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.

Continental is preparing to appear at this year’s TOC Europe with a combined offering of advanced tyres and digital management tools. The company’s presence at the event will emphasise its drive to make port logistics both high-performing and resource-conscious.

The exhibition lineup is built around the theme ‘Driven by Excellence’, featuring the ContiConnect digital tyre platform alongside the new DockMaster Radial tyre. The latter is a purpose-built product for harsh port environments, including automated guided vehicles, reach stackers and heavy forklifts. A company representative has explained that every solution is tailored directly to real customer needs in port operations, blending tyre engineering with data services to enable more energy-efficient and digitally managed workflows.

TOC Europe 2026 will run from 19 to 21 May at the Hamburg exhibition grounds. Continental will receive visitors in Hall B6 at Booth B44, where the focus will fall on operational safety, sustainability and efficiency gains.

ContiConnect plays a central role in cutting tyre management costs and streamlining fleet operations. Properly managed tyre pressure can lower fuel use by up to two percent, while continuous monitoring extends tyre life by as much as 20 percent, simultaneously reducing carbon emissions and operating expenses. The system comes in two forms. ContiConnect Lite is a mobile, app-based entry tool requiring no extra infrastructure, whereas ContiConnect Pro delivers real-time data, automated reports and system integration for large fleets.

The DockMaster Radial tyre stands out for its durable, efficient and robust design. A large footprint and maximised tread volume prolong service life, while the radial build lowers heat buildup over long travel distances. Its rolling resistance is lower than that of bias-ply tyres, improving energy efficiency. An integrated sensor tracks both temperature and inflation pressure, while a specialised rubber compound resists cuts, abrasion and cracking. This makes the tyre especially suitable for intense applications with extended operating ranges and punishing ground surfaces.

Beyond products, Continental offers a data-led tyre consulting service to lower total ownership costs and improve resource use. Experts analyse operational data including distance, speed and active cycle time to advise on vehicle deployment, route planning and tyre selection. Detailed usage studies help match the right tyre to each application, reducing premature failures, extending tyre life and delivering clear efficiency improvements for port operators.

Federico Jiménez, Head of Business Development and Product Management for Continental’s Commercial Specialty Tires, said, “We consistently align our solutions with the requirements of our customers in port operations. With our combination of innovative tyre technology and data-driven services, we enable more energy-efficient, digital, and therefore more efficient operations.”

Titan International has formally entered the rubber track market, a strategic expansion of its product lineup long requested by its customer base. The new Titan Rubber Tracks represent the brand’s first move beyond wheels and tyres, specifically engineered for compact track loaders and mini excavators. This launch introduces an entirely new category for the company, aiming to meet rising demand in tracked compact equipment applications.

The role of tracked machinery continues to grow across construction and rental sectors, where traction and uptime are paramount. Rather than follow industry norms, Titan developed a proprietary premium rubber compound for its tracks, prioritising durability through internal and field evaluations. Extensive testing across varied conditions and multiple regions gathered positive user feedback, with thousands of operational hours confirming reliable performance and longevity.

Both equipment dealers and end users stand to gain from the new line. Dealers receive a high-quality track solution suitable for recommendation, stocking and service support, while operators benefit from a design focused on minimising downtime. The launch encompasses nearly 60 SKUs spread across five tread patterns, fitting over 950 machine models and more than 1,500 specific fitments.

Tread options address mixed surfaces, soft ground, high-impact job sites and general-purpose use. Inventory will reside at Titan’s Des Moines facility to ensure prompt service for OEM and aftermarket needs. Following internal previews at Titan University 2026 and a public debut at the 2026 National Farm Machinery Show, Titan Rubber Tracks are now available for ordering.

Travis Little, General Manager, Ag, Construction and Industrial, said, “Our customers have been asking for Titan to enter this space, but we needed to make sure our tracks are as tough as our tyres. We’ve combined our rubber and engineering expertise to develop a rubber track option that meets our standards and works for our customers. We could have entered the rubber track market sooner, but we wanted to take the time to launch a product worthy of the Titan name. By working with our rubber compounding and engineering teams, we focused on providing a track designed for long-term performance, and we’re confident this is the product our customers have been looking for.”

Chris Smith, Product Engineer, Agriculture, Construction and Industrial, said, “Across all field tests, we have no reports of carcass delamination, guide separation or structural failure, even beyond the above-average expected hours in multiple cases. Testing was also conducted at blue-chip OEM manufacturers where Titan Rubber Tracks exceeded testing requirements on internal durability and high-stress conditions testing.”
