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.

Bridgestone has launched a new range of underground mining tyres engineered to perform in extremely harsh conditions, enabling greater productivity with fewer resources. The VMNT, VMDL and VMMS products are specifically designed for underground applications, where abrasive rock, high moisture and continuous operations create one of the toughest environments for tyres.

All three models debut Bridgestone’s Subterranean technology, allowing haulers to carry heavier loads without raising inflation pressure. This innovation also lowers the risk of cuts, penetrations and costly downtime. The tyres form part of the company’s Moving More with Less philosophy, balancing higher capacity, durability and safety to help operators maximise output underground.

The tyres reduce penetrations by enveloping rocks instead of allowing them to cut into the rubber while preserving grip and operator comfort. The VMNT offers extended wear life for underground haulers, the VMDL uses a unique lug pattern for traction on load and haul dump machines and the VMMS features a smooth grooveless design where traction comes from terrain contact, plus cut-resistant sidewalls. Available sizes include 26.5 R25, 29.5 R29 and 35/65 R33.

This release strengthens Bridgestone’s off-road tyre portfolio and reinforces its commitment to innovative solutions that improve productivity, durability and safety in specialised global applications.

Rob Cole, Key Account Manager – Off Road Tyres, UK and Ireland, Bridgestone, said, “These tyres are specifically designed for the harshest terrains that you’ll ever come across. Underground mines are among the most demanding and challenging environments imaginable. The beauty of these tyres is that they can carry 15 percent extra load capacity without increasing the pressure. Traditionally, the thinking in this sector was to make the casing stronger and simply put more air into the tyre to carry more load. In reality, that can be counterproductive in these conditions.

“If a tyre fails underground, it can fail with a tremendous amount of force, costing operators huge amounts of money in downtime and, more importantly, potentially endangering life. The machines themselves are getting heavier, so the tyre beads have also been strengthened to help carry more load safely and effectively. What Bridgestone has developed here is a tyre range capable of handling the severe realities of underground mining while helping operators move more with less.”

The Yokohama Rubber Co., Ltd. has confirmed that its flagship ADVAN brand tyres powered the JR2 Class victor at 2026 WRC FORUM8 Rally Japan, the seventh round of the FIA World Rally Championship. The race took place from 28 to 31 May on courses spanning Japan’s Aichi and Gifu prefectures.

The ADVAN A051T tarmac rally tyres delivered the grip, control and wear resistance essential for navigating the event’s technically demanding stages under high surface temperatures. The JR2 Class is designated for national and regional rally vehicles with engine displacements above 1600 cc and up to 2500 cc. The winning car was a TOYOTA 86 fielded by K-ONE RACING TEAM, driven by Yuta Yamamoto and Shizuka Takehara.

Their well-coordinated, precision driving, combined with the ADVAN A051T tyres’ performance, allowed them to clock the fastest time on every stage except SS10, where a Notional Time was applied. The pair finished over 17 minutes ahead of the second-place car. Yamamoto has now claimed first place in the JR2 Class at Rally Japan for five consecutive years, with ADVAN tyres contributing each time.

Beyond Rally Japan, Yamamoto also competes in the Japanese Rally Championship, where he has secured the JN-3 class series title for three straight years, again supported by ADVAN rally tyres. Rally Japan is the country’s round of the WRC, which ranks alongside Formula 1 and the FIA World Endurance Championship as a premier global motorsport series. The competition is run entirely on tarmac roads, and this year’s WRC calendar features 14 rounds across different nations worldwide.

Tyres Europe has responded to the European Commission’s recent policy package on the EU Deforestation Regulation (EUDR), offering qualified support for measures that reduce red tape. Industry representatives have pointed to proposed exemptions for retreaded and test tyres as a positive step, arguing these products do not present the same supply chain traceability risks as standard new tyres. The move is seen as a way to prevent unnecessary administrative costs for businesses.

A significant point of clarity within the Commission’s documents involves the dual legal status of tyre makers. Under the new framework, manufacturers are considered operators when importing natural rubber but become first downstream operators when selling finished goods. Tyres Europe has endorsed this distinction, stating it prevents the needless circulation of due diligence statement numbers after the raw material has already been cleared at the border. The association believes the same rationale should apply to imported finished tyres, which have already satisfied verification requirements upon entry.

Nevertheless, serious practical hurdles remain, particularly concerning the EUDR’s digital infrastructure. The tyre sector routinely mixes domestically produced and imported tyres within the same warehouses for extended periods, forcing companies to repeatedly consolidate large volumes of due diligence references for customer shipments. Although the Commission has acknowledged the necessity of grouping tools, the current design of the Information System may undermine these simplified procedures. Industry leaders warn that without technically sound solutions, system resilience could be compromised.

Tyres Europe has formally requested that the EUDR’s existing implementation deadline stay unchanged. Instead of delaying the rules, the group urges policymakers to resolve unresolved operational issues through narrowly tailored fixes. The ultimate goal is to prevent duplicate transmission obligations wherever prior due diligence can be clearly demonstrated, ensuring that supply chains remain functional without sacrificing regulatory oversight.

Adam McCarthy, Secretary General, Tyres Europe, said, “The tyre industry supports the objectives of the EUDR and is ready to implement it. After years of preparation, companies now need implementation certainty. The priority now should be to ensure that the remaining operational issues are addressed through targeted refinements and further implementation guidance, rather than through any reopening of the Regulation itself.”
