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 has entered into a new collaborative agreement with the Rail Safety and Standards Board (RSSB), marking a unified effort to mitigate occupational road risks and enhance vehicle safety standards within United Kingdom's rail sector.

This initiative comes as data reveals that road traffic collisions were responsible for 3 out of 10 workforce fatalities in the rail industry over the five-year period leading up to 2024, underscoring the critical need for enhanced risk management.

In response, the Road Risk Group is spearheading sector-wide improvements by fostering collaboration, sharing safety methodologies and refining safety reporting and analysis. The group is also championing behavioural and cultural shifts within organisations while actively promoting the Occupational Road Risk Management Charter. This partnership recognises that effective risk management encompasses not only driver conduct but also vehicle maintenance and overarching safety culture.

Through joint educational campaigns and resources, TyreSafe and RSSB will encourage rail organisations to prioritise tyre condition as a fundamental component of their road safety strategies. This initiative directly supports the broader objectives of the Rail Health and Safety Strategy, which has identified occupational road risk management as a key priority for safeguarding the industry's workforce.

Lucy Powell, Strategy Manager at RSSB, who approved the partnership, said, “Road risk continues to be one of the most significant safety challenges facing the rail industry beyond the railway boundary. Partnering with TyreSafe enables us to strengthen awareness of one of the most critical elements of vehicle safety. Through education, collaboration and the sharing of best practice, we can help organisations better manage occupational road risk and support our industry’s commitment to protecting everyone who drives for work.”

Caitriona O’Brien, Workforce Health and Safety Manager at Network Rail and Chair of the RSSB Road Risk Group, said, “The Road Risk Group is committed to championing a stronger focus on managing occupational road risk across the rail industry. Working with TyreSafe brings valuable expertise that complements our strategic objectives, helping organisations place greater emphasis on vehicle safety as part of a wider culture of safe driving. By working together, we can continue to reduce preventable incidents and improve outcomes for everyone travelling on work-related journeys.”

Stuart Lovatt, Chair of TyreSafe, said, “We are delighted to become an official partner of RSSB and to support the important work of the Road Risk Group. Tyres are the only point of contact between a vehicle and the road, yet they are often overlooked in fleet safety programmes. By working with RSSB, we can help embed tyre safety into occupational road risk management across the rail sector, ensuring that employees and contractors understand the vital role that properly maintained tyres play in preventing incidents and saving lives.”

Yokohama Tire has renewed its environmental collaboration with the Surfrider Foundation’s North Orange County chapter through a recent coastal cleanup initiative at Seal Beach in Southern California. The joint effort resulted in the collection of dozens of refuse bags, with the total haul of hazardous waste exceeding 100 pounds (approximately 45.36 kg) removed from the local shoreline.

This beach restoration project represents the latest activity in a three-year partnership between the tyre manufacturer and the nonprofit organisation. The initiative falls under Yokohama’s broader corporate social responsibility framework known as the ‘Caring for our Communities’ programme, which coordinates various philanthropic endeavours.

Beyond the direct cleanup efforts, Yokohama continues to provide material support to the Surfrider chapter, including student club memberships, water quality testing kits, cigarette butt collection canisters and replacement equipment for harbour maintenance. The company maintains similar environmental partnerships with Tread Lightly! and the California State Parks Foundation alongside its ongoing work with Surfrider.

Alan Holtschneider, Senior Director of Marketing, Yokohama, said, “It’s been truly gratifying being a part of Surfrider Foundation’s North OC Chapter ongoing work to protect the environment, especially the beaches and oceans. We continue to volunteer on numerous projects with them, and the successful Seal Beach cleanup was another great example. It’s all part of Surfrider’s ongoing mission to protect and preserve the world’s ocean, waves and beaches for all to enjoy.”

George Manyak, longtime event coordinator for Surfrider Foundation North Orange County Chapter, said, “We really appreciate all the help Yokohama Tire has given us over the years. Their support has made a major impact on keeping our local beaches clean and safe for visitors to experience.”

