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.

Tyres Europe, as part of a coalition of 10 European associations representing consumers and automotive and mobility service providers, has issued a joint press release welcoming the latest CARUSO Connected Vehicle Field Test assessing the EU Data Act’s implementation across 29 major vehicle manufacturer groups. The findings confirm the legislation established important principles for accessing vehicle-generated data and encouraged some manufacturers to engage for the first time. One year on, however, the framework remains insufficient alone to enable a competitive, innovative connected mobility market.

Covering 15 automotive use cases across 28 vehicle manufacturer groups, the study concludes that while data access has improved, conditions for competitive, scalable, multi-brand services are still lacking. Access remains fragmented, inconsistent and often commercially or technically impractical across the car parc. Limited third-party access, differences in data scope, quality and coverage, and restrictive commercial terms continue to undermine the business case for innovative services. Genuine multi-brand development remains unattainable, preventing consumers and businesses from fully benefiting from connected mobility.

For many manufacturers, implementation has become a compliance exercise rather than a genuine effort to enable market access. Independent providers face limited datasets, restrictive terms, manual approvals, manufacturer-specific consent mechanisms and inconsistent technical solutions. Such approaches may satisfy the Data Act’s broadly defined obligations but are incompatible with the real-time, automated access modern digital services require.

Strong enforcement matters. Manufacturers respond faster where national authorities investigate complaints and apply enforcement mechanisms. Without consistent, harmonised, proactive enforcement across the European Union, Data Act rights risk remaining largely theoretical for a significant share of Europe’s vehicle fleet.

The coalition urges European Union institutions and Member States to enforce the Data Act consistently, issue clear guidance on fair, reasonable and cost-based compensation and use forthcoming reviews to reinforce rather than weaken it. Dedicated automotive legislation should establish common access conditions, interoperability requirements, initial technical and data delivery standards and safeguards against discrimination. Effective access must cover vehicle-generated data and the in-vehicle functions and resources needed to develop, scale and deliver digital mobility services, enabling fair competition, growth and investment.

According to the coalition, the Data Act was an important first step, but horizontal legislation alone cannot create a workable multi-brand market. Implementation varies widely: of 28 manufacturers, nine (32 percent) have barely implemented the Act; 18 (64 percent) lack adequate third-party pricing; 18 (64 percent) lack adequate data provision; and 19 (68 percent) lack an adequate API solution. Sixteen manufacturers (57 percent) enable none of the use cases, while only nine support the most feasible ones. Without stronger enforcement and dedicated automotive legislation, Europe will fall short of its innovation, consumer choice and fair competition ambitions.

CEAT reported a 26 percent year-on-year increase in consolidated revenue to INR 47.62 billion in the second quarter of the 2026-27 financial year, while net profit stood at INR 1.12 billion as higher raw material costs continued to weigh on the tyre maker.

The company’s consolidated earnings before interest, tax, depreciation and amortisation (EBITDA) margin was 9.5 percent, according to its unaudited results for the quarter ended 30 September.

Arnab Banerjee, Managing Director and Chief Executive, said revenue growth was supported by premium segments across business units. He added that the conflict in West Asia had kept raw material costs high, prompting the company to tighten cost controls.

CEAT expects to deliver double-digit revenue growth in the second half of the financial year, alongside further price increases, Banerjee said.

On a standalone basis, revenue rose 23 percent year on year to INR 45.48 billion. EBITDA margin was 10.14 percent, while net profit reached INR 1.64 billion.

Kumar Subbiah, Chief Financial Officer, said commodity costs were expected to remain elevated in the third quarter. The company would continue to pursue measured price increases and improve its product mix to manage cost pressures.

Subbiah said debt increased during the quarter, largely because of capital expenditure of close to INR 4.9 billion to expand capacity in areas with high utilisation, as well as dividend payments.

He added that CEAT would maintain financial discipline while investing to meet demand and support profitable growth.

Pirelli has completed the renewal of its winter range with the Scorpion Winter 3, a tyre developed for SUVs in cold-weather conditions. That segment now accounts for more than half the global market and brings distinctive traits, notably greater weight and a higher centre of gravity, which demand dedicated internal structures and tread patterns.

The result is a tyre balancing performance across the many conditions of winter, from snow and wet roads to dry asphalt. It overcomes a traditional winter tyre compromise, giving SUV drivers consistent strength even in demanding situations, a claim already supported by a first independent test that ranked it best among its competitors. At launch, every size carries an A wet-grip rating on the EU tyre label, with noise between classes A and B. For the growing electric and plug-in hybrid portion of this segment, Pirelli also offers Elect technology, engineered specifically for those powertrains.

Development began with how tyres behave under heavy loads. The contact patch was redesigned to optimise pressure peaks, critical for mileage and even wear on heavy vehicles. This produced the generation's first major innovation: as the tread wears, the active edges within the contact patch, and therefore snow and wet grip, stay consistent over time. A dedicated carcass and tread design were likewise engineered for high vehicle weights.

The tread geometry adopts several Cinturato Winter 3 solutions, that tyre having recently won a test by the independent German association ADAC. These include a zigzag central groove for water evacuation and lateral snow grip, patented Snow Keeper Teeth that retain snow in the grooves to exploit snow-on-snow contact, and a high void ratio that aids snow and wet performance while countering aquaplaning. SUV-specific additions include stiffer tread blocks for handling and wear resistance under load, plus calibrated sipe density to preserve dry-road behaviour.

The compound draws on P Zero Winter 2 experience, using specific polymers such as Dual-Core Polymer, whose dual mechanism improves grip across conditions, while plasticisers broaden the operating temperature range. Engineers at Bicocca made extensive use of advanced Virtual Development techniques, simulating variables for precise results while cutting development time and prototypes, and driving simulators from static to dynamic helped target dry handling and enjoyment. The Pirelli Sottozero Center in Swedish Lapland enabled year-round snow and ice testing, partly indoors.

Launching in 30 sizes from 18 to 22 inches, the tyre offers Elect technology, which can raise electric and plug-in hybrid range by up to 10 percent, the Pirelli Noise Cancelling System that reduces perceived cabin noise via internal sound-absorbing material and Seal Inside for pressure retention after external punctures. It joins the Scorpion family begun in 1986 for high-riding vehicles and first fitted to the Lamborghini LM002, now spanning summer, winter and all-season road and off-road products with a strong original equipment focus. It adds to more than 1,200 homologations, including bespoke work for Aston Martin, Porsche, Lamborghini, Lotus, Audi, BMW, JLR and NIO. With winter tyre or snow chain rules starting 15 November, it completes a Winter range fully renewed over two years, alongside P Zero Winter 2 and Cinturato Winter 3.
