Every few years there is a defective tire scandal involving Firestone. I remember Firestone 500 tires splitting up the middle in the sixties, Firestone 721, tread separation flying to pieces, Ford Explorer (Exploder) Firestone wrecks etc. I wouldn't own Firestone tires if you gave them to me for nothing. I might ride in a Firestone equipped car on a $1000 bet. If it was no more than 10 miles at 30 MPH.