Nexen Tire America has unveiled a comprehensive overhaul of its Next Level Associate Dealer Program, introducing structural changes designed to accelerate dealer qualification and enhance reward accessibility. The revised initiative directly responds to dealer input by lowering purchase thresholds and creating new earning opportunities for participants at various stages of engagement with the brand.

Central to the updated framework is a substantial reduction in the quarterly Tier 1 qualification benchmark, which has been decreased by 40 percent from 100 units to 60 eligible tyres per quarter. Additionally, a new introductory earning bracket has been established for dealers purchasing between 1 and 59 qualifying units, granting them USD two per tyre. The programme’s annual True-Up mechanism has also been expanded, allowing dealers who achieve year-end tier qualifications to receive volume bonuses for previous quarters where they initially fell short, with the 2026 annual qualifier reduced to 320 units.

Given the midyear implementation, Nexen has instituted a transitional qualification schedule for 2026, applying the former 100-unit standard to the first two quarters while the new 60-unit tier takes effect for the third and fourth quarters. To commemorate the programme’s relaunch, a Triple Dollars promotion will run from 1 July through 13 September, significantly increasing per-tyre payouts on select patterns, including the N’Blue 4S2, AH5, GTX, HP, CT8, AH7, AH8, N’Fera Sport, N’Priz S, N’Fera AU7, Roadian ATX, Roadian HTX2 and Roadian MTX models.

Participants can monitor their qualifying purchases, tier progression and total earnings through the Next Level online dealer dashboard. Complete eligibility criteria and payout structures are available through Nexen Tire America sales representatives, who can provide detailed guidance on the revised program provisions.

John Hagan, Executive Vice President – Sales, Nexen Tire America, said, “We listened closely to our Next Level dealers, and they have spoken about wanting a programme that makes it easier to qualify and provides more opportunities to earn. These changes deliver on that feedback by opening the programme to more dealers, allowing them to qualify sooner and begin earning rewards faster. We believe the new programme will help dealers grow their business with Nexen and ultimately strengthen our dealer network long term.”

FALKEN has released a new film titled ‘The Perfect Lap’, offering a gripping behind-the-scenes look at the team's recent campaign in the ADAC RAVENOL 24h Nürburgring. The film arrives following the team's 27th participation in the legendary endurance event, which took place this past May. It meticulously documents the intense operational rhythm within the pit lane and the unforgiving nature of the Nordschleife circuit, set against one of the world's largest motorsport gatherings, attracting over 450,000 spectators.

The documentary underscores the challenge of the 24-hour race, where contenders must execute between 156 and 162 nearly perfect laps to secure victory. Created with automotive film specialists FORMAT67, the production team spent six days capturing footage on the treacherous track. The use of a U-Crane camera rig enabled dynamic tracking shots following the FALKEN Porsche directly on the tarmac, delivering authentic and high-quality visuals.

Emphasising traditional filmmaking, the entire project was executed without artificial intelligence, from location shoots through post-production. This commitment to conventional methods was a deliberate choice to enhance the film's genuine credibility and emotional resonance. The film portrays a team defined by relentless determination, returning annually to pursue ultimate triumph in this iconic race.

Debuting in 1999, the FALKEN Motorsport Team has evolved into a front-running force at the Green Hell. Its greatest achievement remains a podium finish with third place in 2015, and the recognisable Porsche 911 GT3 R continues to be a fan favourite. With a history of ‘Top 10’ finishes and high-profile drivers, the team carries immense ambition, using compelling track footage to tell stories fuelled by emotion and the harsh realities of endurance racing.

Dennis Wilstermann, Marketing Manager, Dunlop Tyre Europe GmbH, which also includes the tyre brand FALKEN, said, “It was particularly important to us to give the film a classic, premium look while maintaining a timeless visual style. The film captures the unique atmosphere and intensity of the Nürburgring 24 Hours while also telling the story of a broader, recurring challenge in motorsport: the pursuit of the perfect lap.”

Evropi Dionysiadou, Brand Communications Specialist, Dunlop Tyre Europe GmbH, and responsible for the production, said, “The concept behind the film is to symbolise precision, passion, teamwork and the relentless drive to extract the maximum performance time and time again – lap after lap, day and night. In this respect, endurance racing and our complex film productions have a great deal in common.”
