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 has entered a new partnership with Staffordshire Police, reinforcing a joint commitment to improve road safety and reduce fatalities and serious injuries across the county. The collaboration aims to highlight the critical role tyres play in protecting road users by encouraging simple, regular checks of pressure, tread depth and overall condition.

The value of this preventative approach was recently demonstrated during a multi-agency enforcement operation at the DVSA Vehicle Inspection Site in Doxey. Held on 25 August, Operation Doxey involved Staffordshire Police, West Mercia Police, DVSA, Datatag, the Forensic Collision Investigation Unit and TyreSafe. Inspectors directed 30 vehicles into the site, covering leisure vehicles, towing vehicles, light commercial vehicles and goods vehicles.

Seven tyre and wheel-related defects, mechanical risks and pressure discrepancies were identified. These included a tyre cut through to the cord, which received an immediate prohibition notice, a tyre running roughly 30 percent below recommended pressure, an overweight light commercial vehicle with a nail embedded in a tyre and all four tyres underinflated, a significant rear axle pressure imbalance, a missing wheel nut and an 11-year-old tyre. Leisure vehicle owners generally showed good tread awareness, though pressure maintenance remained an issue, while commercial vehicles presented several preventable defects.

Staffordshire has one of UK’s statistically safest road networks, yet serious collisions remain a concern, particularly on single carriageways. Rural bends, changing speed limits and limited visibility add risk, while motorcyclists and vulnerable road users are disproportionately affected. Common factors include failing to look properly, misjudging speed or path and driving too fast or carelessly. TyreSafe now works with over 260 organisations, and this partnership encourages Staffordshire motorists to make tyre checks routine.

Stuart Lovatt, Chairman, TyreSafe, said, “We are delighted to welcome Staffordshire Police as a TyreSafe partner. While Staffordshire has a strong road safety record, every serious collision has potentially devastating consequences for those involved, their families and their communities. The recent Operation Doxey enforcement activity demonstrates exactly why preventative vehicle maintenance matters. Across just 30 vehicles, inspectors identified a number of serious tyre and wheel defects, including a tyre cut to the cord, significantly incorrect tyre pressures, an embedded nail, a missing wheel nut and a tyre that was 11 years old.

“These findings are a powerful reminder that problems are not always obvious from behind the wheel. Simple checks before a journey can help identify issues before they become a danger on the road. Different roads present different challenges, particularly rural and single carriageway roads where the consequences of losing control or being unable to stop safely can be especially severe. Road safety requires a collective effort, and partnerships such as this are incredibly important. By combining the reach and expertise of Staffordshire Police with TyreSafe’s specialist knowledge and campaigns, we can help more road users understand the simple but crucial role their tyres play in keeping themselves and others safe.”

Police Sergeant Adam Van de Sande, Staffordshire Road Crime – Proactive & Harm Reduction Team, said, “Keeping people safe on Staffordshire’s roads requires everyone to play their part. We are committed to working with partners to reduce the number of people killed and seriously injured on our road network. Operation Doxey demonstrated the value of partnership working, with officers, vehicle examiners and road safety specialists able to identify a range of defects and safety issues before those vehicles continued their journeys.

“Vehicle safety is an important part of that responsibility, and tyres are fundamental to a vehicle’s ability to stop, steer and maintain grip. We are pleased to be working with TyreSafe to raise awareness and encourage motorists to make regular tyre checks part of their routine vehicle maintenance. Our message to road users is simple: don’t wait for something to go wrong. Take a few minutes to check your vehicle and make sure it is ready for the road.”

The AZuR Network has been honoured with the German Award for Sustainability Projects 2026 in the C2C/Recycling category for its ‘Retreading: Climate Protection on Wheels’ project. The recognition highlights the network's efforts to expand tyre retreading across Germany and Europe, thereby extending the useful life of tyres. Retreading works by reusing a suitable used tyre casing and applying a fresh tread, keeping a substantial share of the original tyre in circulation.

A life cycle assessment commissioned by AZuR and carried out by the Fraunhofer Institute UMSICHT compared retreaded tyres with equivalent new ones. Under the conditions examined, producing a retreaded truck tyre generated roughly 135 kilogrammes less greenhouse gas emissions, a reduction exceeding 60 percent. The process also reuses considerable portions of the existing tyre casing, reinforcing its environmental advantages.

The jury underscored the project's scalability and its relevance to the industry. Official documentation further noted the political integration of the topic as a key strength, with the EU taxonomy confirmation in 2025 representing a tangible milestone. The award places AZuR among well-known companies and innovative projects, including a climate protection cooker initiative in Cameroon, a capsule-free coffee system and a mental health awareness campaign.

Knauf secured first place in the same category with its circular gypsum supply chain, while Schmitz Cargobull led the Mobility and Logistics Solutions category. Other first-place winners included DEKRA, Hansgrohe, Pfleiderer Germany and SBRS. Presented by DISQ with ntv and DUP UNTERNEHMER under Brigitte Zypries' patronage, the 2026 edition saw 433 nominations, with 46 organisations recognised across 19 categories on 17 September in Berlin.

Christina Guth, Network Coordinator, AZuR, said, “This award belongs to our entire network. Retreading only works when many stakeholders collaborate along the value chain – from certified end-of-life tyre recyclers, tyre manufacturers and retreaders to retailers and fleet operators, all the way to academia. The award highlights the potential of using high-quality tyres for longer and keeping their casings in circulation.”
