i wont debate the fact that firestone had a part in it because it was proved that a part of the tire was left out.My point is that its not all the tires problem it was fords as well,would the tires held up if the pressures were 35psi and not 28psi?Allof the wreck's happened AT hwy speed not rollin through town.I know there was plenty on aired up firestones that came into the shop that got replaced.
