Most tyres are filled with compressed air, which when dry consists of about 78 percent nitrogen, 21 percent oxygen and 1 percent other gasses by volume. Water vapour (humidity) can make up to as much as 5 percent of the volume.
Filling your tyres with nitrogen mainly does two things:
1) it eliminates moisture
2) replaces small oxygen molecules with big nitrogen molecules, reducing the rate at which compressed gas diffuses through porous tyre wall
That means, theoretically, that a tyre filled with big nitrogen retains optimal pressure longer, leading to more uniform tyre wear and better gas millage.
So, the advantages are:
- reduced fuel consumtion
- increased life of tyre
- increased safety and comfort of a journey
- ecological note - by using nitrogen, you can keep tyres in a better condition so at the end of their life cycle, they can be more easily reconditioned, leading to a substantial reduction in they type of waste.
