Many of you may know, but if not, here’s a quick refresher. As of October 1st, 2019 all CMV must carry tire chains. At FV Martin, we carry them all year round. But, if you are hooking up to a trailer or driver a truck that is not typically yours, make sure they have tire chains (and chains that fit). Especially, if you are in a different truck and heading up into the woods. If you are unaware of the chaining requirements, see below;
