All of the tires used up during racing of cars where are they disposed of How long do the tires last during a race such as the Indy 500 or 24 hours of Daytona. Thanks?
I believe they go back to the manufacture for recycling, the longevity of tires depends on: track conditions and surface, how the car is set up, and how soft or hard the tire is, (a soft tire will wear-out much quicker than a hard tire).
Two things racecar tires have to worry about with that your family car tire does not. \n \n1. Heat dissipation and rubber melting rate, racecars want the rubber to melt a little, but not too much. \n \n2. Stiffness, they want very soft rubber, but they don't want it to deform under acceleration, t…urning and braking so a way to prevent it is increasing the width. \n \n \nRace car tires are much wider â up to 12 inches wide in the front and 16 inches wide in the rear, whereas the typical passenger car tire is seven to nine inches wide. \n \nThe reason they are wide is to increase stiffness so that during acceleration, turns and braking, the amount of rubber touching the road does not decrease too much. \n \nRacecar tires use rubber that is much softer than rubber on cars. It is more like a soft rubber eraser than anything else, and very unlike the hard rubber found in passenger car tires. Since they use very soft rubber it tends to melt during the race, which makes the rubber even stickier than before. \n \nContrary to intuition, the large width of a racecar tire does not increase the frictional force available to it by itself. If you take your own car and put in tires that are 3 feet wide made of the same kind of rubber, you will not get better grip onto the road. \n \nThe reason for this is because as you increase the surface area of the tire, the weight pushing down on a rubber particle decreases. At the macroscopic level, as you increase the surface area touching the ground, the rubber/glue particles break contact with the road and hover over the road instead of touching because there is less force pushing on every rubber particle. \n \nSo ultimately the amount of rubber molecules making contact with the road particles are not increased when you use a larger or wider tire on a vehicle with the same weight. \n \nMost race cars have slicks that is a tyre with no tread for maximum grip in the dry. then there is a medium tyre which has a little tread for damp conditions, and there is a tyre called wets which have a lot of tread for raining conditions\n \n\n\n\n\n\n ( Full Answer )
nitrogen. They use 100% nitrogen because it doesn't expand and contract as much as normal air mixture. . nitrogen. Nitrogen.
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.
nitrogeon is used to inflate race car tyres due to the consistenttyre pressure throughout different tempertures.
NASCARÂ© Winston Cup TRUE TIRE HISTORY Wheel and Tire Characteristics: The 15" wheel rim is made of steel, fixed to the hub by five nuts (imposed by NASCAR). Formula 1 wheels use a single nut and four tire changers (two in NASCAR), which largely explains the difference in the pit stop durati…ons below 10 seconds in F1 (formula one) versus 16 to 20 in NASCAR. Lightweight metal rims are also available on the market. The dimensions of the tires are usually 28 x 12 x 15", being the diameter, width, and wheel rim diameter. In standard tire description, this corresponds to 300/54 R15, which is an ultra-low profile: height/width = 54%. They are inflated with nitrogen, which is much more stable with temperature than compressed air. This allows the pressure to remain almost constant over a large temperature range. The tires are inflated around 50 psi. and teams adjust this pressure to improve the grip of the tire or to equilibrate the inside, center and outside tire temperature. Click Wheel for More Information About Sidewall Description Details: In the early days of NASCAR , the tire changers were using the good old cross to screw and unscrew the nuts. Today, pneumatic air guns have replaced it, but NASCAR allows only 2 air guns per team during the pit stops. However, the five nuts are still there and most teams glue them to the rim prior to the race to gain a few seconds. When the new wheel is placed, the air gun torque breaks the glue and the nut is tightened normally. Numerous tire changers keep spare nuts on a ring attached to their belt or even in their mouth! During the pit stops, the right tires are changed first for a simple safety reason: to have the right side cleared when the car restarts. If a wheel gets out of control of the crew and rolls into the pit road, the team gets a penalty. This happened during edition 99 of Daytona 500 when a wheel escaped its tire changer and kept rolling for more than 150 ft. on the pit road. The outgoing cars had to swivel around it to avoid a collision; some of them even went through the grass. Being a tire changer is not an easy job: each wheel weights more than 50 pounds and the incoming tires are hot, very hot... The average temperature for a race car tire is 200Â°F. Nevertheless, each wheel is exchanged in about 7 seconds!!! Tires which are new from factory are called "stickers" because they still wear the manufacturer ... sticker; after a few laps, some tires are put aside for the race so the driver does not restart with unverified tires. These tires are called "scuff". Bias ply tires also have their advantages: they allow the team to introduce some "stagger", by under inflating the left tires and over inflating the right ones. Since bias ply tires expand in diameter with pressure, a stagger is introduced. It is the difference between the diameter of the left (smaller) and right (larger) wheels. Stagger improves the car capability to turn left, but also increases tire temperature and wear-out in the straight-aways. For this reason, this method is mostly used on short tracks, where 0.5 to 1" stagger is not uncommon. Radial tires have somewhat perturb Ted this practice, because they expand laterally with pressure. Stagger can only be introduced by using tires of different diameters. History: When NASCAR is born in 1947 , the race tire market is solely dominated by the Firestone Tire Company. NASCAR's emerging popularity in 1954 gets noticed by Goodyear and they re-enter the competition by using police car tires at the now 4-year old Darlington speedway, and finally defeats Firestone five years later establishing a new speed record with Jim Reed at this same track. 