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.

Evonik, a global speciality chemicals company, has outlined a three-year strategy to sharpen its focus and accelerate growth, assigning distinct roles across its business portfolio and setting specific tasks for its major German sites. Targeted growth projects are also intended to improve the group's geostrategic balance. To fund these investments, the company is relying on its Evonik Tailor Made restructuring programme to further reduce its cost base. The plan involves cutting 3,200 jobs worldwide, with roughly 2,150 of those losses falling in Germany.

At the annual strategy meeting, the executive and supervisory boards reviewed plans through 2030. Interim CEO Claus Rettig said the industry faces a structural and economic crisis, and Evonik will use this polycrisis to reshape old structures and improve its positioning. Many parts of the business are still growing, so efforts will concentrate on strengths, future topics and lucrative markets, with better cost positions creating room to manoeuvre.

Transformation will proceed at every level. Healthcare and biotechnology projects in Canada and Slovakia, worth several hundred million euros, will strengthen the portfolio, while business units are aligned by role as growth drivers or cash generators. A new business line, Designed Polymer Solutions, bundles growth areas in aerospace, automotive and gas separation, including biogas and hydrogen. Asia and America offer strong opportunities, and further investments there are under review. Each of the six major German sites will receive a clear profile, with implementation starting shortly.

Evonik is also exiting activities with no internal prospects. Rettig said long-term leadership requires leading in what the company does, and volatility demands flexible responses. Closures of smaller sites fit this approach, and divestments of C4 chemicals and infrastructure are progressing as planned. Tailor Made's second phase begins in 2027 and runs to 2029. Measures will be finalised by late 2026, including unfilled vacancies, early retirements and voluntary severance departures. Chief Human Resources Officer Thomas Wessel said Evonik has long lived social responsibility and maintained intensive dialogue with employee representatives, and this transformation will be completed together.

Continental recently showcased its new TerrainContact A/T2 tyre during a five-day driving event in Iceland, held from 14 to 18 September 2026. Journalists and invited customers tested the tyre across winding roads, rugged highlands, glaciers and volcanic terrain.

Starting at Þingvellir, the group travelled through Iceland's Western Highlands and the Kaldidalur valley, where gravel routes highlighted the tyre's blend of on-road comfort and off-road traction. The TerrainContact A/T2 targets pickup and SUV owners who mainly drive on pavement but require extra grip when conditions change.

Compared with its predecessor, the tyre offers better wet braking and snow traction while preserving a quiet ride and off-road ability. A new tread compound boosts wet performance, greater tread depth aids snow grip, and optimised zig-zag grooves and traction teeth add control on loose or snowy surfaces. It carries the Three-Peak Mountain Snowflake symbol and is engineered with electric vehicles in mind.

Okan Sen, National Marketing Manager, Continental Tire Canada, said, “The TerrainContact A/T2, as one of the best-balanced performance all-terrain tyres in the market, was developed for drivers who want the freedom to explore without compromising their everyday driving experience. Iceland was the perfect setting to bring that versatility to life, giving attendees the opportunity to experience the tire across the kind of changing terrain it was designed to handle.”

A new Oxford Economics study commissioned by Tyres Europe underscores the tyre sector's vital economic and social contribution, arriving as Brussels shapes its Industrial Accelerator Act to reinforce European industrial competitiveness. The report, titled ‘The Critical Importance of the EU Tyre Industry’, makes the case that EU industrial policy ought to encompass the finished products sustaining Europe's economy and essential services, rather than focusing solely on raw materials and technologies.

Through the lens of tyres, the research maps the relationships between European manufacturing capacity, reliance on external sources and the smooth operation of mobility, freight and public services. It concludes that EU-produced tyres potentially enabled freight, agriculture and passenger transport, directly yielding EUR 1.5 trillion in GDP – 9 percent of the EU's total – and providing work for 30.5 million people, 13 percent of EU employment.

The study further reveals exposure on both sides of the tyre value chain. Imported intermediate inputs constitute 11.9 percent of EU tyre production value, exceeding the EU economy average of 7 percent, while natural rubber supplies depend wholly on imports. In 2024, imported tyres made up 40 percent of newly fitted tyres across the EU, a proportion that continues to climb.

Adam McCarthy, Secretary General, Tyres Europe, said, “Economic resilience depends not only on access to materials but also on retaining the capacity to transform them into safe, advanced products in Europe. The Industrial Accelerator Act is an opportunity to recognise strategically-important finished products and support competitive manufacturing in Europe. A strong EU tyre manufacturing base reduces reliance on external suppliers and helps build a more resilient, competitive automotive value chain.”

Pete Collings, Managing Director, Oxford Economics, said, “Europe’s tyre industry is far more than a manufacturing sector: it is a critical enabler of mobility, trade and wider economic activity. Our analysis shows that EU-produced tyres support hundreds of billions of euros in GDP and millions of jobs across key customer sectors, while the industry itself depends on complex global supply chains. The findings underline the economic value of maintaining a strong European tyre manufacturing base.”
