- Shortening the chains to five links puts the loops for the zipties at the edge of the tread.
- Keeping the end loops parallel with the sidewall allows the zipties to keep the loops from digging into the sidewalls.
- And not cinching the zipties so tight they deflected the sidewalls.
I have over 20 miles on these with hardly any marks on the tires. I had about 40 miles on the first attempt. I also went from 16 to 8 chains on each tire (start one spoke away from valve stem, then after every fourth spoke). Though occassional slippage, increased traction is still sufficient so far.
