Being from a state where we never have a need for chains or studs (and they are actually not allowed here in LA), my first thought was why would you need them on a trailer......since it is being towed. Then I realized you would need them for braking purposes, when you would need it to maintain some form of traction.
Can you snowbirds educate us swamplanders, if this is a correct assumption, so should I ever get to a place where the temperature is below freezing.