1966 is a milestone year for the racing tire industry when Firestone and Goodyear started manufacturing the "Inner Liner Safety Spare", called Lifeguard for NASCAR racing. This tire is in fact a second envelope inside the tire, which prevents instantaneous deflating and allows the driver to return to his pit after a flat. From now on, all NASCAR are be equipped with the Lifeguard. The two tire giants will alternate victories and speed records when Firestone stops producing racing tires in 1974. Goodyear remains the sole supplier until 1987, when a company from Indiana, Hoosier, starts supplying racing tires, first in the NASCAR Busch Grand National series, then in Winston Cup racing, where Hoosier wins several races. It is interesting to notice that all tires manufactured so far are bias-ply type, when in Europe Michelin had long ago invented and patented the radial tire. The story doesn't tell if Michelin's patent expired, was bought or turned around, but in 1990, Goodyear proposes the Eagle radial race tire which immediately proves considerably superior to the now obsolete bias-ply tire. This puts a temporary end to Hoosier's contribution in NASCAR Winston Cup. The following years see new generations of tires and improvements of the inner liner. Hoosier tries returning to Winston Cup but succeeds to win only 3 races during the 1994 season and withdraws from Winston Cup and Busch Grand National, to concentrate on the smaller series, such as Winston West and Featherlite. Today, Goodyear's yellow-lettered EAGLE tire is the only one used in NASCAR. Tire History Tire History Reading Tire Sidewalls ( Full Answer )
Nitrogeon is used in race car tyres due to nitrogeon particleseliminate moistures and tyre pressure variation depending on thetemperture. This gives the driver better control of the car.
Nitrogen is used because it has less parts per million of waterthan compressed air. It gives a more predictable pressure increaseover a given tire temp.
They do not. I think only Formula 1 does to protect the crowd. They go well over 200mph. When Bill Elliott first went over 200 at Talladega back when, NASCAR's answer was the restrictor plate, used to slow the cars down.
There's moisture in air. When you fill your tires with compressed air, the moisture goes in the tire too. Moisture then has potential to rust out the rim from the inside. They use other gas (nitrogen?) that doesn't have moisture. Usually garages will put green air valve caps on tires filled with gas…. ( Full Answer )
usually, racing slicks made by Goodyear or Firestone, if its a wet track rain tires.
in 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
The normal racing tyres are slick and have no tread. The intermediate tyre has a 2.5mm tread, and the full wet has a 5mm tread.
That 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 fue…l with might be off road racing, but I'm not sure) ( Full Answer )
So that they can drive faster in races. That is the basic answer, but its so they can stop later, turn faster, and stick to the road. More rubber means more grip, and more grip means going faster.
it depends on the type of racing, weather, driver, and the track. id have to say anywhere from 1- mabey 20 sets max.
No, reason: trailor tires are made so that the side walls can take the strain of "road sway" while pulling a trailor. if you've ever followed someone towing a trailor you might have seen it swaying back and forth from time to time. car tires are not designed for that kind of stress.
It depends on a bunch of things, new or used, and what type of racing tire(drag, road race,NASCAR) I live in North Carolina, I get them free, or cheap. I have them lining my driveway and they are full of rocks. you can get a hot lap tire that has had maybe 30 laps on it and still plenty of tread for… like 20 bucks put here if not free.

Normally air that you can get out of a regular pump and ive know formula 1 cars to be nitrogen in their tires
rubber Rubber is used with many other things to make different tires, depending on what they will do, once on a car.
I think it is Nitrogen. The normal air mixture pumped into regular road cars is not efficient at high speeds and will lose pressure easily. If that happens there could be catastrophic consequence at high speed. That is why they use nitrogen If you pump nitrogen into the tires of your regular road… car, you need not check tire pressure for 3 months. ( Full Answer )
Nitrogen would be the word you are looking for. its because the expand and the heat ratio of the nitrogen is lower then air. very good question
All Nascar teams will over the coarse of the weekend with practice and racing will typically use about a thousand tires.
If the mass of the racing car is low , it is able to move faster; and if the racing car has wheels wide apart , the mass is spread on a large area and can travel faster and cover a bigger area at one time.
low presher you get more tractshun and make your car go slower and with high tire presher you get less tractshun and more speed glade to help =]
The more rubber on the ground = more traction or grip for the cars e.g. more speed.
nitrogen has significantly less moisture than compressed air. By eliminating as much of the moisture as possible you have a much more stable and predictable air pressure increase as the tire heats up.
An argument can be made that Firestone has the bets racecar tires, as Firestone tires have not been subject to controversies that have befallen Goodyear in the last ten seasons.
