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.

Michelin has introduced two new high-efficiency tyres – the MICHELIN Primacy ^{5 energy} and MICHELIN Pilot Sport ^{5 energy}. These two new product families have been developed in direct response to the shifting requirements of contemporary vehicle design. With the automotive industry’s rapid transition toward electrification, manufacturers are increasingly demanding tyres that deliver an exacting balance of low rolling resistance, tenacious grip, extended durability and precise handling dynamics. Both new ranges have been engineered to fulfil these criteria, offering tangible benefits such as extended range for electric vehicles and reduced fuel consumption for internal combustion models, all while upholding uncompromising standards of safety and longevity.

The MICHELIN Primacy ^{5 energy} is distinguished by its triple A-rating for wet braking, rolling resistance and external rolling noise. Compared to its predecessor, it achieves wet braking distances that are up to eight percent shorter, both when the tyre is new and when worn down to two millimetres of tread depth. Its best-in-class longevity is enabled by Energy Passive 2.0 Technology, which employs functionalised elastomers, advanced resins and a refined architecture to deliver the highest mileage in its European segment, including on electric vehicles. Independent tests have shown it can outlast leading competitors by as much as 40 percent in comparable conditions. The efficiency gains are substantial, offering up to six percent lower fuel consumption, which translates to roughly 0.3 litres saved per 100 kilometres, along with a 10 percent increase in electric vehicle range. These figures mean substantial fuel savings and a 327 kg reduction in CO₂ emissions over the tyre’s lifespan.

The MICHELIN Pilot Sport ^{5 energy} merges motorsport-derived engineering with energy-conscious design. Leveraging Dynamic Response Technology and a new Adaptive Grip Compound, it delivers the precise steering feedback and superior wet and dry grip expected from a high-performance tyre. MaxTouch Technology addresses the historically rapid wear associated with performance vehicles by optimising the contact patch for even wear distribution, while an Energy Passive compound in the shoulder areas achieves an unprecedented level of rolling resistance for this category. The result is a sport tyre that not only significantly outperforms key rivals in longevity tests but also secures an A rating for rolling resistance. Its endurance credentials were validated during the MERCEDES AMG GT CONCEPT XX world record, where it sustained a constant speed of 300 kmph for nearly eight days, demonstrating exceptional durability and energy efficiency under extreme conditions.

Both ranges are now being rolled out with a clear focus on meeting the specific demands of modern mobility. The Primacy ^{5 energy} is initially available in 33 sizes spanning 16 to 19 inches, while the Pilot Sport ^{5 energy} launches with 19 sizes across 19 to 21 inches. By addressing the dual imperatives of enhanced performance and reduced environmental impact, Michelin aims to reinforce its position in a segment that continues to dominate global tyre sales, offering solutions that cater equally to the needs of electric vehicles, hybrids and traditional internal combustion engine cars.

Jean-Claude Pats, Automobile and Two-Wheel Business Line Director and member of Michelin’s Executive Committee, said, “These innovations reflect a profound transformation in mobility. Today’s tyres must combine performance, longevity and energy efficiency while supporting the transition to electrified vehicles. With MICHELIN Primacy ^{5 energy} and MICHELIN Pilot Sport ^{5 energy}, drivers and manufacturers no longer need to compromise between performance, safety, durability and efficiency. These new ranges demonstrate Michelin’s continued investment in innovation and our ambition to deliver technologies that support the mobility needs of today and tomorrow.”

The ZARE initiative held its 2026 partner meeting on 18 March 2026 in Schwenningen, hosted by the Bavarian used tyre disposal company Reifen Draws, which was simultaneously celebrating its 50th anniversary. Guests were given a firsthand look at the company’s modern recycling operations. For five decades, Reifen Draws has served tyre retailers, car dealerships and repair shops across a 200-kilometre radius, earning a reputation for reliable service and expert advice as a certified disposal firm.

During the meeting, partners described a strained market environment marked by declining business volumes, mounting price pressure and a growing shift towards lower-value scrap. Rising fuel costs add further strain, as these expenses can only be partially passed on. The situation underscores that maintaining stable, high-quality tyre recycling remains a persistent challenge requiring coordinated effort across the entire value chain.

On the political front, partners welcomed developments at the state level, notably the integration of used tyres into North Rhine-Westphalia’s circular economy strategy following an industry roundtable. However, ongoing discussions highlight the need to strengthen recycling markets and improve regulatory frameworks. In this context, a recent call by the European Court of Auditors to reinforce recycling markets – emphasising functioning markets, consistent implementation and reliable EU financing – was noted. The rise in export inquiries from non-OECD countries further reinforces the importance of transparent material flows and clear rules for a sustainable circular economy.

A notable highlight was a presentation by detection-X GmbH on automated tyre damage detection and sorting. A pilot project on damage analysis is already underway with one ZARE partner, aimed at enhancing process efficiency and recycling quality – a significant step towards a more effective circular economy.

For the coming year, the partners have prioritised a joint presence at THE TIRE COLOGNE trade fair, along with refining tendering standards, addressing declining online inquiries and strengthening public outreach. These efforts seek to raise the visibility of certified used tyre disposal and underscore the value of high-quality recycling.

Looking ahead, the new Waste Shipment Regulation, taking effect in May 2026 and becoming mandatory in 2027, will introduce significant organisational and documentation demands affecting international material flows. ZARE partners intend to actively incorporate this topic into relevant industry events.

Overall, the 2026 partner meeting reaffirmed that while the industry faces considerable challenges, it benefits from strong networks, innovative capacity and a clear sense of purpose. In a demanding market environment, close collaboration remains essential as the ZARE partners continue advancing sustainable, high-quality solutions for end-of-life tyres across the entire value chain.

Toyo Tire Holdings of Americas Inc., the parent organisation of Toyo Tire U.S.A. Corp. and Nitto Tire U.S.A. Inc., has officially inaugurated a new tyre warehouse in Shippensburg, Pennsylvania. This facility is scheduled to commence its initial outbound shipping operations on 1 April 2026, marking a significant step in the company’s efforts to strengthen its presence in the Northeast and Mid-Atlantic regions. The strategic development of this warehouse directly supports the corporation’s midterm expansion objectives while aiming to reduce service times for key dealers and customers throughout that part of the country.

Spanning 409,500 square feet, this distribution hub offers storage capacity for as many as 368,000 tyres. Its primary purpose is to elevate service and distribution capabilities across 14 states in the Northeast and Mid-Atlantic, creating a ripple effect that allows the company’s existing tyre warehouses to operate with greater efficiency and maintain more consistent stock levels. By alleviating pressure on other locations, the new facility helps streamline the broader supply chain network, ensuring that inventory is positioned to meet regional demand more responsively.

In addition to its regional distribution role, the Shippensburg location is set to receive product directly from Toyo’s manufacturing facility in Serbia via the Port of New York and New Jersey. Plans are already in place to convert the site into a Foreign Trade Zone during the latter half of the year, a move intended to facilitate winter delivery operations for Toyo Canada. Equipped with advanced technology tailored specifically for tyre storage, this new warehouse represents the fifth tyre production warehouse and distribution centre established by the company across the continental United States, further solidifying its logistical infrastructure.

Curtis Maggard, Chief Supply Chain Officer, Logistics, said, “This warehouse represents a significant investment by Toyo, providing improved supply and faster service levels to our valued customers in the region. The warehouse is designed specifically for high volume tyre storage and will support Toyo’s sales forecast.”
