Pressure loss

Air is made up of 78% Nitrogen, 21% Oxygen and 1% of other gases. Oxygen found in air is made up of very small molecules which over time permeate or escape the rubber tyre wall. Pure Nitrogen molecules are larger than those found in oxygen and cannot permeate or escape the rubber as easily. This keeps the tyre pressure consistent and stable for up to 3 or 4 times longer than normal air.

Oxygen is a very unstable gas which contains a high level of moisture. When the temperature of a tyre increases, the unstable nature of oxygen within the tyre wall causes the water vapour to react and expand the tyre. Nitrogen is inert and contains no water vapour which prevents this reaction and keeps your tyre pressure consistent and stable in running. This also ensures the correct amount of rubber is in contact with the road at all times.

Oxidisation build up

Oxygen found in normal air contains a high level of water vapour. When a tyre is inflated with air, it causes "oxidisation" or rusting which begins to deteriorate the rubber as it begins to lose its elasticity and strength. Working from the inside out, oxygen, and its destructive properties increases the inner rusting of alloy wheels, affecting the tyre structure and ultimately the tyre’s performance.

Independent testing proves that vehicle users benefit from Nitrogen by:

Saving money on fuel

Correct tyre pressures reduces strain on the engine which results in:

Saving money on replacement tyres

Correct tyre pressures reduces unwanted friction with the road surface which results in:

Increasing Safety

Correct tyre pressures prevents blowouts which results in:

Improving Performance

Correct tyre pressures prevents over contact with the road surface which results in:

Reducing CO2 emissions

By inflating with Nitrogen the vehicle user can be safe in the knowledge that they are also:
