That regulation is directed at the vehicle manufacturer to insure minimum requirements are met during the certification process.
Not entirely true.
The 567 cert placard mentioned in 571 I pasted also gives direction for subsequent trailer owners looking for a tire for the vehicle with the proper weight.
Roadside enforcement uses the the 567 certification placard to determine if the proper tires are on the trailer in this case. IMO more trucks and trailers out here were in service years before the tire placard.
The LT235/85-16 E tires the OP wants to use will work fine from a weight perspective.
To the OP.
My 11200 lb 5th wheel trailer with 5200 lb axles came with ST225/75-15 D at 2640 lbs capacity. I upgraded to LT215/85-16 E at 2680 lbs capacity. Ran the first set for 7 years and 55+k miles. I now have close to 40k miles on the second set same size and brand. If your trailer has 5200 lb axles the smaller LT225/75-16 E or LT215/85 16 E at 2680 lbs capacity works fine.
Now if your going to stick with a ST tire then as others have said you would be better served to use a higher rated tire with more reserve capacity.
