Yooperdave's thread reminded me of the challenges of finding front chains for my 3720. One of the things that might make it easier is knowledge of alternate sizing that is the same, pretty darn close, workable, or can be trimmed to a great fit.
First there is the issue of the various numbering systems.
Second it seems that some minor variations in dimensions may not matter:
1 same overall diameter and width but different rim size- would not the chains be roughly the same but cover a different percentage of the sidewall? And thus workable
2 same overall diameter but width differs slightly- seems like often they would drape more or less over the sides. Again workable
3 chain for slightly larger diameter tires- when can they be cut, and when not?
Thoughts and experiences appreciated
