Nitrogen is the gas of choice for tires. Nitrogen has about 5 parts per million (ppm) of water where as compressed air has about 500 ppm. This allows for a more predictable tire pressure change during a heat cycle.

∙ 10y agoin England its nitrogen. and I think in formula 1 as well.
Nitrogen.
Nitrogen. Its expansion and heating rate is much lower than plain air.
air traditionally. but they are now filled with nitrogen
nitrogen

∙ 15y agoThat depends on the type of race you're talking about; nascar, dragcar, an Indy, off road, etc....... But for the most part, they all have one thing in commen, a high octane. Higher octane means, burns fast, better, and is better for you car. (the only racing car they might not use high octane fuel with might be off road racing, but I'm not sure)

They use 100% nitrogen because it doesn't expand and contract as much as normal air mixture.
nitrogen.

∙ 15y agonitrogen the answer is nitrogen thank you for getting the answer from wiki

∙ 14y agoNormally air that you can get out of a regular pump and ive know formula 1 cars to be nitrogen in their tires

A pit crew is a group of people there to fix a racers car when something goes wrong. They also fill the car up with gas, change tires and make adjustments during the race.
Nitrogen
Nitrogen, because it is an inert gas.
Most pro racing teams are using pure Nitrogen gas in their tires. This has the main advantage of minimising pressure changes as the tire warms up. It will also not feed a fire in a post crash fire.
No. A car will get better mileage with the correct tire pressure.
nitrogen
Nitrogen and oxygen = Air
Nitrogen is used because it has less parts per million of water than compressed air. It gives a more predictable pressure increase over a given tire temp.
a engine and if you have gas (and not a flat tire d;=D)
maybe the rubber in the tire expands more than the gas in the tire...but I don't really know.
A tire can effect your gas mileage by a lot. If you do not have a inflated tire you can get 2-3 mpg less than use usually get.
low gas, flat tire, broken gas
