Nitrogen Air Vs Normal Air
Why we need to fill air?
To ensure the proper amount of friction created between tyre and air, to experience smooth driving.
Low pressure can lead to accidents due to instability, and hard to handle the turns of the road, and driving with zero air on tyre, will affect the rim inside and could lead to complete ruin off.
Difference between normal air and nitrogen air?
Both airs can be used to fill the tyres of bike/car, but both has diff composites and physical structure in which normal air has 78% Nitrogen , 21% Oxygen and 1% Other gas, whereas the nitrogen air is composed of 95% Nitrogen, 5% Oxygen and small negligible amount of water vapour.
By molecular structure, Nitrogen has big molecular structure compared to oxygen as oxygen has additional one proton and neutron compared to nitrogen, so more attraction in oxygen molecule with protons and electrons around it, so more force, the less overall space it consumes than Nitrogen
What is the result/diff between using normal and nitrogen air?
Since the normal air has more oxygen and vapour, the more we travel, the more tyre revolves, the more friction with road, the more heat is caused, the more it evaporates, the quick the tyre pressure will be lost. Whereas the same case happens in Nitrogen air but since the vapour and oxygen content is less, the process happens slowly, so the tyre pressure will be reduced slowly.
Over two weeks of period, 8-10 psi will be reduced on filling normal air whereas only 2-4 psi will be reduced on filling nitrogen air.
What is the impact?
The more air present in tyre, the less efforts put by engine to run, the less petrol it takes, the more mileage we get. Doesn’t mean you will see more diff in mileage on using nitrogen and normal air, but slight difference will be there. Apart from this, tyres too have multiple layers, the more oxygen & vapour we have, the more it gets oxidised with iron of aluminium rim of the tyre, the more rust it will cause in long run.
Which one to choose?
The choice is completely depends on the person who drives the vehicle, he/she can fill either normal air or nitrogen air. Preferably in long travel, good to use nitrogen air as it stays long and its quiet still possible that multiple petrol bunks on highway side do have nitrogen airs. Whereas, if you are city rider and quiet wont go very fast more than 40-50 km per hour, good to go with normal air, as the air goes out quietly slowly from tyres and most of city petrol bunk doesn’t have nitrogens.
Any issues/discrepancies on shifting between both airs?
Note that switch between normal air to nitrogen or vice versa doesn’t affect any engine parameters or other. Just while filling the other opposite gas, the existing one has to be taken out completely and the new one has to be filled.
Bonus:
Ideal air psi= 32 to 35
