Not directly, no.
High purity nitrogen has been used for decades in Nascar, Formula One, the Tour de France, the US Military, and many other applications where safety, speed and economy are vital – so you would think the answer would be yes.
However, it’s accurate tire pressure which makes the difference, and nitrogen can help maintain this for longer periods of time.
Nitrogen does offer an advantage of its own over air. Air includes a small percentage of water which will corrode your wheels once it’s inside your tires. Therefore using pure nitrogen will remove moisture which may lead to corrosion – and pressure change.
There are therefore two benefits of nitrogen which will help maintain your accurate tire pressure for longer – and it is the latter which results in modest savings in fuel and tire life.
If you decide to try nitrogen your tires will need filling and purging several times in succession to completely remove air from your tires, which can be time consuming. PCL’s ACCURA Mobile allows the operator to preset the pressure for a standard inflation top-up, or a purge and fill, so that they can get on with alternative work whilst tires are inflating.
Once this has been done, do not expect to feel any significant difference unless your tire pressure was seriously inaccurate before you changed to nitrogen. You may eventually notice some savings in fuel and maintenance costs but remember – this is due to accurate tire pressure and nitrogen’s ability to help keep it constant.
