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 Industry Project (TIP) has announced the selection of five research proposals under its inaugural Open Call for Projects (OCP), awarding nearly USD 2 million in total funding. This initiative, designed to advance the global scientific understanding of tyre wear emissions and their mitigation, also coincides with the launch of a second funding round focused on ecological impacts.

The first OCP, which concluded in late 2024, attracted 22 submissions over a four-month period. An evaluation committee composed of TIP experts and external technical assessors selected the five awardees based on stringent criteria, including scientific relevance, methodological feasibility, innovation and potential societal impact. Three of the chosen projects will advance research into the environmental pathways and presence of tyre wear particles. These are led by institutions including Germany’s Technical University Darmstadt, which will map pollution in roadside soils; France’s Gustave Eiffel University, investigating particles in sewer systems and the Helmholtz Centre for Environmental Research, developing a new high-throughput method for detecting particles.

The remaining two projects are focused on developing practical mitigation solutions. Washington State University will research using tyre char to treat stormwater runoff, while the non-profit Ocean Conservancy will evaluate the effectiveness of green infrastructure in urban areas to capture tyre wear pollution.

Concurrently, TIP has launched its 2025 Open Call for Projects, which will specifically address significant knowledge gaps concerning the potential ecological impacts of tyre wear emissions, including chemicals and leachates. This new focus is informed by TIP’s recent State of Knowledge paper series, which highlighted inconsistencies in the current scientific understanding. To support prospective applicants, TIP will host introductory webinars on 23 September 2025. The final deadline for proposal submissions to this global collaborative initiative is 15 January 2026.

Larisa Kryachkova, Executive Director, TIP, said, “The topic of tyre wear emissions is extremely complex – one that requires deep, evidence-based investigation and cross-stakeholder collaboration. Recognising this, we decided to complement our own research and mitigation initiatives by launching the Open Call for Projects, inviting stakeholders across the world to join us in the quest to uncover this multi-dimensional subject. The initiative reflects our long-term commitment to building a collaborative research ecosystem through public platforms. The OCP takes us one step forward in harnessing the collective brainpower of the scientific community and we look forward to evolving this further in the coming years.”

Dr John Bucher, part of TIP’s Assurance Group and a member of the OCP evaluation committee, said, “Sound science and robust evidence are essential to assessing the environmental challenges we face and to identifying the most effective solutions. Initiatives such as the OCP can act as a tremendous catalyst in this regard, opening a new world of possibilities. We are pleased with the diversity and quality of submissions received, which reaffirms the strong interest in this topic and the desire to engage in collaborative solutions.”

Apollo Tyres Ltd has announced a comprehensive price reduction across its entire product portfolio, effective from 22 September 2025. This strategic decision is a direct response to and aligned with the recent fiscal reforms enacted by the GST Council, which approved a substantial reduction in the Goods and Services Tax (GST) rates for the tyre industry.

The revised tax structure slashes the levy on new pneumatic tyres from a previous rate of 28 percent down to 18 percent. In a more pronounced reduction aimed at supporting the agricultural community, the GST on tractor tyres and tubes has been lowered to just five percent. The company has emphasised its commitment to ensuring that the full benefit of these tax cuts is passed through directly to the end consumer, reflecting a customer-centric approach to the policy change.

Apollo Tyres' subsequent price adjustment will be applied universally across all its product lines. This includes tyres for passenger cars, commercial vehicles, two-wheelers and off-highway and agricultural vehicles. The broad-based price cut is anticipated to have a widespread positive impact on vehicle ownership and operational expenses. To guarantee a smooth and uniform transition to the new pricing model across the country, Apollo Tyres has already initiated a coordinated effort with its extensive network of distributors and retail partners, ensuring the revised prices are effectively communicated and implemented at all points of sale.

Rajesh Dahiya, Vice President – Commercial (India, SAARC and Southeast Asia), Apollo Tyres Ltd, said, “We welcome the GST Council’s progressive decision, which will bring tangible benefits to both the industry and end-users. In keeping with our commitment to transparency and customer value, we are transferring 100 percent of the tax benefits to our consumers.”

