Consider this. The chains on my 10,800# Wildwood measure .333 inch. Thats less than a 3/8" chain. Probably is a Chinese manufacture chain of questionable quality and given FR's push on cost control is probably a grade 30 chain. That means that it might have a strength as low as 1900#. The chains bear no markings (43 or 70). To meet DOT requirements, each chain would have to be a full 3/8" grade 70 chain.
I think the chains the manufacturer installs are mostly cosmetic.
With all due respect, I don't think that is a correct statement.
A chain with a material dia of .333" is most likely 5/16" chain. That size of grade 30 chain would have a WLL of 1900 lbs., but a min breaking strength of 7600 lbs. The pair would have a combined strength of 15,200 lbs, which would meet DOT req for your 10,800 lb trailer.
