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.

Bridgestone has reported a significant shift in UK consumer sentiment regarding electric vehicles, with new data indicating a sharp rise in drivers who reject the technology. The tyre manufacturer's survey reveals that 26 percent of motorists now declare they will never purchase an EV, up from 17 percent in 2025, while only 16 percent plan to acquire one within the coming year.

Persistent operational anxieties continue to overshadow the market. Battery durability and replacement costs trouble 55 percent of respondents, half worry about charging expenses and 44 percent express unease over range limitations and high sticker prices.

Infrastructure inadequacies further compound hesitancy, as 43 percent feel public charging stations remain insufficient and 41 percent are deterred by prolonged recharging times. Despite these barriers, 53 percent anticipate purchasing an EV within five years, while seven percent remain undecided.

Bridgestone is reinforcing its commitment through 'EV Ready' tyres like the Turanza 6, engineered for efficiency, safety and wear life across electric and combustion vehicles. These innovations align with the company's E8 Commitment and Ecology pillar, advancing sustainable tyre technologies and mobility solutions.

Drew Chapman, North Region Consumer Sales Director at Bridgestone, said, "Electric vehicles are becoming an increasingly familiar sight on our roads, but our research shows that many drivers still have genuine questions and concerns about making the switch. While some of the barriers are gradually reducing, issues such as battery life, charging costs and infrastructure remain front of mind for many motorists. The industry has made significant progress, but it's clear there is still work to do in building confidence among consumers.

"Whether drivers are behind the wheel of an EV, hybrid or conventional vehicle, they want products they can trust. Our focus is on helping motorists get the very best from their vehicles today while supporting the mobility solutions of tomorrow."

Developed and administered by FTSE Russell, a London Stock Exchange Group subsidiary, these benchmarks serve distinct investment purposes. The FTSE4Good Series is widely utilised by international investors as a reference for responsible portfolios. Meanwhile, the two Japan-specific indexes, designed to highlight domestic firms with exemplary ESG performance, have been adopted by the Government Pension Investment Fund to steer its own sustainable asset allocation.

Under the corporate sustainability motto of caring for the future, Yokohama Rubber continues to integrate social problem-solving into core business operations, thereby generating shared value. This longstanding index qualification reflects the firm’s consistent commitment to transparent governance, environmental stewardship and social responsibility, reinforcing its strategic focus on long-term value creation through ethical business conduct.

Apollo Tyres Ltd has launched the Apollo Altrust Winter van tyre, a new addition to its commercial vehicle lineup engineered to deliver extended durability alongside reliable snow and wet-weather traction. Scheduled for European release in July 2026, this winter variant finalises the Altrust family, which already includes the popular summer and all-season iterations.

Developed entirely within Europe, the tyre achieves a top wet grip classification of ‘A’ and a noise rating of ‘B’ at 72 decibels. Offered in 15 size options across 15- to 17-inch rim diameters, the Altrust Winter is designed to accommodate a broad spectrum of vans and light commercial vehicles, including contemporary models such as the Ford Transit, Mercedes Sprinter and IVECO Daily.

Superior handling on snow, ice and rain-soaked roads stems from several engineering innovations. A multi-pitch tread pattern optimises block sizing and spacing for consistent performance, while three-dimensional sipes enhance road biting capability. Additionally, the centre and shoulder lateral grooves have been strategically configured for swift water dispersal, which bolsters wet grip and lessens aquaplaning risks.

For fleet operators, longevity and reduced wear are critical to lowering total cost of ownership. Apollo’s research division formulated a compound with a balanced polymer-and-filler mix to boost abrasion resistance and curb material degradation. Reinforced shoulder tie-bars preserve a stable contact patch under heavy use, promoting even tread wear and sustaining all-weather effectiveness over the tyre’s lifespan. Noise management was also prioritised, with careful tuning of pitch sequences and shoulder block bridges to minimise acoustic output.

Udyan Ghai, Group Head – Marketing, Apollo Tyres Ltd, said, “Our research and development team in Enschede, The Netherlands, spent over two years exploring the needs of van owners and users, creating a winter van tyre that delivers an optimal balance of performance and value. They focused on those attributes that matter most to fleet operators and van drivers: safety, durability and low operating costs. We know that wet-weather performance is becoming increasingly important for operators across Europe, so we are particularly pleased to see the tyre secure an A rating for wet grip.”

AI mobile data capture company Anyline has reported that approximately 15 percent of tyres inspected across United States during National Tire Safety Week, observed from 29 June to 5 July 2026, registered tread depths below the critical safety threshold of 3/32 of an inch. The analysis was derived from all professional-grade inspections conducted nationwide using the company’s TireBuddy application during that seven-day period.

Industry observers suggest the actual prevalence of unsafe tyres on American roads may be significantly higher, as motorists who voluntarily participate in inspection events typically exhibit greater safety awareness than the general driving population. This self-selection bias implies that the overall percentage of worn tyres among all vehicles likely exceeds the recorded figure.

The data emerges against a backdrop of approximately 11,000 annual tyre-related traffic incidents documented by the National Highway Traffic Safety Administration, many of which involve tyres that showed no prior visible warning signs. National Tire Safety Week was established as an educational initiative to address this gap, given that gradual tread wear remains one of the most easily preventable contributors to highway accidents yet often goes unnoticed by drivers.

On 2 July 2026, Giti Tire collaborated with Anyline to host a complimentary inspection event at its North American headquarters in Charlotte, North Carolina. Participants received an artificial intelligence-powered tread measurement via the TireBuddy app alongside a pressure check, with both metrics compiled into a single visual report. The U.S. Tire Manufacturers Association advises motorists to conduct such evaluations at least once every two months.

William Estupinan, Vice President – Technical Service, Giti Tire, said, “We believe tyre maintenance education is most effective when it's personal. Providing drivers with a tread scan and air pressure reading for their own tyres brings tyre maintenance messages to life in a way that's meaningful and actionable.”

Christoph Braunsberger, CEO, Anyline, said, “Road safety is built from small, routine decisions and few are overlooked as tyre condition. National Tire Safety Week brings that risk into focus and reminds drivers how much a simple check can reveal. Our role is behind the scenes: giving the technicians who carry out inspections a more accurate, consistent way to measure tread depth. Precision like that is what safer roads are built on.”
