| Yes, they tend to be rated by tire size, not chain dimensions.
You could start with a piece of baler twine (or chain) 20 or 24" long. Drape it over the tire with the ends hanging down the same on both sides of the tire. Measure the distance to the axle center. That's the radius of a circular side chain, that radius times 2 pi (6.28) is the minimum length of the side chains for that length cross chain. You probably want 4 to 6" more length on the side chains. I have a set of chains I ought to do that to. Last time I had them on the MF-135 they were hard to get tight. I think maybe I should prune them to fit, maybe loosing one cross chain to make them easier to handle and to maybe not need bunge cords crosswise to get them tight.
