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.

Titan International, Inc., a leading global manufacturer of off-highway wheels, tyres, assemblies and undercarriage products, has announced a decision to consolidate its North American manufacturing footprint.

Hankook Tire faces a demanding technical assignment at Round 6 of ABB FIA Formula E World Championship Season 12 as the series descends on Madrid for the first time. The occasion is the 2026 CUPRA Raval Madrid E-Prix, scheduled for 21 March 2026 at the Circuito del Jarama, a storied permanent circuit situated just north of the Spanish capital. Jarama first acquainted itself with the series during pre-season testing in the previous season and now assumes its place as an official race venue. Stretching to 3.934 kilometres with 14 turns, it immediately distinguishes itself as the longest circuit in Formula E history, surpassing any previous track by roughly 400 metres. Its blend of fast, flowing corners and short straights places relentless emphasis on energy management and regenerative braking while simultaneously challenging the grip and thermal resilience of Hankook’s iON Race tyre.

Strategic complexity intensifies at this round with the introduction of PIT BOOST in a single-header setting for the first time since the mechanism debuted in Season 11. Drivers will be obliged to make a pit stop that replenishes the battery with an additional 10 percent energy in approximately 30 seconds. ATTACK MODE will also be available once, lasting six minutes. When coupled with an extended race distance of 23 laps, these factors shift the spotlight squarely onto tyre consistency and energy strategy across the entirety of the event.

From a technical perspective, Jarama imposes a distinctive set of demands that Hankook must navigate carefully. Although teams accumulated initial data during pre-season running at the same circuit in the prior season, March conditions for the race weekend could bring different ambient temperatures and evolving track surface characteristics. The layout subjects the tyres to sustained stress through rapid directional shifts and high cornering loads, making predictable warm-up behaviour, controlled thermal response and stable traction indispensable for both qualifying pace and race efficiency.

The race weekend schedule begins with Free Practice 1 on 20 March, continuing through Saturday’s race on 21 March. A Formula E Rookie Test will follow on 22 March, offering development drivers valuable track time at Jarama.

Manfred Sandbichler, Senior Director of Hankook Motorsport, said, “Madrid represents exactly the kind of challenge that tests every aspect of tyre performance. Jarama’s combination of high-speed corners and limited straight sections, together with the introduction of Pit Boost, creates a unique race dynamic. With teams working from a limited data baseline, the iON Race tyre is designed to deliver consistent grip and stable thermal performance across a wide operating window, supporting competitive and closely fought racing.”
