80%nitrogen 20% oxygen........ which is the exact same gas as ambient air. you put AIR IN 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.
No. A car will get better mileage with the correct tire pressure.
Rims are wheels. Your tire goes on them.
A tire
(Improving my own awnser) The basic formation of a pit crew goes like this: Gas-man goes on the left side of the car (right side at Walkins-Glen) to put gas in the fuel cell Rear/front tire carriers carry the tires on thier respective ends of the car for the tire changers can switch the old tires out of the new "sticker" tires (named for the fact that teams leave the tire information stickers on the tire), while the jack-man rolls the jack into a slot underneath the car where there is a little pipe where the jack catches so the car can get lifted on that side.
a engine and if you have gas (and not a flat tire d;=D)
For all kinds of things. Better gas mileage, better tire life, so your car goes straight, so your wheel bearings last longer.
The city will come around and put a boot on your car for unpaid tickets. The boot goes around the tire to prevent the tire from turning.
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
i have both and my nitro gas goes faster than the gas
