Re: Nitrogen inflated tyres
The advantage of Nitrogen over Air is that it is dry.
The unknown moisture content in Air (and Air is mostly Nitrogen anyway) can give unpredictable pressure rises.
Because pure Nitrogen is dry it always expands at the same rate so pressure rise in the tyre will always be the same.
A predictable pressure rise is very important in motorsport and Nitrogen has been used in motorsport many years.
Most garage airlines have moisture filters to remove water to prevent damage to air-tools so you will get a similar result for no cost.
Remember you still need to check your tyre pressures when cold, which will be impossible if you need to drive to a tyre shop to do it.
Unless you have money that you must spend, don't bother with Nitrogen on a road car.
