Big Dog has a good idea.
I am going to measure mine as well and include the tire size as the chain length will change according to which size is on the rim I would think.
By any chance do you have a pic of them laying out on the floor? Is there a name brand? Not important so much as maybe the pic.
I will take a pic of mine as soon as I put the chains on.
We are currently getting snow - about 1 inch down already, but it probably won't stay yet. This is the second time this week and no accumulation left from the previous. Sooo, my chains won't go on for a while.
And, anybody else out there who has chains, and would like to donate a pic and measurements, that would be wonderful.
