37,000 miles and you want a warranty claim? HA HA- Never heard of such thing. Most car tires are showing signs of being a tad tired by 40K to start with. I have 40K on ours and we are at the wear bars - new tires next month! WE are not getting the Continentals again! They have had major issues holding balance and at least one tire has gone out of round. The replacement tire will be a BFG Touring tire which has some great reviews from several different vehicle owners and the price is a good value. I can't wait to get rid of these lousy Continentals.
