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.

Indian manufacturer invests in radial tyre capacity and electric vehicle products as it seeks growth in domestic and export markets

JK Tyre and Industries is expanding production capacity and pushing into higher-value tyres as the Indian manufacturer seeks to capitalise on strong vehicle demand, the shift towards premium cars and the growth of electric mobility.

The company plans to invest in additional truck and bus radial and passenger car radial capacity, while broadening its distribution network and developing products for overseas markets. The strategy comes as a sharp increase in raw-material prices threatens to erode the benefits of rising sales.

Nearly 30 percent of JK Tyre’s passenger car tyre volumes in the first half of the financial year came from premium products with wheel sizes of 16 inches and above, Managing Director Anshuman Singhania told analysts on the company’s second-quarter earnings call. The segment has grown at an annual rate of about 20 percent over the past two to three years.

The shift towards larger tyres reflects changing consumer preferences in India’s car market, where manufacturers are increasingly catering to buyers seeking more premium vehicles. JK Tyre is seeking to capture that demand while maintaining its position in commercial vehicle and agricultural tyres.

Electric mobility and premium products

Electric mobility is another area of growth. The company said its electric vehicle tyre volumes rose by more than 24 pe cent quarter on quarter. It also highlighted its position in electric trucks and buses, and said the MG Hector Tomahawk had been launched with its Ranger HPE electric vehicle-specific tyres.

JK Tyre is investing in research and development and using artificial intelligence and machine learning in product design, manufacturing and supply-chain management. The company is also expanding its range of specialist off-the-road tyres, targeting applications where product performance and specifications are important purchasing considerations.

Expanding distribution

The push into premium products is accompanied by an effort to widen the company’s reach among customers. During the second quarter, JK Tyre added more than 250 pit shops and more than 80 dealers and distributors, almost half of the latter in rural markets. It also expanded its fleet accounts.

The replacement market, in which vehicle owners buy tyres independently of new vehicle purchases, accounted for about 60 percent of standalone revenue.

Demand remained strong across several categories. Truck and bus radial tyre volumes supplied to original equipment manufacturers increased 76 percent year on year, while passenger car radial volumes rose 14 percent. Farm tyre demand also grew, although management warned that uneven rainfall in some agricultural regions could weigh on the farming season.

JK Tyre expects demand to remain healthy in the second half of the financial year, supported by infrastructure spending, freight movement and vehicle manufacturers’ year-end purchasing. It expects high-single-digit growth in the truck and bus replacement market and mid-single-digit growth in passenger car tyres over the medium term.

Raw-material inflation

The outlook is less straightforward on costs. Raw-material prices have risen by about 30 percent over the past six months, according to management, amid supply-chain disruption and geopolitical tensions linked to the conflict in West Asia. The company expects a further increase of 4–5 per cent in its raw-material cost basket in the third quarter.

JK Tyre plans to raise selling prices by a similar amount, but acknowledged that passing on higher costs is difficult in the replacement market, where customers are sensitive to price. Price increases under contracts with vehicle manufacturers are partly linked to input-cost indices, but take time to feed through.

The company is relying on higher selling prices, a more favourable product mix and cost efficiencies to protect profitability. Its ability to do so will be tested if commodity inflation persists.

Capacity and export plans

Capacity expansion is central to the growth strategy. JK Tyre said projects worth about INR 13 billion covering truck and bus radial and passenger car radial tyres were under implementation, following the completion of projects worth INR 14 billion. Utilisation at its Indian plants was above 90 percent across key segments, leaving the company looking to add capacity to meet demand.

JK Tyre is also looking overseas for growth. The company is assessing opportunities arising from the India-UK free trade agreement and has developed products specifically for European markets. Management said it was already supplying some European markets, but did not confirm any material increase in UK orders or shipments following the trade agreement.

Exports from India rose 14 percent sequentially in the second quarter.

Mexican subsidiary recovers

Its Mexican subsidiary, JK Tornel, is meanwhile continuing a recovery programme focused on operational efficiency, quality and modernisation. Management expects sales to move towards levels comparable with the previous year in the third and fourth quarters. It also reported triple-digit growth in shipments from Mexico to the US on a quarter-on-quarter basis, against a backdrop of uncertainty over US trade policy and the review of the United States-Mexico-Canada Agreement.

Bridgestone has unveiled a new generation of aircraft tyres designed for the Boeing 737, delivering improved wear performance through optimised design. The tyres were first introduced on aircraft flown by partner airlines, helping to enhance their operational efficiency, and the company now intends to extend their availability to carriers worldwide. From 2027, tyres incorporating the advanced technology are scheduled to be fitted to a broad range of aircraft.

The launch comes as aviation continues to recover rapidly from the Covid-19 pandemic, a rebound that has brought labour shortages and made operational efficiency more critical than ever. At the same time, the sector is stepping up sustainability efforts in support of the International Civil Aviation Organization's target of net-zero CO2 emissions by 2050. Bridgestone refined the technology using extensive flight data supplied by partner airlines together with its own simulation tools, carrying out thorough evaluations and verification across a wide range of conditions.

The new tyres preserve the high durability of the company's existing Revolutionarily Reinforced Radial (RRR) technology while markedly improving wear resistance and curbing uneven wear through a new tread compound and an optimised contact profile. Casing durability has also been strengthened via an optimised sidewall design. Combined with advanced tyre wear prediction solutions developed alongside airlines and with retreading, the tyres support greater operational efficiency and lower CO2 emissions without compromising safety or reliability.

The new compound, which improves carbon black reinforcement and dispersion through Bridgestone's proprietary NanoPro-Tech molecular control technology, delivers better wear balance during landing and taxiing. Compared with the previous product, the tyre achieves more than 20 percent additional landings per tyre, reducing replacement downtime and maximising aircraft utilisation for high-frequency operators such as domestic carriers, while helping to lower operating costs.

Separately, the combination of flight data and simulation enabled Bridgestone to optimise contact conditions for aircraft-specific surfaces, including runways and taxiways, producing more uniform contact and cutting irregular wear seen on certain routes by more than 20 percent. This lowers the risk of unplanned replacements and flight delays, supporting on-time performance and easing the burden on maintenance teams. Further optimisation of the sidewall design based on RRR technology has extended tyre durability, and because roughly 80 percent of the materials in a retreaded tyre can be reused from the original, retreading reduces CO2 emissions at the manufacturing stage.

Bridgestone's aircraft tyres hold the leading installation share among airlines ranked in the top 10 of the SKYTRAX World Airline Awards 2025, underpinning safe and reliable operations. The company aims to maximise the productivity and economic value of airline operations, in line with the ‘Extension’ and ‘Economy’ commitments set out in the Bridgestone E8 Commitment, while enabling longer tyre life with lower resource consumption and emissions.
