I bought a set of max tax after getting stuck in the sand at the beach in our truck/camper. I never needed them until a few weeks ago. We were chukar hunting in Northern Nevada. We were way out there. The dirt roads were snowy and muddy. We were on a narrow dirt road with a deep rut on one side. We ended up sliding into the rut. I thought would never get out. We positioned the max trax upward and outward from the rut for the front tires and they worked beautifully. Had we not had them we would have been there for days while we waited to get a jeep with a winch out there to pull us out. I thought about going with the cheaper brand but when you need these things, things are already going bad so better to go with the real thing.
