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 Goodyear Highway Hero Award is actively seeking nominations to honour the exceptional bravery of commercial truck drivers. The programme, now in its 42nd year, recognises those who perform courageous acts that extend far beyond their typical job responsibilities to aid others and enhance public safety on North American highways.

To qualify for consideration, a nominee must hold a current Commercial Driver's License and drive an eligible vehicle, which includes long-haul trucks, vocational and infrastructure trucks and non-lifesaving emergency vehicles with rim sizes exceeding 19 inches. The incident must have taken place within the United States or Canada during the 2025 calendar year while the driver was officially on duty.

The nomination period remains open until 31 January 2026. Submissions require a detailed account of the event and are made through Goodyear’s dedicated online portal. Following a review of all entries, a panel of judges will evaluate the approved nominations to select one winner and up to two finalists. The grand prize winner will receive a cash award and a ride aboard the Goodyear Blimp, while the finalists will also be granted monetary prizes. The recipient of the award will be officially announced in early 2026.

Joe Stuglis, Vice President, Commercial Sales North America, Goodyear, said, "Truck drivers are the unsung heroes of our roads and communities. For more than four decades, the Highway Hero Award has celebrated those who step up in critical moments to protect others. We're proud to continue this tradition and shine a spotlight on their inspiring stories."

The Indian Tyre Technical Advisory Committee (ITTAC) has made a proposal to Tyre Retreaders Education Association (TREA) for mandating certain standards that will improve the quality of retreads.

Speaking to Tyre Trends about the move, a source privy to the developments explained, “We have sought TREA’s views on mandating the retread standards and we are currently awaiting their formal response on the subject. Once an agreement is reached with TREA, a formal proposal will be submitted to BIS for consideration. At present, the retread sector is largely unorganised with more than 10,000 retreaders operating. Once the applicable standards are mandated, all retreaders will be required to comply with the relevant BIS standards and mark their products with the BIS certification marks.”

“Considering the large number of retreaders operating in the market, enforcing retread standards will be a significant challenge for BIS,” he added.

As per an ICRA report, the Indian retreaded market was valued between INR 580 billion and INR 600 billion with a cumulative annual growth rate of 7–9 percent between FY23-26. As the market continues its projected trajectory, quality and efficacy become paramount not only to bolster recognition and usage but also to make a name at the global level.

The documents that were accessed by Tyre Trends signal a major restructuring of test procedures and physical property norms across key retreading standards.

At the centre of the exercise is remarks from Central Institute of Road Transport (CIRT), supplemented by inputs from a major tread maker, covering four foundational BIS retread standards, namely IS 15725, IS 15753, IS 15524 and IS 9168.

TREA members are yet to assess proposed updates to the physical-property criteria for uncured rubber including tread, belt, undertread, base and cushion gum compounds.

The technical work on retread-casing standard IS 15704 represents the most sensitive part of the proposal. Furthermore, ITTAC has partially aligned Indian requirements with ECE R109, the European regulatory benchmark.

Key alignments include widening allowable outer-diameter growth for tyres with section widths above 305 millimetre, raising permissible deviation from two percent to 3.5 percent for high-aspect-ratio radial tyres and four percent for bias-ply constructions.

ITTAC also endorsed the addition of a one percent deviation allowance for snow tyres, consistent with R109 clause 7.1.5.2.

The recommendations in the proposal also contains inputs from Michelin Tyres. The company had proposed a full R109-based clause on minimum material thickness above the breaker for diagonal-ply casings.

ITTAC did not accept the full wording, arguing that IS 15704 already covers requirements for both radial and bias tyres, but acknowledged that the minimum 0.80 millimetre non-repair spot thickness must be explicitly stated to prevent accidental exposure of the belt package during buffing operations, informed the source.

Alluding to how these changes will be incorporated, he noted, “As far as process is concerned, like in case of new tyres, retreader will apply to BIS for getting the license. After reviewing the application, a BIS auditor will visit the retreading facility and collect samples for testing at BIS-authorised laboratories. The laboratories will conduct tests as specified in the standard and submit their reports to BIS. If the sample successfully meets all requirements, a license is issued to the retreader, allowing them to mark their retreaded tyres with the applicable ISI mark.”

India’s retreading sector now stands at a defining crossroads. The push by ITTAC to formalise and mandate BIS standards marks a decisive shift from a largely fragmented landscape to one governed by measurable, certifiable quality benchmarks.

For more than 10,000 retreaders, the transition will not be easy as compliance, auditing and testing will demand new investments, capabilities and mindsets.

