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.

The Tire Recycling Foundation (TRF) has unveiled the recipients of its inaugural Circle of Change Awards, recognising initiatives that convert end-of-life tyres into sustainable materials with tangible community and environmental benefits. The honours, announced during a luncheon at the recently concluded 10th Tire Recycling Conference in Denver, Colorado, highlight growing momentum in end-use markets for recycled tire products.

North Carolina earned the Circular Economy Trailblazer Award for modernising its scrap tyre programme, including a revised funding framework that stabilises county recycling efforts, curbs illegal dumping and establishes a platform to incorporate tyre-derived materials into public works. The Innovation in End-Use Technology Award went to LHB Engineering and the St. Paul Port Authority for redeveloping a brownfield site in Minnesota, where roughly 30,000 yards of tyre-derived aggregate now support an underground stormwater system protecting the Mississippi River from runoff.

Michigan EGLE and its public, private and academic partners received the Market Development Excellence Award for a multi-sector effort using demonstrations and field data to advance tyre-derived aggregate, rubber-modified asphalt and porous pavements. The Value Chain Collaboration Award was presented to Bolder Industries and Pirelli Tire LLC for a closed-loop system that transforms manufacturing scrap tyres into recovered carbon black for new commercial tyre production, reducing emissions and resource use at scale.

The 2026 winning projects demonstrate that tyre recycling and tyre-derived products are established pillars of sustainability and economic growth, reinforcing the value of active state end-of-life tyre programmes focused on innovative market creation. The TRF Circle of Change Awards programme spans four national categories designed to spotlight leadership in advancing tyre recycling and the circular economy.

Stephanie Mull, Executive Director, Tire Recycling Foundation, said, “Every end-of-life tyre represents an opportunity to transform what would have been considered waste into something that strengthens our communities. This year’s winners are proof that when the industry works together, tyre recycling can simultaneously strengthen infrastructure, drive meaningful environmental progress and support local economies.”

Dick Gust, President, Tire Recycling Foundation, said, “What stands out about the 2026 winners is how embedded tyre recycling has become in real-world decision making. The success of these projects sends a clear signal that when recyclers, engineers, transportation agencies, state and local governments, manufacturers and private industry work together, end-use markets grow. That’s the integrated approach we need to continue building on.”

The Alliance for the Future of Tires (AZuR) is at the centre of a new industrial paradigm, as a recent study by the Boston Consulting Group (BCG) for the Federation of German Industries (BDI) confirms that the circular economy is becoming a decisive competitive factor for Germany. The analysis projects that circular gross value added could more than double from roughly EUR 60 billion (approximately USD 69.60 billion) today to up to EUR 125 billion (approximately USD 144.95 billion) annually by 2045, cumulatively unlocking an additional EUR 880 billion (USD 1.02 trillion) in value creation. AZuR interprets these findings as validation that recycling, reuse and extended product life cycles directly strengthen climate protection, supply security and industrial competitiveness.

A practical model of this transition already exists in the tyre recycling sector, where Germany generates around 50 million used tyres each year. Through professional repair, retreading and regrooving, many of these tyres could remain in use significantly longer before being mechanically or chemically recycled. AZuR actively champions keeping tyres and their raw materials in circulation across Europe, with the clear goals of avoiding waste, lowering CO₂ emissions, conserving natural resources and securing secondary raw materials for industry.

The effectiveness of extending tyre lifespan is illustrated by commercial vehicle retreading, which can increase mileage by up to 25 percent. According to an AZuR and DBU study conducted by the Fraunhofer Institute UMSICHT, retreading saves over 60 percent of CO₂ emissions, roughly two-thirds of raw materials and about 50 percent of the energy compared to new tyre production. Tyres no longer suitable for retreading are then mechanically processed into rubber granulate or chemically recycled via pyrolysis and devulcanisation, yielding valuable secondary materials for construction and new tyre products.

With more than 80 partners across the entire value chain, AZuR networks industry, small and medium-sized enterprises, science and recycling technology to develop concrete circular solutions. The BCG and BDI study thus confirms that the circular economy is not merely an environmental policy issue but a crucial growth driver for Germany’s industrial future, a role that AZuR believes the tire industry is uniquely positioned to lead.
