What is Nitrogen in Tyres for?
Nitrogen-inflated tyres have the advantage that nitrogen gas does not support moisture or combustion. Compared to ambient air, which contains approximately 78% nitrogen, 21% oxygen, plus miscellaneous gases, pure nitrogen is a non-flammable inert gas.
Basically, it is dry air where all oxygen is removed. Also, the molecules in nitrogen are bigger than those present in normal air with oxygen which means it is harder for them to escape out of the tyre.
Advantages of using nitrogen in tyres
The ultimate result can be seen with the longer duration of the tyres when inflated with nitrogen.
Nitrogen-inflated tyres are also used in professional motorsport. Dry nitrogen minimises variations in tyre pressure, which is why nitrogen-inflated tyres are used in professional motorsport, where the slightest change in pressure can affect performance when driving a high-performance vehicle at extreme speeds.
The result is that it makes the tyre harder and prevents deforming so it will help lose less pressure with time.
Is nitrogen better than regular air in tyres?
Nitrogen is not necessarily better than inflating tyres with air for passenger cars. If your car is high performance it can definitely enhance tyre life. But for a regular everyday use the difference won’t be very noticeable. We suggest you fill your tyres with nitrogen only if the price is low or if it is a free service. In truth what matters is to keep the right pressure and regularly check it.
Do I really need nitrogen in my tyres?
You will have to inflate your tyres less often but the price is not the same as when inflating with air. It is a good idea for people who drive sports cars or for track cars because of the more lasting pressure. Although, you can fill with nitrogen the tyres of your new car for the first time if you want to spare a little more money on the first filling.
Can you put air in tyres with nitrogen?
Yes you can. If you do it repeatedly, there will no longer be nitrogen in the tyres anymore.
What is the benefit of nitrogen gas in tyres?
Extending the tyre pressure by creating a slower loss in tyre pressure. Instead of losing 1 to 3 PSI per month, with nitrogen in the tyre, the pressure goes down ⅓ to ⅔ of what would normally go down with air.

What should I check before changing wheel size?
Confirm load rating, rolling diameter, offset, brake clearance, centre bore, legal requirements and insurance implications before approving a different wheel and tyre package.
