3) Reliable Filling Stations – Nitrogen filling stations deploy modern well-calibrated machines to fill nitrogen in the tyres. On the other hand, normal air has better availability but the machines and gauges used are often inaccurate.
2) Prevents Rusting – Normal air contains water vapour which settles over the rims. This damages steel rims and causes corrosion. Nitrogen gas is pure and devoid of water particles. To check for water particles in tyre, press the valve with your thumb and release some air. If your thumb gets wet, there are water particles in the tyre.
