Purified nitrogen has been used to inflate tyres on aircraft and racing cars for many years but does it really make sense for ordinary car tyres? The air we breathe, and the compressed air normally used to inflate tyres, is mostly nitrogen anyway – 78% Nitrogen, 21% Oxygen and 1% other gases.

What are race tires filled with?
NASCAR Image Gallery High-speed cars need special tires for better handling and safety. 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.
Do race cars use helium in tires?
A lot of racing cars use a similar gas (I'm not sure what though) to helium, although it is lighter then air, the main reason they use it is because the tire pressure doesn't change with temperature.
What are F1 car tyres filled with?
The total manufacturing process for each tyre takes approximately five hours. F1 tyres are filled with nitrogen as it is more stable than air and behaves predictably even when the temperature varies.
Do race cars use nitrogen in tires?
Nitrogen in highly specialized tire service applications
Dry nitrogen mitigates tire pressure variations, so nitrogen-filled tires are also used in professional race car driving, where even the smallest changes in pressure can impact ultra-high-performance vehicle handling at extreme speeds.
Do race cars use liquid nitrogen?
Racers don't use nitrogen they use Nitrous oxide (N2O). Gasoline Burns in oxygen. Air has a fair amount of oxygen, Nitrogen in air actually slows combustion down.
Is it OK to mix nitrogen and air in tires?
It's never a good idea to drive on an under-inflated tire. Using compressed air in tires that have previously been filled with nitrogen will not harm your tires. While mixing the two won't result in an adverse chemical reaction, it will dilute the purity of the nitrogen and lessen its effectiveness.
Why is nitrogen used in aircraft tires?
Aircraft tires indeed are filled with nitrogen to mitigate temperature fluctuations, but not because nitrogen has any special heat-absorbing qualities. ... When tires get very hot, oxygen, the second most abundant component of air, can react with volatile chemicals in the rubber and cause an explosion.
How long do nitrogen tires last?
On average, tires filled with air lose about 1.5 psi every month, whereas tires filled with nitrogen will lose that amount in about 3-4 months. You will likely have to top off your nitrogen filled tires less often than if they were filled with air.
Is nitrogen lighter than air?
Nitrogen gas is only slightly lighter than air and readily mixes with air at room temperature. Cold vapors are more dense and will settle. Liquid nitrogen, a cryogenic liquid, has a very low boil- ing point of –320°F.
Are F1 tyres filled with nitrogen?
Another interesting point is that most of the F1 teams use dry nitrogen gas to inflate their tyres instead of air. ... Oxygen gas is far more reactive than nitrogen and at the high operating temperatures of F1 tyres (> 100°C) the oxygen reacts with the tyre, reducing the total pressure inside.
What psi are F1 tyres?
The minimum starting pressure for rear tyres for the race has been adjusted. On Monday Pirelli specified a minimum of 19.5psi for this race, which has been raised to 21.5psi. The minimum pressure for front tyres remains at 21psi.
Are F1 tyres sticky?
“The reason why we introduced this technology is that especially the Hypersoft last year, and C4/5 [softest 2019 compounds] are very sticky and, when you vulcanise and cook the tyre, it's difficult for the mould sometimes.
Why is nitrogen better than air in tires?
Since nitrogen molecules are bigger than normal air molecules, it is harder for them to leak out. This means a tire filled with nitrogen will maintain air pressure longer. Therefore, they say, you'll roll on tires that are always properly inflated, resulting in better fuel economy and longer tire life.
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.