There are many kinds of tires because there are many kinds of race cars and conditions. Nascar (Cup, Nationwide, Trucks) use Goodyear slicks that have many different compounds for different tracks and differing temperatures. One compound is used by all competitors which allegedly puts everyone on an… equal footing, although some teams are more equal than others. Drag racing vehicles (dragsters and funny cars) use big "wrinkle wall"slicks in the rear and skinny tires up front. Other classes are required to use street tires or "DOT slicks" which are street legal tires that come very close to slicks but still retain some sort of tread pattern. Formula One cars use slicks for dry condition and grooved "rain tires" for (obviously) rainy conditions. This holds true for the "upper division" series like Indy cars, Le Mans and American Le Mans series as well as Grand Am in the States and touring car series in other parts of the world. Dirt track cars use rear tires that are generally a blend of slicks and rain tires. They're generally very soft and wear quickly. Land Speed Racing vehicles (Bonneville Salt Flats) use skinny tires to reduce rolling and wind resistance. Many classes use front tires made for dragsters. Other high speed classes use specially-constructed tires to withstand the forces applied to them at speeds over 300 mph (480 kph.) Brands and manufacturers vary widely from one series to another. Goodyear, Firestone, Hankook, McCreary, Hoosier, Dunlop, Michelin and more make race tires, some of which are mandatory in a class and some series allow tire brand competition. ( Full Answer )

Because humans do not have the ability to brake and release sufficiently fast enough to stop and not skid. ABS removes this problem. Just stomp on the brake and let the electronics worry about how to do it.
My new Chevy Equinox came from the dealer with helium filled tires. Since this cost money,what happens on a trip if they leak and I need to add air?
Classical surface friction is independent of contact surface area yet automobiles still benefit from broader tires because of supplementary forces involved. Because the tire is deformed under loads, it cradles every imperfection in the road surface. The greater the surface area, the greater the numb…er of imperfections that can be cradled therefore increasing the maximum lateral and longitudinal force available. The more force that the tire can exert on the race car, the faster it can turn/accelerate/brake. This ultimately reduces lap times and improves the chance of beating your competitor. ( Full Answer )
Not normally. Most stations use just plain ordinary air. Some places are starting to use nitrogen in the tires. those places that do use nitrogen, do so as to reduce loss of pressure over a much longer time-period, as supposedly, the molecules are 'bigger-fatter' than those in regular 'air' /s…o I've heard/--and 'those places' sometimes replace the valve-stem-caps with bright green-ones as a visual tip-off, although who knows if that nitrogen was replaced /for some reason/ by yet another place, months later. one would hope they change the cap to black again, if so air only was used to re-inflate. .

They are wide to gain maximum traction and bald because they are only used on dry tracks. In wet weather, racing tires with treads are used.
Not at all, even if the vehicle was once used for any type of profesional racing does not make it a race car. Just because a car is fast does not make it a race car either. Even if the car is currently used for street racing, it is not legally a race car. Everybody wants to call their car a race car…, but if you don't professionally race it then don't bother saying that it is a race car. ( Full Answer )
Yes. That is why space saver spares are made from a different compound of rubber to normal tyres. A space saver should have a ten year life.
There are different types of tires depending on what kind of racing they're doing. But pretty much all racing tires tries to be grippier than regular tires. This usually means that they wear out faster, and create more road noise than regular tires, which no one really cares about if can win them th…e race. ( Full Answer )
Natural Rubber is like chewing gum. To make a stable usable product you mix in sulphur and heat the mixture up. This is called Vulcanization. This is how tires, Bouncy balls, etc were made until the second world war. Since then the process is similar but the ingredients have change to give us synt…hetic rubber. ( Full Answer )
Traction and grip The more rubber of the tyre touching the ground the more the tyre will grip the road. However, in wet or poor conditions a "wet" tyre will be put on. which has grooves to help expel the water.
Nitrogen is pumped into tires as it is believed that it is more stable than air giving it better traction with less wobbling.
softer the compund of the tire, the more grip it has, down side is they don't last long, top fuel dragster tires last only 1.25 miles
Mostly specialist tires made by relatively small manufacturers. I see many Mickey Thompson, Hoosier, Hankook and Goodyear Eagle tires at drag meets.
Car tires cover the wheel rim. They are made of rubber with grooves to provide traction and act as a cushion to absorb the shock from large bumps or jolts.
Typically a jack and a tire lug wrench. You can also use a ratchet or impact wrench.
A burn out will ruin tires on race cars by burning up the rubber. The rubber of the tires will get worn from the friction of the pavement causing the tires to tear.
if there is no grooves on racing cars tyres then the cam attempt toan accident while drifting 1.car can move out of track as it takes turn at speed of more then60 km ph 2.car can take air trams(take flips in the air) 3.reduce sprrd and bad starting
Many transfer stations will take old car tires but there may be a small fee per tire in some places. Call your local transfer station.
Notice that they are also very low to the ground. All of this helps them stay on the ground.
