Each time you go to a tyre shop or a gas station to top up the tyre pressure in your vehicle’s tyres, what the attendant fills into the tyre is normal compressed air. But what exactly does compressed air contain? Compressed air is made up of 78% nitrogen, about 20-21% oxygen, and the balance one percent consists of CO2, and tiny concentrations of gases such as neon, argon and water vapour.

 When you specifically fill nitrogen gas into the vehicle's tyres, then you should have 100% dry nitrogen in your tyre. Dry nitrogen denotes that no        moisture content or any other gases are present in the tyre.

 Jay Chakraborty, who recently bought a second hand car, says, “After I bought my car, I changed the tyres and I’ve heard so many people talk about  how good nitrogen has been for them that I decided to get my new tyres filled with nitrogen air. The car feels a lot better on bumpy roads, and I don’t  have to worry about checking tyre pressure every week.”

Benefits of nitrogen Vs compressed air

Nitrogen as a gas is made up of big molecules, whereas oxygen molecules are much smaller in size compared to nitrogen molecules. When compressed air is put into a vehicle’s tyres, the moisture in the tyre seeps through the rubber over time and evaporates quicker as its molecules are smaller in size. But as nitrogen molecules are bigger in size, they do not permeate the tyres rubber so easily and hence will stay in the tyre for a longer duration. This means that your vehicle’s tyres will lose less pressure over time compared to regular compressed air filled tyres.

For example: An inactive vehicle, whose tyres are filled with normal compressed air will lose tyre pressure every week. But a 100% nitrogen-filled tyre will lose tyre pressure a lot slower and won’t need to be topped up as frequently. 

Titus Remedios, “I filled nitrogen in the new tyres that  I purchased for my Maruti Ecco in June 2019. That time the tyre pressure filled with nitrogen was 35Psi. I use the car once a week and after the lockdown, the car hadn’t been used in months. I recently went back in October 2020 to the place where I had filled the nitrogen in the car tyres and the tyre pressure after 14 months had only dropped to 22Psi. .

Another point to note, nitrogen filled tyres get a green or blue colour valve cap. This is a universal symbol that your vehicle's tyres are filled with nitrogen and not compressed air.

Is Nitrogen right for you?

Over-inflation and under inflation of tyres make a major difference on the race track. But on your normal city road does it make a huge difference? Under-inflated tyres normally lead to less mileage, uneven wear on the tyre treads and more tyre wear and tear overall. Over inflated tyres run the risk of burning out the contact patch on the tyre too quickly, while adding more bounce vs grip to a vehicle's stability. In hot climate conditions, your vehicle's tyre pressure can jump up tremendously. Highway running speeds coupled with a harsh sun beating down, can lead to a  tear in the tyre or in extreme conditions, a tyre bursting. This is where nitrogen-filled tyres shine the most. Due to their molecular build, nitrogen molecules stay at a constant temperature in a tyre. So even if the temperature outside decreases or increases, the nirotgen in the tyre will remain the same. That is why race cars and racing motorcycles only use 100% nitrogen in their tyres all the time.

Now we are all not professional racers, but we do commute on a daily basis and even go for the occasional weekend drive out of the city for some sightseeing and relaxation. Will filling nitrogen in your vehicle's tyre help you? There are many who swear by nitrogen-filled tyres and an equal amount who feel that regular compressed air works just fine.

Personal tyre maintenance

If you are someone who keeps a check on the vehicles tyre pressure weekly and tops up the air when needed, you won’t need nitrogen filled into your vehicles tyre. However, if you are someone who tops air pressure once a month or once in two months, then filling nitrogen in your vehicle's tyres will help you reap the benefits of it. If you constantly make long highway trips and most of your time is spent behind the wheel, then filling nitrogen in your vehicle's tyres will be a boon.

