I will be purchasing a TST system before our Disney trip (1900 miles round trip) in November. The 3750 lb rated tires that came on the Fuzion are now 2 years old and have approximately 5,000 miles on them. I will probably replace them next year just to be cautious. Much to delight of the weight police, I will not be using an LT tire. LT just isn't an option with my 7,000 lb axles even though they usually only see just over 6,000 lbs each.

Sure they are. Either the Sailun I mentioned or the Goodyear G614's that I have are LT and are rated at 3750 each. As long as your rims are rated to 110 you are good to go...
I also use the TST system for my camper as well. Lots of people are also doing what has already been mention, that being changing wheels and tires and going with 17.5" combos. You don't have to worry about the weight with them. But, you have to have 7k or 8k axles to do it.

Sailun makes no assertion that their 235/85R16 G637 tire is an LT. In fact they specifically state that in that particular size, the G637 is for trailer use only.
I forgot that the G614 is listed as an LT. Either way, my rims are rated to 110 psi and my next set of tires will be G rated, not E rated LT tires.

I guess. Sailun doesn't say it either way, ST or LT. I'd go with them over any ST tire on the market though. I just think the Goodyear's are a little better and the warranty and trailer damage claim policy is outstanding which warranted my money.
Heartland is one brand that finally listened to consumers and is dumping TowMax tires. They are switching their lines over to Sailun and even retrofitting built rigs on dealer lots with them. Glad someone is listening...
The industry as a whole seems to be stepping their game up a little bit on the tire and axle issue. The higher end trailers seem to be switching to 17.5 tires and avoiding the liability of providing marginal tires on heavy trailers.

I've seen that too. Just last night I was on DRV's site as they have a new Toyhauler line called "Full House" and like their other lines, they come with 17.5's... Along with lots of other high end upgrades.
Both the Goodyear are G rated tires and require rims that are rated to 110 lbs PSI.
That's a bit of a misnomer. The tires can go as high as 110, but they don't have to be there. Thus they don't have to have 110 rims.
I have 100 psi rims and run at 95 psi cold. That gives me 3415 lbs capacity per tire. My trailer weighs wet, 11,240 on the axles, or 2810 lbs per tire, give or take 100lbs based on position.
I use tireminder to monitor pressure and temps. No issues with either.
OBTW, anybody explain why tires are rated so much lower in capacity when set up as duals (at the same PSI as singles)? I don't understand.

That is correct, but since Matt wanted the full 3750 capacity I assumed he would want to inflate them to full pressure.

When the tires flex in a dual configuration, the bulges get pretty close to causing the tires to rub. The more load on the tire, the more bulge. When dual tires bulge enough to rub together, it doesn't take long for total destruction to occur. The close proximity of duals also does not allow for as much heat dissipation.

On a 2007 Forest River fifth wheel triple axle toy hauler I almost bought.. Almost because some dipstick changed out the wheels and tires to ST225-75-R15 LR-D from the spec'd LT235-85-R16 LR-E tires...
Sorry for the fuzzy pic..
The toy hauler. I just purchased and towed home has ST235-80-R16 LR-E tires that look good but are timed out.. I can't afford the G614's this go around, but they will be on it next time unless I can install two at a time starting on the rear axle..
