Some of us remember when Hoosier came to Winston Cup back in the day.
They were fast, very fast.
But...
Hoosier did not have the ablity to produce enough tires to supply all the teams at any given event. NASCAR, in fairness to all, made it a requirement that any supplier would have to bring an inventory of tires large enough to supply all of the teams and Hoosier decided to withdraw instead of making the commitment to supply tires to Winston Cup.
(Oopps, I guess that should be NEXTEL Cup!)
The only two tire companies that I can see large enough to make such a commitment today might be either Michelin or Firestone/Bridgestone. I don't believe that either Hoosier of American (McCeary) have the production or financial ablity to make the necessary commitment.
