Question

Are there any limitations on fuel or tires in the Indy 500?

Answer 1

I know, from a couple years back, that there is a limitation on fuel and on the miles that Honda allows you to put on an engine. I'm not sure that there is a limitation on the tires though.

Answer 2

The only limitations I know of are,

19 gal of fuel at a time,

and Indy/track approved tires

as many as you can afford?

Answer 3

You must use Firestone Tires, there is no limit during the race, but there are limits during practice, testing, and qualifying.

Honda has mileage limits on their engine leases.

They must use 100% fuel grade ethanol, but again, I don't think there's a limit to the total amount they use, but they obviously can only put as much as will fit in the tank.

Answer 4

no limit on tires

and each team is alloted so much fuel for the month while at INDY
