No we did not have a problem. When checking the tires before going to the rally in May we noticed the 2 potential problems. The tires only had about 12000 miles on them. J P Morgan gave us the contact information. Contacted them and they gave us a claim number and picked them up on June 20, 2007. I started calling them weekly on Aug 31 and finally received the check on Nov. 26. It was a hassle but worth it in the long run.
