My fourth set of Continentals and insist on them when buying replacement tires. The OE tire that was on this car wore well although ruff ride and slick when worn and age hardened to the replacement point. Replaced at Tirerack SB in a snow storm and didn't think I could even pull into the service area, the OE tire had no grip at all. Going home was the reverse, grip, ride, and sure footeness was back and the car handled and rode great. Tirerack service was equally as great as always. Sorry, can't rate them for sand, mud, and rock, why would I drive there?
