Rear tires are down to the wear bars and front two are separated after 11000 miles with 5000 rotation. Alignment has been checked withno problems found and air pressure was kept at level indicated on car door. Tire shop can't find any problems or reason for tires failing at this point. I am a stay at home mom that rarely drives out of town and I do not drive aggressively especially with my son in the car. I would stay clear of these tires at all cost!
