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.

Liberty Tire Recycling has published the industry’s first US company-commissioned lifecycle assessment (LCA) centred on rubber-modified asphalt solutions made from recycled tyres. The study was commissioned by Liberty and carried out by Boundless, applying internationally recognised LCA methodology to evaluate the environmental impacts of the company’s asphalt-related products against conventional alternatives used in asphalt modification.

The company described the assessment as a notable step forward for rubber-modified asphalt. Environmental gains are routinely linked to recycled tyre materials in road building, yet Liberty said this analysis supplies quantified evidence behind such assertions. Greenhouse gas emissions tied to its rubber-modified asphalt solutions were tracked throughout their lifecycle.

Results showed that Liberty's asphalt products carried substantially lower greenhouse gas impacts than conventional SBS polymer modifiers. Recovering and reusing end-of-life tyre materials was also found to deliver environmental benefits exceeding the impacts of processing them. Liberty said the findings give transportation agencies, engineers, contractors and infrastructure stakeholders data-driven insights for choosing materials.

Four products were assessed: crumb rubber and three asphalt additives, namely dry mix rubber additives, a DOT additive and combined micronised rubber powder with the Rheopave additive. Dry mix rubber additives yielded the largest carbon benefit, avoiding up to 0.577 kg CO₂e per pound produced, while the tyre-derived products achieved over 100 percent lower greenhouse gas footprint than traditional SBS modifiers. Each product assessed generated a net environmental benefit, with reductions spanning 0.47 to 0.57 kg of CO₂e per pound.

Liberty said the study helps set a benchmark for measuring and communicating environmental impacts as sustainability gains prominence in infrastructure projects, and that transparent, science-based data will matter increasingly to public agencies and industry leaders weighing performance and environmental goals.

Avon Tyres will make its second consecutive EICMA appearance this year, using the Milan show to unveil a refreshed motorcycle range and a renewed brand identity to a global audience of riders and trade visitors. The company will occupy Hall 9, Booth U65 at Fiera Milano between 3 and 8 November.

The exhibit reflects Avon's ‘made to be different’ philosophy and presents a focused portfolio spanning sport, touring, adventure, cruiser and classic segments. Avon's return also signals progress within Goodyear's motorcycle portfolio, where, since joining the family of brands in 2022, it has paired longstanding heritage with a modern product strategy and upgraded manufacturing.

Four flagship tyres anchor the display: the Spirit ST for sport-touring, the 3D Supersport for hypersport riders, the Roadrider MKII for classics and the Cobra Chrome for cruiser, touring and custom applications, the latter now offered in additional sizes. They are joined by the Trailrider 2, a new adventure-touring tyre launching in January 2027 that carries the ‘made to blaze your own trail’ message, targets an 80:20 road-to-off-road mix and will come in at least 20 sizes for popular adventure bikes.

Together with the existing Trekrider and Streetrunner, the lineup forms Avon's most comprehensive public display of its motorcycle portfolio to date. EICMA, which drew over 600,000 visitors last year including nearly 43,000 trade professionals from 167 countries, gives the brand a truly global stage for engaging riders, dealers and partners. Public-day attendees can also meet stunt rider Rok Bagoros at the stand on Friday 6 November at 11:30.

Roberto Finetti, Marketing Manager Motorcycle Europe, Goodyear, said, “We’re looking forward to speaking with riders and partners at EICMA about our continued growth plans for Avon. EICMA is the world’s largest motorcycle exhibition and provides the ideal place to showcase our refreshed identity and tyre range under the ‘made to be different’ philosophy.”

Kumho Tire USA has announced that its driver Jack Shanahan finished third overall in the 2026 Formula DRIFT PRO Championship, concluding a strong second season with a runner-up result at Round 8, the Shoreline Showdown, held in Long Beach, California. Competing on KUMHO Ecsta V730 tyres, Shanahan entered the season finale as the top qualifier and recorded his fourth podium of the year in his E82 BMW.

After securing first place in qualifying, Shanahan collected four championship points and received a bye through the Top 32 round. He then won three head-to-head battles to reach the Finals, where he met five-time PRO Champion James Deane in a tightly fought contest. While attempting to stay close to Deane’s Mustang, Shanahan spun in Zone 6 and ultimately took second place at the Shoreline Showdown.

The KUMHO Ecsta V730 is an extreme-performance summer tyre designed to deliver exceptional grip, responsiveness and consistency in demanding track conditions, making it well suited to competitive motorsports and driving enthusiasts.

Ed Cho, CEO, Kumho Tire USA, said, “Jack has delivered an outstanding season, and we couldn’t be prouder of what he’s accomplished in just his second year competing in Formula DRIFT. His four podium finishes and third-place championship standing are a testament not only to his talent and determination but also the reliable performance of our Ecsta V730 tyres. We’re proud to support Jack as he continues to establish himself among the sport’s top competitors.”

Shanahan said, “What an incredible year it’s been for our small but mighty team. To finish second at the final round and third overall in the championship exceeded all our expectations heading into the 2026 season. Having the grip, consistency and reliability of the KUMHO Ecsta V730 tyres gave me the confidence to push my limits every round and I couldn’t be prouder of what we’ve achieved together.”

The all-new Vredestein Quatrac Pro 2 premium ultra-high-performance all-season tyre has had its class-leading capabilities confirmed through independent testing in Spain and Finland. The tyre established new benchmarks for wet braking and recorded the fastest snow handling lap times against four leading all-season rivals.

Testing in Finland at the UTAC winter facility used a sensor-equipped BMW 5 Series to measure speed and lap times, with all tyres subjected to identical procedures. The Quatrac Pro 2 achieved the quickest snow handling lap, showing exceptional grip, balance and controllability, which testers praised for excellent response and stability in all circumstances. Its snow performance is aided by 3D interlocking sipes at the shoulder, whose zig-zagged inner faces in horizontal and vertical planes limit tread block movement.

In Spain, Applus+ IDIADA assessed dry and wet handling and braking on certified asphalt with defined water depth. The tyre outperformed key competitors in wet conditions, delivering a 7 percent wet-braking advantage over one long-established segment rival, and separate testing confirmed an A wet-grip rating across the entire size range, unique in the UHP all-season segment. Four longitudinal grooves in every size, also unique in the category, plus directional lateral grooves, support water evacuation and aquaplaning resistance.

Compared with its predecessor, abrasion resistance has improved by 8 percent to maximise tyre life, while rolling resistance is reduced by 10 percent to boost driving range, underlining suitability for electric vehicles. The Quatrac Pro 2 is available now for wheel diameters from 17 to 24 inches, with section widths up to 355 mm for powerful passenger vehicles.

Daniele Lorenzetti, Chief Technology Officer, Apollo Tyres Ltd, said, “Vredestein has long been recognised for its premium all-season tyres, and these independent tests reinforce that reputation. The Quatrac Pro 2 delivered exceptional grip and traction against other premium competitors while also improving efficiency and longevity compared with its predecessor.”
