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.

Pirelli has created bespoke versions of its P Zero R tyre for the new Audi RS 5 and the RS 3 competition limited, aiming to deliver everyday driving pleasure without sacrificing track capability. Special emphasis is placed on superior grip and shorter braking distances. Drawing on over 25 years of collaboration with Audi Sport, these fitments reflect experience gained from developing tyres for high-performance SUVs and the sportiest sedans.

Audi’s main target was braking performance, and the P Zero R was engineered to approach Pirelli’s semi slick Trofeo R. This results in extremely short stopping distances with rapid deceleration even under demanding conditions. Pirelli’s German R&D centre worked with Milan headquarters on a new compound that performs well even when cold, responding to Audi’s request for safety during deceleration. Though nearing track-oriented products, the P Zero R remains suitable for daily use.

The RS 3 competition limited celebrates 50 years of the five-cylinder engine. Two tyre options are available: the standard P Zero R provides strong grip on dry and wet roads, while the P Zero Trofeo R semi slick is designed mainly for track driving. Its motorsport derived rubber delivers exceptionally high dry grip, stability and short braking distances. Development used digital simulation at both companies, with physical tests later validating data on circuits like the Nürburgring Nordschleife.

The Audi RS 5, the brand’s first high-performance plug-in hybrid, required a new High Load tyre size. Pirelli reinforced the P Zero R’s structure to handle the hybrid components’ extra weight while maintaining driving precision. This partnership, symbolised by the R0 marking, began with the original RS 4 25 years ago and continues with record setting Nürburgring performances in 2024 by the RS 3 with Trofeo R and the RS Q8 performance with P Zero.

Steffen Bamberger, Head of Technical Development at Audi Sport GmbH, said, “The tyre is the only connection between the vehicle and the road surface. Therefore, it plays a significant role in chassis development, especially in our RS models, where excellent handling has paramount importance. Plus, a close, collaborative partnership is essential to achieving this level of performance.”

TYRESYSTEM, functioning as the digital arm of AZuR partner RSU, has made Tyre Pressure Monitoring System (TPMS) its central pillar of expertise. This unit moves beyond simple product sales by offering specialised training focused on tyre pressure monitoring systems. Their inventory is substantial, featuring over 500 sensors designed to accommodate a wide spectrum of vehicle types, and this hardware is supported by complementary valves, service kits and diagnostic programming tools.

The importance of this focus became legally binding on 1 November 2014, when TPMS became mandatory for cars, motorhomes and off-road vehicles. For workshop operators, a neglected sensor is a serious liability, as it not only creates a safety hazard but also guarantees a failed roadworthiness test like the TÜV. Consequently, the seasonal tyre change has evolved into a critical checkpoint where technicians must rigorously inspect sensor batteries and overall condition to ensure compliance.

To address this industry need, TYRESYSTEM acts as a holistic online wholesaler for tyres, rims and complete wheels. Recognising that hardware alone is insufficient, they established the TyreSystem Academy to deliver practical TPMS training through both online and on-site courses. This educational push helps workshops master modern tyre complexity. Correctly maintained TPMS systems preserve optimal pressure, reduce tread wear and extend tyre life, directly supporting resource conservation and a functioning tyre circular economy within the AZuR network.

Parcours, a British wheel brand specialising in aerodynamic, wind-tunnel-tested carbon wheelsets for road, gravel and triathlon cycling, has launched the Strade GT, the debut model in its new GT Series. At the heart of this wheelset lies VibraCORE, a technology developed alongside Lineat and Nottingham Trent University. VibraCORE embeds Lineat’s reclaimed aligned carbon fibre material, known as AFFT, directly into the rim’s spoke bed. This structural integration reduces vibration at its source rather than simply damping it after transmission begins.

The principle behind VibraCORE is straightforward: less vibration reaching the rider means less fatigue, allowing for longer, faster rides. Not all vibrations affect the body equally. Certain frequencies are either amplified by the human body or directly contribute to muscle exhaustion. VibraCORE targets these specific ranges, absorbing and dissipating vibrational energy before it travels through the wheelset to the rider. This approach directly addresses the harsh, high-frequency ‘road buzz’ that makes rough roads particularly draining.

