RE: Continental Pro Contact GX SSR MOE 245/40 R19 98 H M+S Original factory installed Mercedes E450 tires. I had 3 blowouts from hitting small potholes on 3 different tires in 1.5 years. These are complete immediate blowout going completely flat on impact. It could have very dangerous if I were driving a little faster and fortunately there was no other damage to the car or other persons. In each case, I hit a small pothole, and the tire blew out, flat to the ground. Because these are run flat tires, on the first 2 incidents I was able to drive home and to the dealer for tire repair/replacement. The third one was so bad that I could not drive all the way home and had to get towed. But all 3…
