many other sources disagree with that statement.

WHEELS & TIRES - What tires can I use on these wheels?
Wheels and tires must be matched. The wheel will have a label stating its rim diameter, width and contour. The tire selected must be approved by the Tire and Rim Association for use on that particular size wheel. The tire capacity selected should not exceed the capacity rating of the wheel. The tire inflation pressure must not exceed the pressure rating of the wheel. WARNING - The use of tires that are not approved for use on a wheel could result in explosive separation of the tire and wheel and could cause a serious accident.
Load a 16" 3100-3200 lb rated wheel to 3200 lbs and then add 110 psi can and has resulted in a split bead or a cracked valley. BTDT more than once..... and saw lots of examples of using pressures above the wheels max psi ability when I was on the road.
Lots of 16" trailer and truck wheels out here with 3200-3600 lb load rating and a 80 psi max rating.
Don't over pressure a tire or wheel. Sooner or later it will bite you in the butz.

IF wheel is stamped for load rating of 3200#, it CAN equate to what tire one can use. Example.: An E rated Michelin XPS RIB has a weight rating of 3020 pounds at 80 psi...OP's wheel is rated 180# more than that, all is good....If you go to a G rated GY G614, rated at 3750# @ 110 psi, which is over wheels rating by 550#...wheel won't take 110 psi..so wheel rating can be looked at both ways..
in know you can run lower psi in tire's, but one has to also take into wear on tires and when turning unit around and "skewing" tires in tight turn.

You need to determine the PSI rating of your wheels. You also need to determine the psi rating of your valves.
Often the psi rating is stamped into the inside of the wheel.
Don't run more than the rated PSI on the wheel. IF you have 85 psi rated wheels, run your S637s at 85psi. They can operate at lower psi ratings, but obviously you get decreased load capacity. Still, it's likely a much better tire than what you had from the factory.
Wheels, tires, and valve stems all need to be rated for the PSI you put in them.
