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.

TyreSafe, UK’s leading independent tyre safety charity, has significantly expanded its industry backing with the formal addition of Dunlop and Falken to its roster of official supporters. The move arrives at a crucial juncture, as road safety advocates push for greater public awareness amid rising concerns over vehicle maintenance standards across the country.

Both brands bring considerable market weight to the charity, holding influential positions across premium, performance, SUV and light commercial vehicle categories throughout UK and Europe.

Lassa Tyres, the flagship international brand of Brisa, Türkiye's sector leader and tyre industry export champion, recently convened its international distributors for an exclusive event aimed at celebrating enduring partnerships and articulating its strategic growth trajectory. The gathering, which coincided with The Tire Cologne, brought together representatives from over 20 companies within the brand’s global network to reinforce synergy and mutual dedication.

Central to the brand’s vision is the ongoing enrichment of its product portfolio and technological transformation, designed to bolster competitiveness in key export markets. In response to shifting consumer demands abroad, Lassa Tyres is significantly expanding its winter and all-season offerings, complementing its established summer lineup.

The company has introduced four new winter tyres and one all-season tyre, marking a comprehensive overhaul of its winter range across all segments. These new products incorporate ‘EV ready’ and ‘NextGen’ technologies, aligning with the global industry shift towards larger rim diameters and the proliferation of electric vehicles. The updated winter portfolio is projected to satisfy approximately 85 percent of European market demand, with a particular emphasis on increasing availability in sizes 18 inches and above.

Brisa Chief Executive Officer Vecih Yılmaz underscored that sustainable global expansion relies on robust partnerships, affirming that the company continues to advance in international markets through locally responsive business models. This strategic approach reinforces Lassa Tyres’ commitment to meeting diverse regional needs while solidifying its presence in critical winter tyre segments worldwide.

Yılmaz said, "Driven by our commitment to continuously investing in and expanding our product portfolio in line with customer expectations, we are establishing a closer and more powerful connection with our customers through our expanding and enriched channel structure while enhancing our brand appeal among target audiences. Today, reuniting physically with our distributors at such a large-scale event is not only a celebration of our collaboration but also the most significant indicator that we are entering the new season stronger than ever with our completely renewed winter product portfolio.

AZuR network partner Genan has undertaken a significant strategic shift by divesting its tyre recycling facility in Houston, Texas, to concentrate exclusively on expanding its European footprint. The decision reallocates management focus and capital toward bolstering existing operations and penetrating new markets across the continent, effectively making Europe the sole theatre for the company’s future growth.

This corporate recalibration follows closely on the heels of Genan’s recently announced acquisition of a recycling plant in Weiden, Bavaria. That investment not only deepens the firm’s manufacturing base in Germany but also strategically enhances its logistical access to consumer and industrial markets throughout Central and Eastern Europe. Collectively, these moves crystallise a long-term commitment to establishing a robust European supply chain for high-quality secondary raw materials derived from end-of-life tyres.

The development arrives amid surging continental demand for recycled materials, with shorter supply chains and the imperative for resilient resource security driving the need for efficient domestic recycling capacity. Genan’s advanced mechanical processing technologies are positioned to address this gap, producing rubber granules, powder, steel and textile fractions that feed multiple industrial applications. The company’s role within the AZuR competence network further amplifies its impact, fostering joint innovation across repair, retreading and mechanical recycling stages.

Industry observers view Genan’s move as a clear endorsement of Europe’s ascendant position in the circular economy, where technological investment directly bolsters value creation and industrial know-how. Through collaborative efforts with research bodies and sector stakeholders, AZuR and its partners aim to strengthen the entire lifecycle of tyre materials, reinforcing the principle that closed-loop systems thrive on integrated, cross-sector cooperation.

Goodyear is significantly broadening its award-winning UltraGrip Performance 3 tyre line, expanding the range to 344 stock-keeping units across Europe. The addition of 66 new SKUs marks a major milestone, as the company now offers the most extensive winter tyre coverage available from a single tread pattern. This strategic move simplifies the selection process for customers while extending proven performance to a wider array of vehicles.

The European automotive landscape now encompasses everything from compact city cars to high-performance electric vehicles and large SUVs. With this expansion, Goodyear is establishing a new benchmark for how comprehensively a singular winter tyre design can address this evolving market. By achieving this broad coverage through one pattern, the brand differentiates itself from competitors who often require multiple designs.

The newly introduced SKUs represent entirely new fitment opportunities, allowing Goodyear to serve vehicle models previously beyond its winter portfolio. Over 90 percent of the new additions are in sizes of 19 inches and above, with the entire range now spanning from 14 to 23 inches to accommodate Europe's changing vehicle parc.

This growth reinforces Goodyear's presence in both replacement and original equipment markets, featuring 59 new replacement SKUs and 7 OE fitments. The replacement segment now includes options for models like the Volvo EX60 and BMW X3 M50, as well as electric vehicles such as the Škoda Elroq RS. New OE partnerships have been secured with major manufacturers, including the BMW iX3, Porsche Cayenne Electric and Mercedes-Benz GLC EQ.

The tyre's reputation is validated by securing first place in the ADAC Winter Tire Test for both 2024 and 2025, with ADAC predicting a lifespan of 76,500 kilometres. Strong braking and handling on snow, wet and dry roads are achieved through Snow Protect and Wet Grip technologies. Designed for both electric and traditional vehicles, the tyre also features reduced rolling resistance and lower interior noise for a refined driving experience.

Ben Glesener, Senior Technology Director, Product Development Consumer EMEA Goodyear, said, “Today’s winter tyre market is more complex than ever, with more vehicle types, sizes and requirements than before. By offering 344 SKUs within a single winter tyre pattern, UltraGrip Performance 3 cuts through that complexity, making it easier to choose a tyre that delivers proven performance across a wide range of vehicles.”
