Nitrogen filled tires.

My understanding about nitrogen in a tire is that it really has marginal positive effects (yea, just a little, maybe) on performance and longevity, but has an outstanding benefit to the dealer that sells it to you.......namely an extremely high profit margn. There is a reason Costco can refill your tires for free after they sell to you, because it is very cheap.
I can't help but think that the guy that thought up the idea for nitrogen in tires is the same one that came up with marketing bottled water on a massive basis.

 

That's my point. Why? As expensive as tires are, buying nitrogen so you don't have to do minimal tire maintenance just doesn't make sense. Stick 'em, feel 'em, and put some FREE air (78% nitrogen) in 'em when necessary. My rubber is a $6,000 investment- I can spend 5 minutes in the AM making sure they're tip-top.

 

we used nitrogen mounting race tires, the reason was a air compressor took forever, a nitrogen bottle would mount untold numbers without waiting on the compressor to build back up. I leased the bottle and refills were 15 dollars for a tall bottle like for an acetylene torch, one bottle would last a race season. the moisture is what affects the air pressure and race tires will still leak down. just think if the nitrogen doesn't leak out, when you keep adding regular air to a tire it would eventually be almost all nitrogen, think about it.

 

And you say I'm full of ####?

Although I would actually have loved to see 820 cases in a Chevy pickup. You did a good job destroying that chevy and saving somebody else a lot of headache your are a great person
