His specs are;
GVWR: 15,000#
GAWRs (2): 6,200#
Tires: ST232/80R16E
There is no strong reason for him to increase tire size. The current size and load capacity at 80 PSI are providing about 12% of load capacity reserves above GAWRs.
However, using a replacement size ST235/80R16 LRG inflated to 90 PSI would increase his load capacity reserves without changing the designated tire size on the trailer's placarding. (The PSI limit on the current wheels would have to be verified for the higher PSI capacity LRG tire).
