Snow chains for your tire size

Chains and snow socks are sold by tire size, and each one fits only a range of sizes. Set your size to see the chains listed on eBay that name it.

What to check before you buy

Your owner's manual says whether chains are allowed on your car, and which kind: some cars only take low-profile chains or snow socks.
Buy for the size on your tires, not for the car: winter tires can be a different size.
Practice putting them on at home, before the first storm.
Some states and mountain roads require chains or traction devices in winter: check before you go.