Yash Ramrakhyani from Palghar runs a big tyre shop which sells Apollo, Bridgestone, Continental, Michelin and Yokohama tyres for every vehicle from a scooter to a heavy duty tempo. He says, “I get an average of 300 customers a year who want nitrogen filled in their vehicle’s tyres. There was a big local demand in the area for nitrogen-filled tyres, hence my father and me invested in the nitrogen unit. Tyres don't get hot, and nitrogen level doesn't go down so fast is what I have heard from customers as feedback, but the fact that people think nitrogen levels in the tyre doesn't go down is false. Even nitrogen-filled tyres have to be checked for tyre pressure once a month.

Nitrogen myths busted

Myth 1: Your vehicle's mileage will increase.

Truth: Your vehicle’s mileage depends on a lot of factors, tyres being just one small part of that equation. Having nitrogen filled tyres only gives you the benefit of having a most constant tyre pressure. However compressed air and nitrogen filled tyres both will loose pressure after a certain amount of time.

Myth 2: Your vehicle's comfort will be better, it will be soft on bumps.

Truth: Compressed air or nitrogen filled tyres will react the same way when on bumpy roads. It is the rubber compound and the type of tyres that you have that will make a difference in the ride or drive quality. As long as you maintain the right air pressure in your vehicle's tyres, you’ll be good.

Myth 3: You won’t have to fill up the tyre pressure as frequently.

Truth: Well this is true. Nitrogen-filled tyres will retain the pressure in your vehicle's tyre for a longer time duration compared to tyres filled with compressed air. However, even nitrogen-filled tyres loose pressure over time and you have to get the pressure checked and topped up from time to time.

Myth 4: Your vehicle's tyre will last longer

Truth: The tyre on your vehicle rely on you to make sure you maintain the recommended air pressure inorder for it to do its job properly. Under inflated and over inflated tyres will wear out faster when compared to tyres that have been properly maintained.

Myth 5: The rims on your vehicle won't rust

Truth: There is some amount of truth in this. As nitrogen-filled tyres contain less or no water vapour, the moisture content in the tyre is less. Less moisture equals to less rust on the inside of the wheel. But that doesn’t stop the rest of the wheel from rusting due to everyday washing and climate conditions.

Myth 6: There are few tyre shops / fuel pumps that offer nitrogen.

Truth: Compressed air is mostly nitrogen gas. So even if you have nitrogen-filled tyres, but you’re running low on tyre pressure and there’s no nitrogen filling station around, you can still fill normal compressed air. It will not have any major impact on your vehicle's tyres. Maintaining the right tyre pressure is key.

The catch

The nitrogen that you get filled in your vehicle's tyres is not a 100% or even 99% pure nitrogen. A brand new or even an old tyre once deflated has some amount of air inside it. It is the atmospheric air that's already there all around us. So unless you drain all the air in the tyre out and refill it nitrogen and drain the tyre again 2-3 times, you’ll still be running your vehicle's tyres with 90% nitrogen and not 100% nitrogen. But even then you’re not guaranteed that your vehicle's tyres will be filled with 100% pure nitrogen. There is no way to measure how much nitrogen is there in your vehicle’s tyre. Nitrogen will cost you, whereas compressed air is free at most petrol pumps or Rs.1-2 at a tyre shop. Nitrogen costs on the other hand vary from place to place and the kind of machine they have. The machines that are at the tyre shops or petrol pumps that offer nitrogen, do not deliver pure 100% nitrogen! Some machines will have a percentage rating of how much nitrogen it provides to the tyre and some have no percentage levels at all. Filling nitrogen in your vehicle's tyres can cost you anywhere from Rs.150 for four tyres to Rs.50 per tyre and can go all the way up to Rs.1,500 for a set of four tyres.

Conclusion

Have you ever noticed that vehicle manufactureres never recommend nitrogen in their manuals or at their service centers. The reason behind this is your vehicle's tyres are manufactured to run on normal compressed air. As long as you maintain the right tyre pressure in your vehicle’s tyre, you’ll be fine.

