LT's
A LT235/85-16 E 80 psi has 3042 lbs capacity for 6k axles and smaller.
A ST235/85-16 E 80 psi can have 3640 lbs capacity for 7k axles.
A LT simply isn't up to carrying those heavy loads.
The OP didn't say if his trailer had 6k or 7k or 8k axles axles.
Sailun S637 has gone after the commercial trailer market (regional service trailers) with a ST235/85-16 G load range at 4400 lb capacity and more importantly is a 12/32" tread depth for more mile of service. These tires are popular with trailer owners who have 7k or 8k axles
The ST235/80-16 G 4080 lbs and has 10/32" tread depth. RV folks seldom actually wear out a tire so a thin 10/32" tread works fine.
OP ....the 235/85 tire is around 1" taller which will raise the trailer about 1/2".
Sailun S637 service record is tops with all types of trailer owners.