Fuelled by robust domestic vehicle production, aftermarket demand and a surge in automotive exports, India's tyre industry is poised for transformative growth. A joint vision from the Automotive Tyre Manufacturers’ Association (ATMA) and PwC India projects that by 2047, production volumes could quadruple, while revenue is expected to multiply 12-fold to an estimated INR 13 trillion. This exponential financial expansion will be driven by a shift in the industry's revenue mix towards more premium products, rising raw material costs, a growing export share, the transition to electric vehicles and the emergence of servitisation models.

To achieve this ambitious vision, a strategic framework termed CHARGE has been proposed. This approach focuses on six critical levers: enhancing Customer relevance, upholding high-quality standards, fostering adaptability, building resilience through resource efficiency, driving growth via innovation and empowering strategic alliances. The framework is designed to help tyre manufacturers become more agile, customer-centric and technologically advanced to improve operational efficiency and global competitiveness.

Domestic growth will be primarily driven by strong original equipment and replacement markets. Rising incomes are boosting passenger and two-wheeler sales, while significant infrastructure investment is increasing commercial vehicle demand, in turn supporting aftermarket tyre sales. However, challenges such as domestic natural rubber availability and new mobility technologies could impact growth.

Concurrently, tyre exports are positioned for substantial expansion. Key strategies to accelerate international growth include innovation for specific use cases, securing new free trade agreements and enhancing cost competitiveness and brand perception. Nevertheless, exporters must navigate obstacles like volatile regulations and non-tariff barriers.

A significant trend will be the rise of servitisation, where fleet operators increasingly adopt professional tyre management services. Demand for these solutions, including tyre health monitoring and advisory services, will be driven by a focus on operational efficiency and customer requirements. For this market to reach its full potential, tyre companies must develop scalable, economically viable models while addressing data security and regulatory concerns.

Kavan Mukhtyar, Partner and Leader – Automotive, PwC India, said, "India’s journey towards Viksit Bharat 2047 presents a huge opportunity for the tyre industry, not only to meet the aspirations of its domestic customer base but also to exponentially scale up tyre exports, especially in the commercial vehicle and passenger vehicle segments across key markets like US and EU. Emerging consumer trends and mobility shifts, a dynamic global business environment and sustainability imperatives present a unique opportunity for the Indian tyre industry to transform itself and drive sustainable growth through 2047. Innovating at speed for global markets through advanced material engineering, finding sustainable alternatives for natural rubber and addressing sustainability imperatives throughout the value chain will be key to unlocking growth potential for the industry. Additionally, brand strengthening in export markets and investing in digital technologies across the value chain will be essential to drive productivity and a sustained global competitive advantage.”

Arun Mammen, Chairman, Automotive Tyre Manufacturers’ Association (ATMA), said, "The Indian tyre industry stands at the cusp of a transformational journey, driven by rapid economic growth, evolving mobility trends and an expanding global footprint. The findings of the ATMA-PwC report underscore the industry’s immense growth potential, with revenue projected to grow 12-fold by 2047. This growth will be fuelled by a shift towards premiumisation, sustainability-led innovation and a strong focus on technology and exports. As we move towards ‘Viksit Bharat 2047’, the tyre industry is poised to play a pivotal role in enabling India’s automotive ambitions to build a resilient and future-ready sector."

Sanjay Dawar, Partner and Leader – One Consulting, PwC India, said, “The Indian tyre industry is at an inflection point, with the potential to create significant economic value and strengthen India’s global competitiveness. Achieving this 12-fold revenue growth will require a holistic approach – one that brings together innovation, sustainability, digital transformation and strong partnerships across the ecosystem. At PwC, we are committed to working alongside industry stakeholders to co-create strategies that can accelerate momentum, build resilience and help realise the Viksit Bharat 2047 vision."
