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.

Kuraray America, Inc. (KAI) took part in the Women's Leadership Luncheon organised by the Economic Alliance Houston Port Region's Women In Alliance, held at San Jacinto College. The gathering drew women from throughout the Houston Port Region to exchange professional experiences, build connections and encourage the next generation of women leaders.

Andrea Cavalier, Principal Engineer at Kuraray America, Inc., noted that as she nears the later stages of her career, she has come to value how much can be learned from people at different points in their professional journeys. Her remarks underscored KAI's view that leadership growth is an ongoing process enriched by connections across career stages.

The event's centerpiece was a fireside chat titled ‘Beyond the Arena: Saddled for Success’, featuring Pat Mann Phillips, past Chairman of the Board for the Houston Livestock Show and Rodeo, with Nellie Baktashi Macaluso moderating. The conversation explored leadership, career development and spotting chances for personal and professional growth, highlighting three lessons: building trust through credibility and authenticity, embracing challenges by stepping outside familiar situations and knowing one's worth by recognising individual strengths and contributions.

Cavalier further stressed that leadership extends beyond personal success to using experience to create opportunities for others. That outlook mirrors Kuraray America's emphasis on mentorship, collaboration and continuous learning, where employees at all stages share knowledge and support one another.

Pirelli has unveiled the ANGEL GT III, a new radial Sport Touring tyre that combines easier, improved handling with enhanced wet-weather capabilities and more consistent performance across its service life while retaining the brand's sporting DNA. The rear tyre is built for greater durability and reduced rolling noise compared with other ANGEL family products, thanks to a new tread pattern, and it carries a high-contrast sidewall with the ANGEL symbol and Gran Turismo lettering.

Scheduled for availability from early 2027, the tyre is the fourth generation of the ANGEL family, which began with the ANGEL ST and evolved through the ANGEL GT and ANGEL GT II. Over the past 15 years, the range has helped raise standards in the radial Sport Touring segment for riders seeking a balance of sporty performance, riding enjoyment and long-distance touring capability, supporting Pirelli's steady expansion in one of the European market's most important segments. Each generation has brought technological and performance advances, earning growing rider recognition and strengthening the brand's presence.

Designed for modern mid- and large-displacement Sport Touring, Crossover and Naked motorcycles, the ANGEL GT III pursues a clear objective: Pirelli's interpretation of the Gran Turismo riding experience, with high levels of control, comfort and riding enjoyment. Dedicated work to reduce rear-tyre rolling noise further enhances touring comfort, an especially important consideration for long-distance riders, with the resulting reduction in fatigue benefiting both journey enjoyment and overall control.

The tyre's standout characteristic is improved easier handling, a trait particularly valued by riders in this category. Pirelli's designers aimed to make motorcycles feel more intuitive, smoother and less demanding in everyday use and on long journeys while preserving the precision and responsiveness of the brand's sporting DNA. Wet performance also received particular attention, with the tyre designed to deliver confidence and control on wet, low-grip roads, raising standards set by previous generations.

Consistency throughout the service life was another key focus. Extensive development work sought more uniform dynamic characteristics over time, even as wear increases, so riders retain high levels of control and enjoyment. While improving comfort and ease, the tyre remains true to Pirelli's heritage, its focus on sport performance, steering precision and support during spirited riding reaffirming a distinctive character over long distances.

Aesthetically, the ANGEL GT III evolves the family's visual identity, its new tread pattern reinterpreting signature ANGEL graphic elements while expressing clear stylistic evolution. The high-contrast sidewall, with the iconic ANGEL logo and Gran Turismo lettering, references an Italian motorcycling concept of travelling swiftly, comfortably and in style. Pirelli frames the launch as a new Sport Touring chapter and a renewed commitment to innovation and raising segment standards.

TyreSafe, UK’s leading tyre safety charity, has published an analysis of nearly 137,000 vans showing that a tyre advisory at MOT is a strong predictor of future dangerous defects, with the risk doubling for larger vans in the 3–3.5 tonne class. The organisation is calling on fleets to treat every advisory as a task requiring completion rather than a mere annotation on a certificate.

According to the study of DVSA MOT data, vans that received a tyre advisory were almost twice as likely to present a dangerous tyre defect at their next test. Roughly 1 in 14 vans with an advisory, or 7.0 percent, had a dangerous tyre defect at the following MOT, compared with about 1 in 28, or 3.6 percent, of those without an advisory. For vans weighing 3–3.5 tonnes, the figures rose to 6.3 percent against 3.0 percent, a doubling of risk that persisted even after accounting for vehicle age.

The scale of the problem is considerable. Of the nearly 27,600 vans issued a tyre advisory in February 2024, more than 1,900 returned in February 2025 with a defect graded Dangerous, a classification meaning the vehicle should not be driven until repaired. In around 3 in 10 van tyre failures, the issue had already been flagged at the previous MOT, suggesting the warning was often available in advance.

Roadside evidence reinforces the pattern. Tyres are the most frequent reason DVSA takes action against a van, and between April and June 2026 tyre condition was the top prohibition defect, recorded against 22.7 percent of vans inspected. Because DVSA targets vans suspected of being overloaded or unroadworthy, the figure is not representative of all vans, but it illustrates how often neglected tyres put a working vehicle out of service.

The business consequences are significant. With 4.89 million vans licensed in the UK covering around one mile in every six driven on British roads, and about one in five work-related collision vehicles being a van, employers face a clear legal duty to manage work-related driving risks. A van off the road also means missed jobs and lost income.

TyreSafe advises fleet managers to log every tyre advisory with a repair or re-inspection date, confirm and record its resolution, incorporate tyres into daily walkaround checks, set pressures according to manufacturer figures for the load carried and ensure wheel nuts are torqued and re-checked after any wheel removal. Drivers are urged to follow the ACT routine: checking air pressure with an accurate gauge, inspecting condition for cuts, bulges, cracks, embedded objects and uneven wear and verifying tread depth against the 1.6 mm legal minimum for vans up to 3.5 tonnes. The release is the first in a weekly series on tyre safety and fleet risk management.

Stuart Lovatt, Chairman, TyreSafe, said, “An MOT tyre advisory is an early warning, and our analysis shows it is a reliable one. Vans that get one are almost twice as likely to have a dangerous tyre a year later. That is a risk to the driver, to everyone around them, and to the business that depends on that van. Fleet managers already have this information on the MOT certificate. The fix is simple: treat every tyre advisory as a job with a deadline, and make sure drivers ACT on their tyres every day."
