Summary: Great snow performance... However,tread life expectation is never what any tire manufacturer claims it will be. My second set of CSTs and will put them on my wife's new Equinox when the need arises.
Summary: Change oil at 3,200 to 3,500 miles/ 5Qt. system. Most times I rotate tires every other oil change _ some times after the third oil change. I monitor air pressure with a quality gauge and use recommended pressure as posted in door frame.
Summary: Bought all 4 tires 3 months ago with front end alignment.. started out great nice and quite..put less than 5k on them...experience bad vibration both in steering wheel and seat had them re balanced and still bad vibrations. The tire place I bought them from is replacing them..
Summary: Worst tires I have ever had. Saw the 70000 mile warranty and thought it would be a good purchase even though they were expensive. Turned out they were worse than the cheaper brands I usually buy. In 2 years (less than 30000 miles) I have had 3 punctures, and 2 replacements.