In practical testing at standard road tyre pressures, VibraCORE reduces root mean square vibrational energy by an amount equivalent to lowering tyre pressure by roughly 10 to 15 psi. Crucially, this benefit comes without the usual penalties of softer tyres, such as reduced rolling efficiency or compromised handling precision. As a result, the Strade GT delivers a calmer, more controlled ride over long distances while retaining the stiffness, responsiveness and aerodynamic performance expected from a high-end wheelset.

To verify these claims, Parcours partnered again with Nottingham Trent University for controlled real‑world testing across multiple riders and surfaces. Using vibration sensors and frequency domain analysis based on power spectral density, the data showed that rims with VibraCORE reduced vibration energy by 19 to 23 percent compared to identical rims without the technology. This translates directly into a noticeably smoother ride on rough terrain and lower cumulative fatigue over extended rides.

Beyond comfort, the Strade GT represents an evolution of Parcours’ existing Strade platform. Its rim profile is optimised around a 30‑mm tyre, outperforming the previous model by 3.2W at 48 kmph, improving handling stability by 15 percent and achieving a weight of just 1,130g. VibraCORE also enables the use of lightweight Alpina Carbolite carbon spokes. Although sustainability is not the primary goal, the technology incorporates recycled carbon from Lineat’s AFFT process. Parcours is now developing a full circular pathway so that carbon recovered from old wheels, including those from its Crash Replacement Programme, can be reprocessed into VibraCORE components for future wheelsets. In this way, the Strade GT proves that speed and comfort need not be opposing forces.

Continental is celebrating two decades of its Camaçari tyre factory, situated near Salvador in Brazil. This occasion represents a major milestone for the firm’s operations throughout the Americas, as the site has served as a trusted partner across South America since its April 2006 opening. The facility supplies both replacement tyres and original equipment manufacturers with high-grade products for passenger cars and commercial vehicles.

Approximately 136 million tyres have rolled off the line at Camaçari over the last 20 years. Roughly BRL 1.2 billion (approximately EUR 235 million), has been invested there in the past 10 years alone to sharpen competitiveness through better efficiency, product quality and responsiveness to customers. The factory currently provides jobs for around 2,000 people, making it a leading industrial employer locally, with its future success built on team spirit, consistent quality and a strong customer focus.

The site began as a greenfield project in 2004 and was formally inaugurated in April 2006, with the first tyre, a ContiEcoContact 3, produced five months earlier in November 2005. Today, the factory supplies original equipment to major automotive names including General Motors, Volkswagen, Renault, Honda, Fiat and Mercedes‑Benz, proving its dependable and uniform product standards. This same drive for steady improvement supports the plant’s role in Continental’s wider environmental goals.

By constantly tracking energy use and managing it responsibly, the Camaçari plant ensures that all power generated or consumed on site is used as efficiently as possible. The facility relies entirely on LED lighting, which saves more energy than conventional options, and has carried out targeted production upgrades such as better insulation on critical machinery. These efforts have yielded annual energy savings, including a total cut of 10.4 gigawatt‑hours in 2025, equal to about five percent of the plant’s yearly energy consumption.

Shander Basílio, plant manager of the Continental tyre plant in Camaçari, said, "Our 20-year journey in Camaçari is a story of continuous growth, operational excellence and the deep commitment of our people to this region. I would like to sincerely thank all our employees for their outstanding contribution as well as to our customers for their continued trust. Looking ahead, we are dedicated to writing the next chapter of our plant’s success.”

Rodrigo Bonilha, head of Continental Tires South America, said, “I would like to congratulate our manufacturing team in Camaçari on their 20th anniversary. The production facility is a key asset for our business in the region. By manufacturing premium tires locally, we ensure a reliable supply for the Brazilian market while securing valuable local jobs. This ‘in the market, for the market’ approach is fundamental to how we deliver consistent product quality and performance for customers and consumers.”
