We have a 2002 MB EX. My wife was driving it today and hit a pot hole in the road. The hole cut the tire and ruined it. Come to find out there is not road hazard coverage on the tires(michelin symetries). We had to buy a new tire, cost $111.00. I couldn't believe that the tire didn't have road hazard, but in the tire warranty book it says under "what is not covered" road hazard is not covered. I am still in a little disbelief. I would have thought that they would have road hazard protection.
