Pair of zig-zag snow chains QV339 Volt Passenger. Perfect for a trip to the mountains. Tire sizes shown in picture and here: https://qualitychaincorp.com/qv339-volt-passenger/
Original price: $129.34
Rubber band not included ($10 to $15 https://qualitychaincorp.com/qv1174---replacement-volt-cable-chain-adjuster/).
Zig-zag chains are sometimes required (and ladder-type chains forbidden) in heavily snowy conditions.
Selling because I bought a new car with a different tire size.
