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.

The concluding day of 2026 F1 Pre-Season Testing at the Bahrain International Circuit saw Charles Leclerc set the overall fastest lap of the entire six-day programme. The Ferrari driver delivered a time of 1:31.992s on the C4 compound Pirelli tyres during the final hour of running, improving by eight-tenths of a second on the previous benchmark established by Kimi Antonelli. This performance placed him ahead of Lando Norris in the McLaren, who recorded a 1:32.871s on the C3 tyre. Max Verstappen and George Russell followed, with times of 1:33.109s and 1:33.197s, respectively, both also set on the C3 compound. Notably, none surpassed Leclerc's own leading time on that particular compound, a 1:32.655s. Pierre Gasly rounded out the top times, utilising the softest C5 tyres to post a 1:33.421s.

The C5 compound saw limited use on the final day, employed only by Alpine and Williams for short-run simulations. Aston Martin, despite having the tyre available, opted not to run it and instead completed just six laps on C3s before their session was curtailed. In contrast, teams focused on different aspects of performance. Gabriel Bortoleto and Arvin Lindblad set the pace on the harder C1 and C2 compounds, respectively. The day was also notable for the absence of several drivers, including Fernando Alonso, Lewis Hamilton and Alex Albon, who did not participate in any track action.

Beyond outright speed, teams dedicated significant effort to long-distance evaluation. Gabriel Bortoleto completed 25 laps on the C2 compound for Audi, while Esteban Ocon undertook 24 laps on C1s for Haas. Ocon was also the sole driver to run intermediate tyres, completing four laps to assess front wing behaviour. Over the entire six-day test, a total of 41,366 kilometres were covered across all 11 teams, a distance exceeding the Earth's circumference. The C3 compound proved the most popular, accounting for 61 percent of all laps. In total, 591 sets of slick tyres were utilised throughout the pre-season, with 326 of those deployed in the final three days alone.

Mario Isola, Pirelli’s Motorsport Director, said, “The radical changes introduced to the cars have inevitably shifted the teams’ focus towards power units and aerodynamics rather than tyres over the last few days. The final stages of testing are usually dedicated to optimising the car-tyre package, but it is clear some teams haven’t reached that point yet. Generally speaking, track feedback has been consistent with our simulation expectations. Drivers were able to gain confidence with the entire Pirelli range through both performance trials and long runs, even using the C4 and C5 compounds which aren’t particularly suited to a circuit like Sakhir.

“Mechanical resistance appeared strong across all options, with no signs of graining or blistering. Degradation levels are almost certainly higher now than what we expect for the Bahrain race, when temperatures will be lower and cars more developed. A central theme this season will certainly be balancing temperatures between the axles, especially ahead of the first race in Melbourne. The lower loads of a street circuit might require more intensive tyre preparation or differentiated tyre blanket temperatures, particularly in qualifying. In any case, it will be interesting to discover in Australia how much teams have been ‘sandbagging’ their engine power to avoid showing their hand. We only have to wait a couple of weeks to see the true pecking order.”

Radar Tires, a globally recognised manufacturer known for its off-road and high-performance products, is broadening its footprint in the light truck and off-road vehicle segment with a major expansion of its popular Radar Renegade-X line. Responding directly to robust market demand and the model's sustained success among enthusiasts, the company will introduce nine new sizes featuring rim diameters from 18 to 26 inches. A key highlight of this expansion is the debut of 26-inch options, catering to the growing trend of customised and lifted trucks requiring larger wheel fitments.

Since its market introduction, the Renegade-X has built a strong reputation for delivering uncompromising off-road capability without sacrificing on-road civility. Consumer feedback consistently praises its superior traction in mud and rocky terrain, its robust durability and notably low road noise – a combination rarely achieved in the mud-terrain category. This balance of aggressive performance and refined driveability has solidified its appeal.

The tyre’s distinctive design is the result of a collaboration with the renowned Italian design house GFG Style, blending engineering rigor with premium aesthetics. Its technical features include a high void-to-lug ratio designed for effective self-cleaning in mud, alongside a specialised rock-crawl compound for enhanced grip on varied surfaces. Durability is addressed through a three-ply sidewall construction, while a strategic combination of stone ejectors and serrations protects the tyre casing. Furthermore, sidewall lugs inspired by stealth design not only contribute to a striking visual profile but also improve lateral traction in challenging conditions.

The newly added sizes are intended for a wide range of vehicles, including Jeeps, pickup trucks and full-size SUVs. Availability is scheduled to commence through authorised dealers in February 2026, with additional sizes arriving through April of that year.

Rob Montasser, Vice President, Radar Tires, said, “The response to the Radar Renegade-X has exceeded our expectations, and our dealer partners have consistently requested additional sizes to meet customer demand. This nine-size expansion, including our first 26-inch rim diameter sizes, demonstrates our commitment to providing dealers with a comprehensive product offering that supports sustained, profitable growth while giving consumers more choices for their vehicles.”

Nokian Tyres has formally released its climate transition plan, a comprehensive roadmap guiding the company’s decarbonisation efforts. This strategy is anchored in the company’s near- and long-term climate objectives, which received validation from the Science Based Targets initiative in 2024. Crucially, the organisation’s ambition to achieve net-zero emissions across Scope 1, 2 and 3 aligns with the stringent requirements of limiting global warming to 1.5°C, as dictated by contemporary climate science.

The company has already made significant progress, particularly within its own operations. By the close of 2025, Nokian Tyres had successfully reduced absolute Scope 1 and 2 emissions by more than 38 percent relative to the 2022 baseline, edging closer to its interim target of a 42 percent reduction by 2030. The newly published plan elaborates on this trajectory, detailing the primary sources of emissions and the essential strategies for reduction both internally and across the broader value chain. These actions are designed to meet the 2030 benchmarks while maintaining a clear pathway towards the ultimate goal of net-zero greenhouse gas emissions by 2050.

Endorsed by the company’s Board of Directors, the plan is a living document subject to updates as emission-reduction technologies and methodologies evolve. Further details are accessible on the corporate website. This strategic approach is already yielding tangible results and external recognition. The company’s Romanian facility stands as the world’s first full-scale tyre factory to achieve zero CO2 emissions in its own operations. Furthermore, this commitment to sustainability was acknowledged in 2025 by TIME Magazine, which named Nokian Tyres one of the World’s Most Sustainable Companies, and by CDP, which awarded the firm its sixth consecutive leadership-level score for climate action.

Paolo Pompei, President and CEO, Nokian Tyres, said, “Our work towards net-zero emissions is not only about us but also about drivers worldwide. Through our actions and innovations, we reduce the environmental impact of tyre manufacturing while delivering the safety and quality that define Nokian Tyres.”
