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 has introduced a 32-mm variant of its Aero 111 road tyre, expanding the range of its most aerodynamically advanced model. Developed in partnership with Swiss Side, this wider version aims to deliver the same drag-reducing performance while catering to cyclists seeking a combination of speed and improved comfort on demanding surfaces.

The tyre’s aerodynamic efficiency is achieved through a patented tread pattern featuring 48 precision cavities that function as vortex generators. This design manipulates airflow around the front wheel to delay separation, maintaining optimal performance across varying wind angles. The result is a significant reduction in drag and an enhanced sailing effect, allowing for greater forward propulsion with reduced rider effort.

Despite its broader profile, the tyre maintains its speed and durability credentials through Continental’s BlackChili compound, ensuring low rolling resistance and dependable grip in all conditions. Protection is provided by the Vectran Breaker layer, and the tubeless-ready casing is compatible with hookless rims. Offered in black sidewall and three widths, the Aero 111 now serves a wider array of road cycling demands.

Hannah Ferle, Road Product Manager, Continental Tires, said, “With the addition of the 32 mm width, we truly are offering aero performance from every angle. Developing the Aero 111 alongside Swiss Side has allowed us to build a tyre like no other, one that performs across even the most demanding conditions. The Aero 111 has already proven the benefits of advanced airflow management, but this additional width allows us to bring those same aerodynamic gains and crosswind-taming technologies to the modern road cyclist who refuses to compromise on comfort.”

TyreSafe has issued a fresh warning to UK motorists regarding the persistent dangers of part-worn tyres, drawing on the findings of recent multi-agency enforcement operations. The safety charity has underscored that despite ongoing efforts to regulate the sector, significant compliance failures continue to place drivers at risk. These concerns are based on collaborative inspections conducted over the past year with Trading Standards, police forces and local authorities, which have revealed systemic issues within the market.

Enforcement actions in Norfolk and Lancashire have exposed alarming deficiencies in the safety and legality of part-worn tyres on sale. In Norfolk, an inspection of nearly 200 tyres across several retail outlets found that over a third were in a dangerous condition, featuring exposed cords, structural damage and inadequate repairs. Remarkably, only a single tyre out of the entire batch satisfied all legal requirements, leading to the immediate removal of unsafe products and subsequent enforcement measures against non-compliant sellers.

Parallel operations in Lancashire painted an equally concerning picture, where none of the 30 part-worn tyres examined met the mandatory legal standards. Every tyre inspected failed to display the compulsory ‘PART-WORN’ marking, and many exhibited serious defects such as embedded objects, sidewall damage and substandard repairs. These discoveries have prompted ongoing engagement with businesses to encourage better practices, though the overall findings highlight a widespread disregard for established safety protocols.

In response to the enforcement outcomes, TyreSafe has noted that educational initiatives have yielded some positive changes among retailers. Certain businesses have enhanced their understanding of legal obligations, reduced their stock of part-worn tyres or transitioned to offering new budget alternatives. Nevertheless, the charity maintains that part-worn tyres remain a high-risk category, as compliance is not uniformly observed, leaving consumers vulnerable to products with undocumented histories and hidden structural weaknesses that are not always visible during a casual inspection.

The organisation has emphasised the critical distinction between tyres fitted to used vehicles and those sold as standalone part-worn products. While the former are acquired as part of a complete car purchase, the latter are individual items whose safety and legality depend entirely on the retailer’s diligence. TyreSafe has reiterated that these tyres must meet strict legal criteria, including a minimum tread depth of two millimetres, successful pressure testing and freedom from cuts or bulges, yet enforcement shows these rules are frequently ignored.

Motorists are being strongly urged to exercise caution and prioritise their safety by sourcing tyres from reputable suppliers and conducting regular checks on air pressure, condition and tread depth. TyreSafe has highlighted that opting for part-worn tyres on cost grounds can prove false economy, given their reduced lifespan and elevated risk of sudden failure. The charity continues to advocate for new tyres as the safest choice, stressing that the unknown history of part-worn products can have dire consequences in real-world driving conditions.

Stuart Lovatt, TyreSafe Chair, said, “Our recent education and enforcement activity revealed a deeply concerning picture of tyre safety on UK roads. Too often, part-worn tyres are being used as a dangerous short-term fix rather than a safe, compliant solution. We encountered vehicles fitted with severely aged tyres that should have been removed from service years ago, alongside single-tyre replacements fitted purely to secure an MOT pass. This creates highly unstable and potentially dangerous combinations, including mismatched summer and winter tyres on the same axle, which can seriously compromise braking and handling. Perhaps most alarming, none of the part-worn tyres we inspected carried the legally required ‘PART-WORN’ marking, highlighting a serious lack of compliance and leaving motorists unknowingly exposed to unsafe and unverified products.”

The Yokohama Rubber Co., Ltd. has announced that a Mitsubishi Triton pickup truck, fitted with its GEOLANDAR M/T G003 mud-terrain tyres, secured the overall championship at the 2026 Asia Cross Country Rally (AXCR). The event took place entirely within Thailand from 10 to 15 August. This victory marks the second consecutive overall win for a Mitsubishi Triton utilising Yokohama’s GEOLANDAR tyres, adding to previous titles in 2022, 2023 and 2025.

The triumphant vehicle was fielded by Team Mitsubishi Ralliart, with lead driver Katsuhiko Taguchi and co-driver Takahiro Yasui at the helm. After third-place finishes in the opening two legs, the pair surged to the front by clocking the fastest time in Leg 3. They maintained their advantage through Legs 4 and 5, the latter being the pivotal YOKOHAMA RUBBER SS5 stage. A careful, puncture-free drive in the final Leg 6 allowed them to finish 2 minutes and 25 seconds ahead of their nearest rivals, securing their first overall AXCR title.

Five of the first 10 finishers were equipped with GEOLANDAR tyres, including the third-place Isuzu D-Max from the ISUZU SUPHAN TRANE TITANIUM YOKOHAMA NEXZTER RALLY TEAM. The GEOLANDAR CTS Rally Team’s Suzuki JIMNY SIERRA, piloted by the Japanese female duo of Koto Haneda and Momo Tsukishima, achieved 19th place overall, second in the T1G class and victory in the ladies' division.

The GEOLANDAR M/T G003 tyre is engineered for superior off-road performance and durability. The AXCR, an FIA-sanctioned event since 1996, covered approximately 2,000 kilometres from Pattaya to Phitsanulok through mountains, jungles and plantations, further validating the capability of Yokohama’s tyre technology.

Hiroshi Masuoka, Director, Team Mitsubishi Ralliart, said, “Again this year, Team Mitsubishi Ralliart selected Yokohama Rubber’s GEOLANDAR M/T G003 tyres for our Tritons entered in the AXCR. This year, Chayapon’s vehicle was the only one that suffered a tyre puncture. A flat tyre can make it difficult for drivers to attack the course with confidence, which greatly affects the flow of the rally. Amid a very tough battle, I think the Taguchi/Yasui team’s ability to drive stably and complete the rally without a single puncture contributed greatly to their overall championship. The GEOLANDAR M/T G003’s highly stable performance supported that victory at this year’s AXCR.”

Linglong Tire hosted legendary Brazilian full-back Roberto Carlos at its headquarters in Zhaoyuan from 14 to 16 August 2026. The Real Madrid official ambassador’s visit included high-level meetings with the tyre manufacturer’s senior management, alongside engagements with key clients and commercial partners. His itinerary featured a comprehensive tour of the company’s primary production facility and an in-depth briefing on its smart manufacturing systems.

The former Real Madrid star explored the firm’s research and development centre and evaluated the Sino-Asia test track, recognised as China’s largest and most advanced proving ground. Carlos expressed considerable admiration for the facility’s professionalism and scale, particularly noting the colossal 63-inch off-the-road tyre displayed at the headquarters. His schedule also included a panel discussion with Linglong Chairman Wang Feng and CEO Lingkun ‘Andy’ Zhou.

Linglong Tire has served as Real Madrid’s Global Tire Partner since 2024, a commitment that extends into the 2026/2027 season. The partnership is activated as the nine-time European champions prepare for their La Liga opener against Real Sociedad at the Santiago Bernabeu on 26 August. As part of the agreement, the Linglong brand secures prominent visibility on the stadium’s digital perimeter boards for all domestic league and cup fixtures.

Additional sponsorship benefits include logo placement on partner boards and the official club website, along with VIP hospitality packages. The collaboration also features advertisements in Real Madrid’s digital and print publications, television spots on the club’s official channel and extensive integration into the club’s media activities, solidifying Linglong’s presence within the Spanish giants’ commercial framework.
