Car in pit lane prior to start. Look close and you will see it has Firestone tires and appears to have silver and not gold rims
It would make sense for the colors of the wheels to be different. It would make it much easier for the guys in the pits to get the right tires on the right car.
Ironic to think that if McLaren and Shelby had honored the sponsorship with Firestone, this car would have never won the race.
