See the warning about using tire chains only on the front and the strong oversteer it can cause. Buy the right sized chains for your tires, links can be added or cut off but it is better not to have to. They tend to be a bit smoother and have more traction. Since there is always a couple crosschains under the tires, double filled chains do offer superior braking even if the brakes are locked up. Off season the best plan is to clean and oil your chains and hang them where they will be untangled, dry and available for the next winter.
Tire chains are always heavy and dirty.
You don't want them getting all tangled up and you don't want them sitting in a puddle of salty water to rust, they always get put away wet. The sealed ammo can that I used in my car is not really satisfactory. Even when sprayed with Rust-Stop the chains still rust inside it. Any comments on below ideas, or new ones are appreciated. Tie each roll with a strap or piece of rope.
