It sounds like a good idea.

Your thoughts?

I see that the Live Science website is in the business of passing off adverts as science articles. Tyres are inflated with 80% nitrogen normally. An "eco benefit" of inflating ones tyres with nitrogen is supposedly that "Nitrogen makes up almost 80 percent of our air, making it a naturally-occurring element that we're exposed to every day". Pardon my ignorance, but I thought that air, what we normally used to inflate tyres with, is also a naturally occuring gas that we are exposed to every day? And what is the added environmental cost of synthesising nitrogen for this purpose, and distributing it in aerosol cans, whereas compressed air may be gotten wherever there is air?
