Semi off-topic: Is Nitrogen really good for tires?
Good, how? They’re filled with about 80% nitrogen, regardless.
Yes, no oxygen.
It makes your valve caps green…
Nitrogen doesn’t expand and contract like air does with changes in temperature which means the tire pressure doesn’t change with the temperature
For most people it makes zero difference. The air has about 80% nitrogen in it by default.
It’s used on jet liner tires.
“Is Nitrogen really good for tires?”
Tires are designed to use regular air.
It should not matter, most rims made of corrosive resistant material or coating and not prone to oxidation damage. Little leaks out of the rim can start corrosive spots as the outer rim is exposed to the elements and gets dinged and scratched. Those spots can start corrosion though whether you have pure nitrogen air or regular air in the tires bucause it’s exposed to the air and rain. I think it’s just a way to try and charge extra. Regular air 78% nitrogen 16 % oxygen and the rest is mostly inert gas, except of course the evil 0.04% carbon dioxide.
Highly overrated for all the reasons it is recommended. It’s a money marker for car dealers.
If you have a fetish about maintaining the air pressure in your tires to the Nth degree all you need to do is get a $35 compressor and check your tires a couple of times a month.
I check my motorcycle tires several times a week, the cars? Maybe once a month.
Eh. Maybe in racing applications. Maybe. Mostly it’s a crock. Doesn’t matter in normal driving.