Pirelli prepares to take centre stage at its home race, the Formula 1 Pirelli Gran Premio d’Italia 2026, which marks the 77th edition of the historic event. The upcoming weekend at the Monza circuit is highly anticipated, driven by the fervent passion of the Italian tifosi and the venue’s deep-rooted legacy within motorsport. As the title sponsor, the Italian tyre manufacturer is set to celebrate its longstanding relationship with the Temple of Speed through a series of artistic and ceremonial initiatives.

The company’s bond with Monza transcends mere geographical proximity between its headquarters and the autodrome, being historically cemented by numerous victories on Pirelli rubber. A landmark triumph occurred on the circuit’s opening day in September 1922, when Pietro Bordino won the Grand Prix driving a Fiat 804. This year’s race will be commemorated with a unique trophy designed by the Italian artistic duo vedovamazzei, which will be presented to the top three finishers on Sunday, alongside special edition podium caps.

The trophy, named FRAGILE, is conceived as a layered composition of everyday household objects such as cups and bowls, stacked into a visually unsteady vertical form. The artists, Stella Scala and Simeone Crispino, drew inspiration from the ancient tradition of passing a communal drinking vessel to foster a sense of shared festivity. Their creation symbolises a victory that is held by an individual yet reflects the spirit of the broader community, including the team and fans, while also acknowledging the ephemeral nature of success.

The artistic process involved a blend of traditional sketching and advanced three-dimensional printing using nylon powder, which was subsequently painted and polished to a reflective finish. This commission is part of an ongoing annual project by Pirelli in collaboration with the Pirelli HangarBicocca Museum, now in its sixth edition. Previous artists who have contributed to this project include Alice Ronchi, Patrick Tuttofuoco, Ruth Beraha, Andrea Sala and Nico Vascellari.

Complementing the trophy, Pirelli Design has produced a special podium cap for the Monza weekend, featuring the iconic Azzurro blue of Italian sport. The cap, designed by Denis Dekovic, is adorned with gold embroidery and laurel wreaths, with the word Monza on the visor and an Italia 2026 emblem on the side. This exclusive merchandise is available for purchase online, adding a commemorative element for fans.

From a sporting perspective, the three softest tyre compounds will be available, with strategic simulations suggesting that a one-stop race is probable despite the availability of overtaking opportunities. The 5.793-kilometre circuit, characterised by long straights and low-downforce set-ups, will challenge drivers with energy management and rear axle traction, especially at the First Chicane and Ascari. While braking stability is crucial, the recently resurfaced track and new kerb modifications at specific turns will influence performance. Historical records highlight that Michael Schumacher and Lewis Hamilton share the most victories, Ferrari leads the constructors' tally and Pierre Gasly secured a memorable maiden win here in 2020.

Tyres Europe has released three summary reports detailing the findings of comprehensive Life Cycle Assessment studies focused on representative European tyre categories, including passenger-car, truck and bus, as well as retreaded and regrooved variants. The publications mark a significant effort to evaluate the environmental footprint of these products across their entire lifespan.

The assessments, executed by Sphera, utilised average industry data from multiple European manufacturers. The research framework examined environmental impacts spanning raw material extraction, production, logistics, usage and end-of-life disposal. Adherence to stringent international protocols, including ISO 14040 and ISO 14044, ensured methodological consistency, with an independent peer review further validating the conclusions.

For both passenger-car and truck tyre models, the operational phase emerged as the dominant factor in most impact categories, primarily due to fuel consumption linked to rolling resistance. Raw material processing constituted the second-largest burden. A notable finding revealed that a high-performance truck tyre exhibited an 8 to 27 percent reduction in environmental impacts relative to a medium-to-low-performance counterpart, attributed to superior rolling resistance and enhanced tread life.

The retreading analysis stressed that circularity must be balanced with use-phase efficiency, with findings based on scenario-driven break-even analyses due to limited measured data. The reports assert that tyre sustainability cannot be judged by a single metric, advocating a holistic view of materials, manufacturing, mileage, and rolling resistance. These insights aim to inform policy frameworks, including the Ecodesign for Sustainable Products Regulation and EU climate legislation.
