Still 884 lbs. more than the axle limit 3042 x 2 = 6084

"Like said above... don't need 3420 tires... since the wheels are only 3200... and really... even 3200 is overkill since the axles are the weak link at 5200.."
The problem is twofold. Minimum safety is the trailer manufacturer's decision and to top it off they must certify their decision.
The LT tire you suggest could have also been the trailer manufacturer's decision. We can only second guess why in wasn't used. Surely it wasn't because of availability, it's a widely used size and design and very capable of supporting 5200# axles.
Here in this statement from the tire manufacturer is another problem. It's not just Michelin, it's an industry wide standard that supports all vehicle manufacture Original Equipment selections displayed on federal certification labels.
"Michelin: Never choose a tire that is smaller in size or has less load-carrying capacity than the tire that came with the vehicle."
