I feel it helps to keep a trailer from sliding off to the side when on a sloped trail or road. On the flat, not sure it helps much...
Might help on a big, heavy trailer--small utility trailer, probably not worth the effort.
we always chained one tire on the trailer coming out of the woods in Idaho,they wanna slide off the road if there is any angle...better to use them than not
