Got a set of small tire chains for the front of my B2620. I don't see how I will ever keep them on without some kind of tensioner. I have never needed to use them on my big tractors, so I don't know anything about them. I see ones that will fit on the outside of the rim obviously. But there are also some that can be put on the inside, around the axle. What should I try? Does it make sense to do both?
