A few years ago I learned that Discount Tire not only does "FREE" tire rotation, but you can also purchase the Road Hazard Warranty on your new factory tires. It gives you free tire repair and maybe even a replacement. Our first rotation was in the Jacksonville, FL Discount Tire store while across the country from San Diego, CA. A few weeks later after another trip to WY we got them rotated again here in San Diego. One more San Diego rotation during the winter. Our next rotation will probably be here in San Diego just before we leave on our next cross-country trip in June.
