You still don't understand it was only ever a joke!?
I know the two different vehicles but it's you who repeatedly mispell Econoline. The E in E-250 stands for Econoline.
Are you arguing some position here, that you're correct or do you seriously not understand it's a joke.
Also are you sure it was Michelin? did they own Firestone, I don't think so. They were and are owned by Bridgestone of Japan. But do try educate me on the models and all these other things. You know Firestone had been a Ford supplier since about the beginning of the Ford brand and as I recall parted ways after the exploding issue.
