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.

TyreSafe, UK’s leading tyre safety charity, has launched its annual Tyre Safety Month by cautioning UK motorists that confidence in their vehicles’ stopping ability may be misplaced. Research indicates that although 83 percent of drivers feel fully in control of stopping distances, merely 6 percent know the additional distance required to halt in wet conditions at motorway speeds.

The study reveals that 94 percent of drivers underestimate how sharply stopping distances grow in rain, with many erring by substantial margins. This mismatch between perceived and actual risk spans every UK region, pointing to a nationwide problem involving driver awareness and vehicle preparedness.

In response, TyreSafe advises routine tyre checks, especially before seasonal shifts and heavier rainfall. Motorists are urged to remember the ACT principle – air pressure, condition and tread depth – and to act before they react.

Stuart Lovatt, Chairman, TyreSafe, said, “Many drivers and riders believe they are in control – but that confidence is often misplaced. Stopping distances in wet conditions can be far greater than expected, and tyres play a critical role in that equation. If your tyres are not properly maintained, your ability to stop safely is significantly reduced – no matter how confident you feel behind the wheel.”

Scandinavian Enviro Systems AB (publ) has secured a second extension of its company reorganisation, with the Gothenburg District Court approving a further three-month period lasting until 27 November 2026. The company has been under reorganisation since 27 February 2026, when the court initially granted the process. An earlier extension had already pushed the deadline to 27 August 2026 before this latest decision.

In its ruling, the District Court noted that Enviro has submitted a draft reconstruction plan and secured the necessary financing for it. The court also found that the company has taken other required measures, leading it to conclude that exceptional grounds exist to justify continuing the reorganisation beyond the ordinary timeframe.

Enviro now plans to ask the court to order plan negotiations and schedule a plan hearing as soon as possible. At that hearing, affected parties will be placed into groups and permitted to vote on whether to adopt the reorganisation plan. Details of the hearing date and participation instructions will be announced via press release and the company's website. Unless plan negotiations are ordered earlier, a reorganisation may last at most one year, or 15 months from the initial decision in such cases.

Fredrik Aaben, CEO, Enviro, said, "The District Court's decision gives us the opportunity to continue the intensive work of completing the company reorganisation. We have taken several important steps forward and are now working purposefully to establish a strong and long-term sustainable Scandinavian Enviro Systems. The strong interest in Enviro's technology persists, both with regard to licensing and other forms of collaboration. We are firmly committed to completing the reorganisation and building a strong industrial company based on our world-leading technology.”

Continental has launched the Conti HSR 5 EP steer tyre and Conti HDR 5 EP drive tyre, expanding its Generation 5 regional haul lineup. Engineered for regional fleet operations, both products target greater mileage, better fuel economy and longer casing life, aiming to lower fleets’ total cost of ownership.

The tyres suit routes marked by frequent stops and starts, urban and suburban travel and changing road surfaces. Their advanced tread patterns and latest compound technology seek a balance among wear performance, rolling resistance and retreadability while supporting year-round operation.

For the steer position, the Conti HSR 5 EP uses a new five-rib tread pattern and optimised footprint to improve wear and promote even treadwear. With Continental’s Generation 5 compound, it offers an estimated 22 percent mileage gain over its predecessor while keeping rolling resistance low for fuel efficiency.

The Conti HDR 5 EP drive tyre combines an open shoulder design, enhanced stone-trapping resistance and better cut-and-chip protection to preserve casing integrity and retread potential. It delivers an estimated 19 percent removal mileage improvement over its predecessor while maintaining fuel-saving rolling resistance. Both tyres are available from October 2026 in key regional haul sizes, with more sizes planned during 2027.

Shaun Uys, Vice President Marketing and Sales, Truck Tires US, said, "Regional fleets continue to face mounting pressure to improve operating efficiency while controlling costs. The new Conti HSR 5 EP and Conti HDR 5 EP were developed to help fleets go farther on every tyre investment through increased removal mileage, lower fuel consumption and enhanced casing life."
