All tyres allow gas to travel through the sidewall, which is why you need to regularly check your tyre pressures.
Filling tyres with Nitrogen means that your tyre pressure will remain correct for longer because the rate at which Nitrogen passes out the walls of your tyres is slower than oxygen.

Molecule SizeThe physical size of a Nitrogen molecule is larger than that of compressed air. Nitrogen will escape from a tyre over a longer period of time than compressed air
Low Tyre Pressures...Create more resistance to movement and therefore more energy is required to move your car
Correct Tyre Pressure...Reduces the resistance to movement compared with an under-inflated tyre, and ensures optimum fuel efficiency
Save Money, Reduce CO2As Nitrogen helps to keep your tyre pressure correct for longer, it can help you increase your fuel efficiency for longer and therefore decrease fuel consumption. Also, as less energy is required it can help reduce your vehicles CO2 emissions
tyres cause resistance, which means that more power is required to move the
vehicle forward which uses more fuel and generates more C02. Keeping
your tyres at the correct pressure can therefore help you save money on fuel
and reduce the amount of C02 produced by your vehicle.
