i check the pressure every two or three days at a station three miles south or one three miles west from home; takes only a few minutes. air's free both places; some charge .75. i try to buy fuel at either as often as possible.Not having to mess around with adding air every few weeks is convenient.
my boss puts nitrogen in her van. gets better mileage. green caps were put on to tell the difference.How do you know if nitrogen has been put in your tires, no way to test it, could try brething it and see if you pass out. :sadpace:
You are correct on the moisture/humidity input, but the van tire would definately have a higher rolling resistance,( less tire on the ground)....try pushing a car with very little air vs a car with a high pressure amount of air in the tires, and then see what one rolls easier:ithank:We started running Nitrogen in our race bike tires in the mid 80's.
Nitrogen has no moisture - humidity. When a tire heats up the
moisture expands creating more pressure (tires psi) that can lead
to less traction (smaller contact patch) or a blistered tire.

I find this hard to believe. A car-van tire that would gain pressure
by the moisture expanding should have a slightly lower rolling resistance.
Lol..How do you "tire" it? and you call me stupid? besides, it's called an analogy, something you evidently have no clue about..you must be 10 years old..Lol!:killingmetry pushing a car with very little air vs a car with a high pressure amount of air in the tires, and then see what one rolls easier
If you tired it you wouldn't have posted this stupid of a reply.

Keep Tires Properly Inflated
You can improve your gas mileage by up to 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.3 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.
lower pressure does not burn more gas because it rolls easier
A freight trains steel wheels roll with something like 1/5 the resistance
of a semi trucks tires.
