Compressed air which is normally used to inflate car tyres is a mixture of 78% Nitrogen, 21% Oxygen, 1% water vapour and other gases. Oxygen reacts very easily and when introduced into the tyres through compressed air penetrates the tyre walls and causes under inflation.

Why is a gas used to fill the tires?
Air, the standard gas used to fill car tires, is comprised of 78 percent nitrogen. ... Like all gases, air expands when heated and contracts when cooled, and tire pressure will rise or fall accordingly. Nitrogen has a slight edge over air, in terms of tire pressure, because it's less susceptible to temperature changes.
What gas is used for tires?
Using Nitrogen in Tires
In its pure form, nitrogen has been used primarily because it doesn't support moisture or combustion. Nitrogen is an inert (non-flammable) gas – basically, nothing more than dry air with oxygen removed. In fact, ambient air contains about 78% nitrogen, 21% oxygen and 1% miscellaneous gas.
Why are tires filled with air?
Rubber. When it comes to tire design, the most important factor is the ability of air to be compressed and adjust its volume with ease, unlike something made of a solid material. ... This is why rubber tires were able to be used in the past, before high speed automobiles were on the roads.
Why do they put helium in car tires?
It makes intuitive sense: fill your tires with helium instead of air and you'll save a few ounces of precious weight. ... Balloons filled with helium are lighter than air, so won't filling tires with helium save weight? Not exactly. Helium is a very low density gas; far less dense than the Earth's atmosphere.
Why do race cars use nitrogen in tires?
See more NASCAR pictures. Many race car teams use nitrogen instead of air in their tires because nitrogen has a much more consistent rate of expansion and contraction compared to the usual air. Often, a half pound of pressure will radically affect traction and handling.
How do car tires hold air?
The inner liner (in the center of the tire diagram) is a rubber compound bonded to the inside of the cord body that retains air under pressure. ... A tire's beads, bead filler, and inner liner work together to hold air within the tire walls.
What kind of air goes in tires?
Traditionally, car tires have been filled with compressed air. Air is 78 percent nitrogen and just under 21 percent oxygen, and the rest is water vapor, CO2, and small concentrations of noble gases such as neon and argon.
Which is better air or nitrogen in tires?
Nitrogen molecules are larger and slower moving than those of compressed air. Because of this, nitrogen won't seep out of your tires as quickly as air will, helping to maintain proper pressure for a longer period of time. ... Under/over-inflated tires are more difficult to handle, and increase your risk of a tire blowout.
Why does a tire get inflated with air rather than a liquid or solid?
1. Cushion: Air is much, much better in absorbing shocks then solids. 2. Resistance: Rubber tyres filled with air offers lower rolling resistance in comparison to Solid tyres.
Why do they put hydrogen in tires?
The main benefit of nitrogen-filled tires is that the loss of tire pressure is slower, because the gas in the tire escapes more slowly than air does. With more stable tire pressure, the thinking goes, you'll get better gas mileage and get full tire life since you're always rolling on fully inflated tires.
Is nitrogen filled tires a gimmick?
Paying to fill your tyres with nitrogen is a scam. ... That's 50 million tyres. They're wearing out every four years - let's say - and most tyre retailers are busily dry-humping your leg to get you to spend - $10 per corner - to pump up with a miraculous gas: pure nitrogen. It's potentially a $100 million consumer scam.
What does a green cap on a tire mean?
Some cars are even sold with the telltale green caps on valve stems, signaling the tires have already been filled with nitrogen. Dealerships and tire shops often charge owners to fill tires with nitrogen, at $5 or more per tire, during routine service visits or when replacing tires.
Does premium air for tires exist?
Generally speaking, tire installation centers will charge a premium to inflate your tires with nitrogen instead of regular air. ... Additionally, nitrogen is not available at all tire locations, so for the sake of convenience, using regular air is the big winner.
Do nitrogen filled tires lose pressure in the cold?
Even though nitrogen is not as “reactive” as regular compressed air, you can still expect to lose about 2 percent pressure for every 10 degrees F in temperature reduction. ... great for your customers AND your technicians as nitrogen filled tires, wheels and related hardware are always dry, and rust and corrosion free.
Why do F1 cars use nitrogen?
Formula one tyres are not like road tyres, F1 tyres are filled with nitrogen instead of air. ... The primary reason why nitrogen is filled in Formula one tyres is because of its higher consistency. The moisture content present in air is variable as it depends on the local weather conditions.
