One problem related to tire bead has been reported for the 1999 Ford Expedition. The most recently reported issues are listed below.
I would like to forward a copy of the e-mail that I sent to firestone three weeks ago but I am unable to paste that letter into this box. If you could give me the appropriate e-mail address and whatever reference number would tie my letter to this form I'll send a copy. The short version is that the tire that my dealer installed on my truck to replace one that they had destroyed failed after 600 miles. There was a major deformation on the inside sidewall that pushed the bead away from the rim and allowed all the air out. I would have dismissed it as an isolated manufacturing defect but read the next day about the major problems associated with firestone tires and became more concerned - I wrote firestone and they seem to have decided that the best thing for them to do is to ignore me - (I do realize that they have their hands full now so maybe I'm somewhere on a very long list) - in any case I'm registering the problem with you folks. I'd be happy to forward a copy of the letter if you will let me know where to send it. ( dot number: unknown tire size: p255/70r16 ).
