Built my own Snow Chains for my 35s. Used mainly Harbor Freight parts and the total cost was around $70. Great piece of mind, and saves me from the $1000 California "must have" snow chains law.
HF-2 buckets of 1/4" x 35' chain
HF-1 box of 21" rubber bungees (not pictured, but for tension)
HF-2 bags of twist lock chain connectors (3 per bag)
A vise and bar to open links (Easy) or two screwdrivers (hard!)
You have to measure your actual tire height, and subtract 4 inches (as chain runners should be on sidewall, not on tire tread), then multiple by pi (mmmmm Pie) to get the circumference. Then, measure across tire, mine are 12.5", and add two inches. Then, measure the actual length of the chains to use/cut (I think mine were 97" x 4 runners and 14.5" x 16 for links, 8 on each snow chain). You will cut the runners, and have to cut links to connect them together like a ladder. Then, use a vise, or screwdrivers to reclose links. Measure/fit on tire, if good to go, weld and you are done! Was a fun project. There are some Youtube Videos that help to review also.
