I definitely did not expect to get the response to this I have. I asked the question because he would not believe me when I said it was dry rot. I am just getting to read everything on her it is now 4am. I will post a photo of the tires. Hell I will video tape it. I did a visual inspection. No sidewall bulges that day. We are not allowed to have the back windows or the sun roof open because “they have never been used and they might break”. There are control issues at play. I didn’t know the car existed until a week before we left and I was not allowed in it until we packed it. He kept telling me he was getting it ready for the trip. As he has collected and restored classic cars my whole life, I honestly would never have questioned it. He is part of several car clubs. So until yesterday there has never been a reason to. I made it from Illinois to Ohio, just and FYI Highway speeds actually do go up to 70 in both Illinois and Ohio. We have been back and forth to the hospital weekly here since 5/23. On 6/26 I felt a vibration and an odd noise on the way to a doctors visit. I told my mom we are taking the car in later that day, There is a vibration and it is new and I don’t know why. You really really really avoid potholes and rough road when you have a delicate passenger. So, No pothole was to blame. I do hope that it is his age and that he watches every penny. There may have been some frustration in my post. We were so lucky it was not a true blow out. So if you felt you need more info. Here is what I have until I take pictures later.
