I have two sets of Radial Chains.
These slide over your radial tires for use in snow/ice.
When I was in HS/college, my dad had me keep these in my car during the winter.
One set fits 195/60/15 tires, the other 205/55/16. Actually they both fit many different sizes which are listed on the side of the box for each.
These are FREE (you pay shipping if you can't pick them up) to anyone who wants them. I no longer have a use for them as my TMs are retired from facing the horrors of winter
