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.

Hankook Tire has secured a notable second-place finish in the Auto Bild winter tyre test published in issue 44 dated 29th October 2026, with its Winter i*cept RS 3 earning an overall score of 1.4 and an ‘Exemplary’ rating in the widely used 205/55 R 16 size. The strong showing placed the premium manufacturer's offering second among the 14 winter tyres evaluated.

The German motoring publication conducted its assessment using a Volkswagen Golf as the test vehicle, examining each contender's braking, handling and safety performance across snow, wet and dry surfaces. Rolling resistance and drive-by noise formed part of the broader evaluation programme as well.

The Winter i*cept RS 3 proved especially formidable in aquaplaning disciplines, recording the field's best lateral acceleration in curves and the second-highest aquaplaning onset speed, prompting testers to describe it as an aquaplaning specialist while also noting its fair price. It ranked among the top three for snow traction and snow slalom, and stopped from 50 kmph on snow in 24.1 metres, with wet braking from 100 kmph measured at 47.4 metres, underscoring balanced everyday winter capabilities.

The tyre's design incorporates a generous shoulder zone for improved traction and lateral guidance during snow-covered cornering, while an inverse V-shaped tread and special 3D sipes deliver short snow braking distances. High tread rigidity bolsters safety on icy roads, and fine tread grooves on the blocks facilitate rapid water evacuation to reduce aquaplaning risk.

The German Rubber Industry Association (wdk) has urged policymakers in Berlin and Brussels to give the rubber sector a more prominent role in industrial, security and raw materials strategy. Speaking at the association's autumn conference in Frankfurt am Main before roughly 200 company representatives, wdk President Michael Klein argued that rubber serves not only mobility but also security and defence.

Elastomer products such as seals, hoses, membranes and vibration dampers are essential to the operation of modern industrial plants as well as military vehicles, aircraft and logistics infrastructure. Though frequently overlooked, their failure can cripple entire technical systems. Klein therefore called for the rubber industry to be included in security and defence planning at an early stage, particularly regarding the safeguarding of production capacity, raw material supplies and technological know-how. He described industrial resilience as an integral part of national resilience, warning that capabilities not maintained in peacetime cannot be restored quickly during a crisis.

The wdk identifies raw material supply as a pressing concern, contending that Germany and Europe need an independent rubber raw materials strategy covering both civilian and military crisis preparedness. Such a strategy would entail long-term, diversified supplier relationships, strategic reserves of critical raw materials and intermediate goods and the preservation of European processing and blending capacity.

Klein also renewed calls for a sustained improvement in industrial location conditions, citing competitive energy prices, faster permitting, meaningful reductions in bureaucracy and dependable investment frameworks as prerequisites for retaining industrial value creation in Germany. He stressed that economic growth stems from trust rather than regulation.

The Goodyear Tire & Rubber Company closes its FIA World Endurance Championship campaign this weekend as the 6 Hours of Monza returns, marking the final race for the current Goodyear Racing Eagle LMGT3 tyre specification. Although the Milan-area circuit has appeared on the WEC calendar before, this is its debut in the LMGT3 era, and the November scheduling should deliver markedly cooler conditions than the series encountered during its July 2023 visit to the circuit known as ‘The Temple of Speed’.

Designed for swift warmup, the Goodyear Racing Eagle Medium compound should give professional and amateur drivers alike the assurance to push hard immediately upon leaving the pit lane despite lower temperatures. The layout's long straights and tight chicanes echo Le Mans, and Goodyear engineers have leaned on prior experience at Spa-Francorchamps and Silverstone to ready for the colder weather. Every LMGT3 team will have a designated Goodyear track support engineer on hand to advise on setup and race strategy across the weekend.

Single-stint tyre strategies are expected to be popular, mirroring last month's 6 Hours of Barcelona. If rain falls, the wide transition window of both the slick and wet tyres could open up intriguing strategic options on a drying surface. Beyond closing the third LMGT3 season in WEC, the weekend marks the last appearance of the current Racing Eagle slick and wet tyres; from next season, LMGT3 cars in WEC and the European Le Mans Series will race on new-specification tyres containing 66 percent sustainable material.

Across the Atlantic, Goodyear Racing Eagles will also be in action this weekend in the NASCAR Championship Races at Homestead-Miami Speedway. In addition, the NHRA Mission Foods Drag Racing Series wraps up next weekend at Pomona Dragstrip.

Stephen Bickley, Goodyear Endurance Program Manager, said, “Monza presents an interesting challenge to round out a competitive WEC season, particularly with the cooler conditions we expect at this time of year. Getting tyres up to temperature quickly will be important, but the fast warmup characteristics of our Goodyear Racing Eagle Medium should give drivers the confidence they need from the start of each stint. This weekend is a significant milestone for Goodyear as we conclude three seasons with our current LMGT3 tyre specification. After last month’s 6 Hours of Barcelona, teams have started testing our new tyres, which we’re looking forward to seeing in racing action next year.”

Kuraray America, Inc. is commemorating 10 years of production at its Bayport facility, a milestone shaped by a workforce assembled from widely differing backgrounds. Since operations commenced in 2016, the site has drawn staff from the oil and gas sector, from other Kuraray America locations and from Kuraray Group operations in Singapore and Japan as expatriates. That blend of experience and perspective formed the groundwork on which the site was built.

Across its first decade, Bayport has delivered enduring value to the company and its customers, powered by employees who gave their time, passed on expertise, assisted colleagues and helped steer the site towards success. The occasion gains further meaning from its proximity to the Kuraray Group's 100th anniversary in June 2026.

Kuraray America thanked the employees and customers whose backing sustained Bayport through its opening decade and will remain crucial going forward. Jacqueline Unzueta received special mention for leading the anniversary event's coordination, while Hans Vandommele, Charles Neal, Nelson Rodriguez, Takehiro Kanno and Frank Taylor were also recognised in connection with the celebration. The company affirmed its commitment to carrying forward the teamwork, expertise and shared purpose that have characterised Bayport's first 10 years.

Reflecting on the site's growth and his own professional journey, Raymond Myska, Plant Manager at Kuraray America's Bayport site, said, "My own journey at Bayport began in 2017. I joined as Maintenance Manager, and in 2025, I had the privilege of stepping into the role of Plant Manager. Although I wasn't here when the doors first opened, I've had the opportunity to grow alongside this team, witness how far we've come and contribute to the success stories we're celebrating today."
