Sold the 4runner, so I'm unloading these also. This is a pair of low profile snow cables that fit the stock 265/70/16 tires. We carried these with us when traveling the local mountains in winter, but they have never been used. Here they are at amazon:
Amazon.com: Security Chain Company Super Z6, SZ441, Cable Chain for Pickups & SUVs - Set of 2: Automotive
$50 and you can pick them up if you're local (Orange County CA) or pay to have them shipped, they weigh around 10-15 pounds.
