Nitrogen is an inert gas that is used in tyres instead of oxygen. Nitrogen has several properties that make it desirable for use in tyres, such as lower density and boiling point than air (nitrogen has a higher molecular mass), which means nitrogen does not break down at high temperatures the way oxygen does. These properties make nitrogen ideal for use in car or motorcycle tyres, because they can be exposed to high temperatures without degrading like pure oxygen would. Nitrogen also causes less stress on the material inside your tyre, protects against corrosion better than regular air, and provides greater resistance to moisture absorption; all things that are beneficial for your tyres. This is ideal considering the car and motorcycle tyre prices in Sri Lanka, because you can use your current tyres for a longer period of time.
Nitrogen is much denser than air, so it creates less drag on the car
Nitrogen is much denser than normal air, hence it creates less drag on the vehicle. This means your vehicle uses much less fuel when using nitrogen tyres which is great for the environment and also saves you money at the petrol pump.
There are a number of additional benefits that come from replacing regular air with Nitrogen in your vehicle's tyre inflating system. The most important of these is that nitrogen is much more resistant to tyre corrosion than standard air. Of course, the inflation pressure of your tyres will be exactly as you set them up with and there is no risk of under-inflation due to water entering the tyre's inner tube from humidity in the atmosphere which can also cause a loss in fuel economy for your vehicle. Nitrogen provides greater resistance to moisture absorption, all things that are beneficial for your tyres. Many suppliers who sell their tyres online in Sri Lanka, recommend Nitrogen for tyres due to these benefits.
Nitrogen has a lower boiling point than air
Nitrogen also has a lower boiling point than normal air, so it will cool down less when exposed to heat or sunlight. This is particularly beneficial in the summer months where road surfaces can reach incredibly high temperatures, especially in hot countries. This means that tyres running on nitrogen are considerably more resistant against the formation of bubbles within their structure which would cause localised pressure points due to uneven heating.
Nitrogen does not expand
Another benefit of using nitrogen air for your tyres instead of regular air is its ability not to expand like normal air does under extreme circumstances. One situation illustrating this point perfectly occurs during refuelling a car with an empty tank; if you happen to spill some gasoline onto the ground while refuelling (or even worse into your fuel tank) then it is likely that there won't be enough air inside the tank to prevent a massive explosion.
This is because gasoline evaporates much more rapidly than nitrogen and as such will expand rapidly once it comes into contact with air (the air in your fuel tank). The same principle applies when filling up tyres; if you happen to spill some water onto them then they are likely to explode from all of the expanding gas bubbles within their structure.
Nitrogen, on the other hand, simply acts like an inert carrier for oxygen which means that little or no expansion can occur even under extreme circumstances, this makes it perfect for tyres since tyre pressure remains constant regardless of operating conditions.
The pressure in your tyres will be more consistent with nitrogen because of its high density
When you use Nitrogen air it keeps your tyre pressure consistent, whereas if you use regular air then it can cause your tyre pressure to go out of whack. With the added risk of an explosion when using normal air in tyres, this is definitely not something that you want to take a chance with.
The nitrogen fills up all the gaps within your tyre so no oxygen or moisture can enter which means there won't be any additional heat build-up inside them either; this makes for far safer driving conditions than what you would otherwise exist without having used Nitrogen in their structure.
Nitrogen will keep your tyre well balanced and offer a lot more stability on the road as well which provides for far safer driving conditions. In addition to that, nitrogen is good at fighting corrosion and rusting too so you will find your tyres last longer with this kind of air in them instead of regular air as it reduces oxidation build-up significantly as well as reducing corrosive materials entering into tyre structures, so you won’t need to keep buying your car or motorcycle tyres online in Sri Lanka to replace the damaged ones.
You don't need to fill up your tyres as often with nitrogen because it doesn't leak out like regular air does
Regular filling up of air is not necessary when you use nitrogen because it does not leak out as fast, and when taking long trips, you can be assured of a more comfortable ride. Nitrogen is a very stable gas and no leaks can be detected from it, unlike regular air which has many problems with its stability as well as leakage issues due to the fact that oxygen molecules are much smaller than nitrogen molecules. In short you need not refill your tyres quite often when using this kind of air in them.
It is cheaper to inflate your tyres with nitrogen rather than regular air!
All things considered, getting Nitrogen air may be more economical for you as well as beneficial for your vehicle. While regular air is cheaper and readily available, it also has many disadvantages such as leaks due to high oxygen content in the mix of gases that make up normal air which cause problems like flat tyres etc. On the other hand, nitrogen gas does not leak out so easily and therefore you save money by avoiding frequent refills with this kind of an atmosphere for tyres.