Yet, this transformation also presents an unprecedented opportunity. Standardisation could elevate Indian retreads from a cost-driven alternative to a globally credible, technically assured product category.

As TREA prepares its response and BIS gears up for the next drafting phase, the onus now lies on industry players to embrace this moment. If executed well, the reforms could not only improve safety and performance but also position India as a competitive force in the international retreading arena.

Linglong Tire has recognised its top-performing global dealers at a five-day event in London, bringing together partners from several regions as the Chinese manufacturer seeks to strengthen its international distribution strategy.

Dealers from Australia, El Salvador, Egypt, Finland, Italy, Poland, Turkey and Uzbekistan were among those invited. The company said participants were selected for achieving the highest sales of Linglong Group products in the first half of 2025, covering its core Linglong range as well as regional brands such as Atlas Tires in Australia and Benchmark in Turkey.

The event included corporate and product briefings, during which Linglong awarded certificates to all attendees. Several dealers also presented their own business strategies, outlining how they position the brand in their respective markets. Linglong said the exchanges enabled participants to compare marketing approaches and share regional insights.

The programme concluded with a group visit to a Premier League match between Chelsea FC and Arsenal FC. Linglong is a global tyre partner of Chelsea and is represented on LED boards at all home games at Stamford Bridge.

Shandong Linglong Tire Co., founded in 1975, operates seven research centres and seven manufacturing bases, including facilities in Thailand and Serbia. The company employs more than 19,000 people and supplies tyres to over 200 vehicle-production sites worldwide. It retains a presence in original equipment supply for manufacturers including Volkswagen, Audi and BYD.

Linglong said it intends to continue evaluating potential sites for future overseas capacity as part of its long-term global expansion strategy.

European replacement tyre demand was broadly stable in the third quarter of 2025, although overall volumes remain weaker than last year as economic softness and rising imports continue to weigh on the market, according to new figures from Tyres Europe.

The industry association said sales across the consumer segment — which includes passenger cars, SUVs and light commercial vehicles — were flat in the quarter and down slightly in the first nine months of the year. Adam McCarthy, Secretary-General of Tyres Europe, said: “Tyre markets were generally stable in the third quarter of 2025, although demand in the Truck & Bus tyre segment remained weak. Data for the first three quarters shows tyre volumes generally lower than the same period in 2024.”

The data point to an ongoing shift in consumer purchasing patterns. Sales of summer car tyres declined, while demand for all-season and winter products continued to rise. McCarthy added that “demand for car tyres is clearly shifting from summer tyres toward all-season and winter products”.

Truck and bus tyres recorded a sharper downturn. Third-quarter declines followed similar weakness earlier in the year, reflecting subdued freight activity and stronger competition from imports. Year-to-date sales fell about 1 percent. McCarthy noted that the segment’s performance “reflect[s] subdued economic activity across the region and an increase in imported tyres”.

Agricultural tyre volumes remained well below pre-pandemic levels, though quarterly figures were broadly stable. Moto and scooter tyres showed modest growth.

The update highlights significant changes in the region’s import landscape. Imports of passenger car and light truck tyres into the EU27 and UK rose 10 percent in the first eight months of 2025, although growth slowed sharply after a strong end to 2024 and early 2025. China retained a dominant market share of more than 70 percent, but Vietnam’s exports expanded rapidly from a low base, exceeding volumes from India. Truck and bus tyre imports increased nearly 14 percent, with Thailand and Vietnam accounting for more than half of extra-European shipments. China lost share and fell to third place.

Underlying mobility trends also point to a mixed recovery in tyre usage. Miles travelled by light vehicles across Europe are expected to surpass pre-pandemic levels in 2025, but car mileage in Western Europe will not fully recover until 2026 or later, according to the analysis. Truck mileage remains closely tied to GDP growth but has lagged behind owing to efficiency gains, larger vehicles and structural shifts in the European economy.

The report also emphasised regulatory barriers that continue to affect the recycling sector. Tyres Europe and Recycling Europe repeated their call for harmonised EU-wide End-of-Waste criteria for rubber derived from end-of-life tyres. “Standardised End-of-Waste criteria will boost demand for high-quality secondary raw materials and reduce dependence on virgin resources,” said McCarthy.

Tyres Europe represents 13 manufacturers whose global sales account for 70 per cent of the worldwide tyre market and collectively operate more than 70 production sites and over 20 research centres in Europe. The sector supports almost 500,000 jobs across the EU.
