I was driving on the 495 out of the lincoln tunnel and my left front tire went flat. i did not hit any potholes. two days later driving on river road in edgewater nj i hit a small pothole, it was dark and torrential downpours, my tire immediately went flat. we pulled into a indoor garage, changed the tire, went to back out of the parking spot and the back tire went flat. i do not feel safe with these tires. they are continental - conti pro contact. *tr
