Spare Tire problems of the 2006 Ford F-150

Husbands truck began wobbling noticeably while driving. Checked tires and came to the conclusion that 3 tires had bubbles in the sidewalls, and of the 3 tires 1 had a bubble the size and shape of a football in the middle of tread, I believe they were goodyear tires 255/65/17. Also, the wire inside of the tire could be seen on another part of the tread, which there wasn't much of. 27,000 miles on vehicle, bought used less than 1mo ago. Put spare tire on the worst one, took back to dealership and Ford replaced all 4 tires since the other one was different make and wrong size. Could have been serious accident involving tires if traveled 1,000 miles with family when attended grandmothers funeral.

On August 26, 2007 I was traveling east on highway 190 between kempner, TX and copperas cove, TX at about 10:30 a. M. In a 2006 Ford F-150 super crew with about 25,000 miles on it. Road conditions were dry and the roadway was recently redone. My speed was about 65 mph in a 70 zone. For no reasons that I can determine the right rear tire rapidly deflated. I managed to keep the vehicle under control and pulled onto the shoulder. The tire was destroyed with evident damage to the outer sidewall. I put the spare tire on and continued. Monday, 27 August I visited automax Ford and asked them to replace all the tires on the vehicle. The service manager told me that tire defects were the responsibility of the manufacturer. I made the decision at that time to replace all the tires with another brand.
