duh, to keep the price lower...also what Tire Rack charges for retail would be no where near what Ford would pay wholesale if they bought thousands of them...they probably still have a contract with Goodyear for the GT500
I'd put my money on this more than anything. shelby american could have an agreement with goodyear and ford has to follow it to keep the agreement between them and shelby..they probably still have a contract with Goodyear for the GT500
