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.

The Tire and Rubber Association of Canada (TRAC) has released a new Probe Research survey showing that high gasoline prices are dramatically altering Canadian driving habits this summer. Two-thirds of motorists say fuel costs will force them to cancel or shorten road trips, yet 81 percent still plan at least one day trip or overnight stay. Seventy percent of respondents believe expensive fuel is the new normal rather than a temporary fluctuation.

Travel patterns are turning inward, with more Canadians opting to remain close to home. More than two-thirds have no plans for a United States road trip in 2026, while over half had already scrapped cross-border travel last year. Only one in ten drivers expects to head south of the border by car this year, marking a sharp retreat from international driving.

A significant disconnect exists between Canadian drivers’ tyre maintenance knowledge and their daily habits. Most understand that proper inflation boosts fuel efficiency, extends tyre life, prevents blowouts and improves handling. However, regular pressure checks remain uncommon. While 93 percent agree proper inflation is vital for safety and 85 percent know it saves fuel, only 35 percent of those with digital pressure displays check their tyres routinely. Among drivers without such displays, a mere 16 percent follow the monthly check recommendation.

Technical misunderstandings are widespread. Two-thirds of drivers do not know that pressure must be measured when tyres are cold. Nearly three in ten mistakenly use the sidewall stamp, which lists maximum load pressure rather than the recommended level, leading to uneven wear and reduced traction. Eleven percent rely on visual inspections or admit ignorance about proper inflation, even though a tyre can be underinflated by 20 percent or more and appear normal.

Using Statistics Canada data showing 43.8 billion litres of gasoline purchased in 2024, TRAC calculated substantial potential savings. United States Department of Energy studies indicate proper inflation improves fuel economy by 0.6 percent on average. Applied nationally, that would save 262.8 million litres of fuel annually, preventing over 600,000 metric tonnes of CO₂ emissions. At April 2026 fuel prices of 1.69 dollars per litre, those savings translate to approximately 444 million dollars. Tyre manufacturers are also developing low rolling resistance tyres with specialised tread patterns and lighter materials, which can improve fuel economy by two to four percent, saving hundreds of dollars over a tyre’s lifespan.

The online survey of 1,000 Canadian drivers was conducted between 6 and 14 April 2026, using a national panel. A probability sample of this size would yield a margin of error of plus or minus 3.1 percentage points, 19 times out of 20.

Carol Hochu, President and CEO, Tire and Rubber Association of Canada, said, “With gas prices continuing to impact travel plans, many Canadians are looking for practical ways to save at the pump. Proper tyre inflation is one of the simplest ways to improve fuel economy and vehicle safety. Regular tyre pressure checks, reducing idling, maintaining a steady speed, accelerating gently and coasting to decelerate all contribute to better fuel economy and meaningful savings at the pump.

“The good news is that the majority of vehicles on the roads today provide drivers with real-time tyre pressure information, giving those drivers the opportunity to maintain their tyre pressure more consistently. Drivers without this technology tend to be less consistent in checking tyre pressure, which leads to reduced fuel economy, shorter tyre life and ultimately higher operating costs. As tyre pressure monitoring systems become universal, drivers will be better equipped to maintain proper tyre pressure and improve fuel efficiency, safety and tyre life.”

Goodyear returns to the legendary Circuit de Spa-Francorchamps this weekend for the second round of the FIA World Endurance Championship season. All 18 LMGT3 entries will compete on Goodyear Racing Eagle tyres at the demanding Belgian track, where the versatile Goodyear Racing Eagle Medium compound has been selected to handle the circuit’s famously unpredictable conditions.

Unlike the previous round at Imola, Spa’s high-speed layout, long straights and dramatic elevation changes place sustained loads on tyres, especially through the compression at Eau Rouge. This makes the Belgian track one of the most aggressive for tire degradation, with a steeper performance drop-off expected over a stint. While differing tire strategies shaped the race at Imola, Spa is expected to reward a more direct, single-stint approach as teams focus on extracting maximum performance from each set.

Given Spa’s location in the Ardennes, highly variable weather is always a possibility, so teams will also have access to the Goodyear Racing Eagle Wet tyre, designed to disperse surface water and provide grip in the rain. Elsewhere this weekend, Goodyear Racing Eagle tyres will be in action at Watkins Glen International for three NASCAR series and at Brands Hatch’s Indy layout for the British Touring Car Championship.

Stephen Bickley, Goodyear Endurance Program Manager, said, “We expect to see less variation in race strategies at Spa. The nature of the circuit means degradation is higher, so teams will focus on extracting maximum performance and are likely to equip new tyres at each stop. There is no left-right bias at Spa, and the load profile doesn’t lend itself to changing only front or rear tyres, so teams may still look to extend stints under safety car or full course yellow conditions, but we expect to see the baseline strategy being more consistent.

“The Goodyear Racing Eagle Medium tyre has proven it can perform at a range of tracks, support front, mid and rear-engined cars and deliver what both professional and amateur drivers in this pro-am class want. At Imola, tyre temperature management was never a concern for LMGT3 teams, even on such a demanding and unpredictable track. Should conditions turn wet at Spa, teams can rely on the Goodyear Racing Eagle Wet tire as a proven and effective solution.”
