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.

Michelin has prepared a six-part documentary series chronicling its 11-season tenure in MotoGP as its current stint as the championship’s sole tyre supplier nears its conclusion. Titled ‘Racing on Trust – A Decade of Michelin in MotoGP’, the production examines the manufacturer’s return to the premier class in 2016 through the perspectives of those directly involved, rather than focusing solely on results and statistical milestones. The first two episodes premiered on 8 October 2026, via the Michelin Motorsport and Michelin Group YouTube channels, with the remaining four instalments arriving weekly on Thursdays at 2:00 p.m.

The project assembles 25 figures from across the paddock who agreed to recount their experiences without editorial constraint. World champions, current and former riders, team principals, championship executives, journalists and Michelin Motorsport personnel contribute previously untold accounts spanning the 11 seasons. Among them, Valentino Rossi revisits the closing chapter of his career, Marc Márquez addresses his injury and subsequent recovery and Johann Zarco describes the circumstances surrounding his landmark victory at Le Mans. Their recollections, alongside those of peers and officials, trace both the evolution of the sport and the individuals who shaped it.

Contributors include riders Marc Márquez, Valentino Rossi, Francesco Bagnaia, Jorge Martín, Fabio Quartararo, Maverick Viñales, Cal Crutchlow, Jack Miller and Johann Zarco. Team and organisational figures comprise Lucio Cecchinello of LCR, Ducati Corse’s Gigi Dall’Igna, Alberto Puig of Honda HRC, Dorna Sports CEO Carmelo Ezpeleta, Loris Capirossi of race direction and Hervé Poncharal of Tech3. Media representatives include Sylvain Guintoli, Manuel Pecino, Simon Patterson, Guido Meda and Michel Turco, while Michelin Motorsport is represented by Piero Taramasso, Jean-Claude Catalano, Jean-Philippe Cappelle and Nicolas Goubert, with additional input from Maria Herrera.

The opening episode, ‘2016: The Comeback’, documents Michelin’s return and the formidable task of replacing the championship’s previous sole supplier at motorcycling’s highest level. The second, ‘Regain Trust’, examines how setbacks and difficulties ultimately reinforced confidence between the manufacturer, riders and teams, deliberately avoiding a narrative built exclusively around success.

‘Listen to the Bike’, scheduled for 15 October, begins on a wet circuit with limited grip before delving into rider sensation and feedback, illustrating a development cycle driven by continuous exchange among riders, engineers, teams and Michelin technicians. Breaking Point’, releasing on 22 October, covers the 2020 and 2021 campaigns, when the pandemic, Márquez’s injury and the arrival of a new generation reshaped the competitive hierarchy, a transition symbolically concluded by Rossi’s farewell after more than two decades.

‘A New Era’, arriving on 29 October, follows MotoGP into a fresh phase marked by increasingly capable machines and emerging talent, with Michelin advancing its tyres to extend performance boundaries. The concluding episode, ‘Final Sprint’, releasing on 5 November, reflects on 11 seasons of profound technological change and an exceptional human undertaking.

Throughout the six films, technology remains a constant presence, yet trust emerges as the defining thread, binding riders to their tyres, engineers to teams and, above all, people working together under the extreme pressures of competition.

The AZuR project group on chemical recycling convened its annual in-person meeting on 1 October 2026, bringing together more than 20 network partners at Pyrum Innovations AG in Dillingen/Saar. The gathering centred on recent scientific findings, the recovery of raw materials from end-of-life tyres, the European Tyre-to-Tyre initiative and collaborative projects planned for 2027. Participants examined how recovered carbon black and tyre thermolysis oil can be more effectively integrated into industrial production processes.

A scientific highlight came from Dr -Ing Sebastian Bogdahn, who presented his dissertation on the production and ecological assessment of high-quality carbonizates derived from used tyre thermolysis. His research combined experimental investigations, process modelling and life cycle assessment, with particular attention to recovered carbon black produced during thermolysis and subsequently processed. The findings indicated that the modelled system could potentially lower global warming potential relative to fossil-based carbon black production while underscoring the significance of process control, product quality and energy supply for environmental performance.

The European Tyre-to-Tyre initiative, launched in July 2026 by Pirelli, Pyrum, Synthos and BASF, illustrated how chemical recycling processes can be embedded within industrial value chains. Pyrum converts used and rejected tyres into recovered carbon black and tyre thermolysis oil through thermolysis. The processed carbon black is then used in Pirelli's tyre manufacturing, partially substituting fossil-based industrial carbon black.

At BASF, thermolysis oil is combined with fossil raw materials to produce chemical products including butadiene and styrene. Synthos utilises corresponding feedstocks to manufacture synthetic rubbers, which are subsequently employed in Pirelli's tyre production. According to the project partners, the entire value chain remains traceable via ISCC PLUS certification.

A notable feature of the meeting was a tour of Pyrum's thermolysis plants. Divided into three groups, attendees gained insights into the technical processes and engaged directly with on-site experts. The tour clarified the technical steps required for recovering and further processing raw materials, from the handling of used tyres through to the resulting product streams.

Management emphasised the value of regular AZuR in-person meetings, which combine exchange among companies, technology providers and research institutions with exposure to real industrial applications. The gathering demonstrated the importance of collaboration across the entire value chain, with research, technology development, industrial processing and tyre production considered together to transform recovered materials into high-quality raw materials for new products. The project group will continue this exchange in 2027 through concrete projects and information initiatives.
