Speaking as one that has used chains on my VX I doubt anyone needs them if you are running some type of all terrain or off road tires. I carry a set with me and have never needed them for snow. Ice is a different matter and I have used them for very slick icy conditions that no one should be out in anyway. I have a full set for both the VX and the Jeep but never used on the Jeep and only 2 or 3 times on the VX.
So what have I used them for you ask? Rescue work during winter Association events where chains make the difference. Last year I went out on a truck rescue with the VX. I had the chains with me but never put them on. I was one of three vehicles out of 16 that actually made it to the stuck trucks. In some places we were plowing though 4 foot drifts with the average snow depth at 18”. I am running the new BFG MT’s which are a 1000% improvement over the old MT’s in the snow. There must be a compound change since the tread is not much different. Back when I was running 33” BFG MT’s on the Jeep I always had to chain up on winter runs.
If you live in an area that is prone to ice storms and have to go out then chains are the way to go but you need a full set. Keep in mind you can not drive very fast with chains and there are all the other crazy’s out there to contend with so you would be better off staying home anyway.
I am not sure about all the DOT regulations in every state but for the most part it is either chains or four wheel drive not both as it is here in Utah. If conditions get so bad as to require chains on a 4x4 then the roads get closed anyway. Save your money and by a set of all terrains. I highly recommend the Pro Comp AT’s for snow. I have a set on our Dodge and they been unstoppable.
