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.

DUNLOP Motorsport is all geared up for the 2026 ADAC RAVENOL 24h Nürburgring, scheduled to be held from 14 to 17 May 2026. At the legendary Nordschleife, the team will debut a Porsche 911 GT3 R bearing start number 17, marking the black-and-yellow car’s first appearance at the Eifel classic. A quartet of experienced drivers has been assembled to share the cockpit, including Frenchmen Julien Andlauer and Dorian Boccolacci, Belgian Alessio Picariello and Nordschleife specialist Nico Menzel.

A series of preparatory runs within the ADAC RAVENOL Nürburgring Endurance Series allowed the team to gather vital operational intelligence. Despite a rain‑affected delay to the opening round, the group managed to cross the line inside the top ten overall during its very first race. That outcome, combined with methodical calibration of the Porsche's suspension and aerodynamics, improved the squad's command of DUNLOP tyre behaviour under race conditions.

Unpredictable factors such as sudden showers, evolving asphalt grip and heavy lapped traffic frequently decide outcomes at the Nürburgring. Success therefore hinges on error‑free driving and disciplined strategic calls. The selected drivers bring precisely those attributes: Andlauer from his tenure in elite GT and prototype series, Boccolacci and Picariello from repeated Nordschleife campaigns, and Menzel from years of local expertise.

Several other entrants have also chosen DUNLOP rubber. Saugmotoren Motorsport will run the distinctive BMW Z4 E89, steered by Nordschleife veterans Ralf Schall and Christian Scherer. BLACK FALCON Team FANATEC, collaborating with Gran Turismo, enters a Porsche 911 GT3 Cup whose cockpit will be shared by Manuel Metzger, online personality Misha Charoudin and sim racers Steve Brown and Jimmy Broadbent. For spectators, the Boulevard area presents an interactive zone where Gran Turismo simulators offer virtual Nordschleife laps. A Porsche 962 C on loan from the Porsche Museum, winner of all five Supercup races in 1987 and that year's champion, will also be exhibited.

The ADAC RAVENOL 24h Nürburgring starts Saturday 16 May at 3:00 pm. Fans unable to attend can watch live via the official stream or on RTL Nitro. DUNLOP Motorsport also shares regular updates and content from the Eifel region through its social media channels.

Pirelli has developed a new rear tyre solution for the fifth FIM Superbike World Championship round at the Czech Republic’s Most circuit. The track is known for unusually high mechanical strain on rubber, particularly at the rear axle. To address this, Pirelli created the F0468 medium compound rear specification. Its compound matches the D0922, a tyre used at Most in 2025 and at Phillip Island across the previous two seasons. However, the F0468 features an entirely new internal structure for better race-long consistency and improved stability.

This newcomer evolves the E0829 specification, which shared the same compound and appeared at Phillip Island earlier this year. Riders who dislike the F0468 can still choose the D0922 development rear tyre. That option has already proven itself at the unique Czech layout and at Phillip Island, another tyre‑killing circuit. For qualifying and the Superpole Race, Pirelli has designated the standard soft SC0 as the reference rear tyre.

Beyond the premier class, Supersport and SportBike World Championship competitors will also race at Most. Supersport riders receive the same front choices as Superbike: soft SC1 and medium SC2. At the rear, Supersport entries can pick the soft SC0 or the medium SC1. SportBike competitors have used that same medium SC1 on both axles all season.

The tyre lineup thus gives every category familiar options alongside the new F0468. By blending a proven compound with a revised structure, Pirelli targets greater performance consistency without forcing riders to abandon the trusted D0922. Most’s punishing layout will serve as the ultimate test for both solutions.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “Over more than two decades as supplier to the Superbike World Championship, Pirelli has built an extremely solid and versatile tyre range. The SCX supersoft rear solution now represents an absolute benchmark for riders and is used in most races on the calendar, with the soft SC0 becoming a valid alternative on some occasions. There are, however, some circuits that are particularly demanding on tyres, such as Phillip Island and Most, which by virtue of their layout and intrinsic characteristics require more specific solutions and more durable compounds, typically medium options.

“In these cases, development work focuses on improving key parameters such as performance and consistency over race distance: objectives that guided the design of the new rear solution in F0468 specification. To complete the allocation, riders will in any case also have the well-proven D0922 option available, which has shown that it can effectively handle the particular stresses imposed by this circuit. It will be interesting to assess whether the new F0468 medium will be able to raise the performance level beyond that of the D0922 further still.”

Balkrishna Industries Ltd (BKT) has unveiled an ambitious expansion and investment roadmap aimed at more than doubling its revenue to around INR 230 billion by FY30, backed by a cumulative capital expenditure of INR 68 billion.

The company said the investment programme would strengthen its leadership in the off-highway tyre (OHT) segment, expand carbon black capacity and accelerate its entry into India’s on-highway tyre market. The strategy forms part of BKT’s long-term plan to achieve an estimated 8 percent global market share in the OHT segment by FY30.

BKT has already announced INR 13 billion of capex for OHT tyres in August 2024 and an additional INR 35 billion investment in May 2025 for on-highway tyres, rubber tracks, carbon black and power plant expansion. The board has further approved INR 20 billion in additional capex to support capacity expansion, infrastructure development, AI-enabled automation and sustainability initiatives.

As part of the OHT expansion strategy, BKT said ongoing debottlenecking and capacity enhancement initiatives would raise OHT tyre capacity to 425,000 metric tonnes per annum (MTPA). The company is also expanding its dedicated rubber tracks manufacturing facility while strengthening its mining tyre portfolio.

In the carbon black business, the company is scaling up production to improve raw material integration and energy efficiency. BKT said Phase 1 capacity has already been increased to 265,000 MTPA along with a 24 MW cogeneration power plant, taking total cogeneration capacity at Bhuj to 64 MW. Phase 2 expansion, which will raise carbon black capacity to 360,000 MTPA, is expected to become operational in Q1 FY27.

The company is simultaneously building its on-highway tyre business in India through a modular approach focused initially on premium passenger car radial tyres and commercial vehicle radial tyres. Commercial vehicle radial tyres were pilot launched in Q4 FY26, while passenger car radial tyres are scheduled for pilot launch in Q3 FY27.

For FY26, BKT reported standalone revenue of INR 106.56 billion, while net profit stood at INR 12.22 billion. OHT sales volumes rose 1 percent year-on-year to 317,356 MT.

The company said the expansion programme is expected to enhance profitability through stronger operational integration, scalable infrastructure and an expanded product portfolio, with blended EBITDA margins projected in the 23–25 per cent range after full commercialisation of the new capacities.
