trogen filled tires

[meos1]

I have a couple of cars with nitrogen filled tires. One of them was down to 25 lbs after three years. The tire dealer did not do nitrogen and the dealer wanted 20 bucks for a fill up. So I went to a welding gas place and bought a nitrogen B tank and regulator. 240 out the door. Now I have a lifetime supply of nitrogen.

I fill my tires with 78% nitrogen. They lose pressure occasionally too, so I refill them.

I spent my money on good quality pressure gauges - one for autos - one for filled tractor tires. I check the pressure regularly and inflate with my compressor, as needed.

Ha! I'm enough of a nerd I get it!

Hah. Me too. When I bought my '60 Impala, it had very old WWW bias ply tires on it. When I replaced them with new ones, every one had about a liter of water inside. I have no explanation for the water, but the new tires made it handle a lot better.

I assume there is a reason for using Nitrogen, but I can't imagine that it is anything significant. Anyone know what the rationale is behind this practice? If I'm not mistaken, the tire bodies themselves contain anti-oxidants which should make them last for a loooooong time. The tires on my '59 are 16 years old, and they look almost new. I keep it inside and don't drive it hard, but I can't imagine Nitrogen would be worth the hassle.

Maybe the prior owner was prepping the Impala to do some plowing, ha,ha. So I looked up nitrogen filled tires on the web. Nitrogen is supposed to leak out of the tire slower than air. You don't have to check the pressure as often????? The web site said nitrogen is most often used in tires on high performance auto - drag racers, Indy cars etc. I have a sneaking suspicion that nitrogen filled tires on normal autos is a way of getting more $$$ when you buy new tires.

Then when you have to pressure up a nitrogen filled tire - back to the dealer and pay big bucks or do like the OP did and buy a "nitrogen system".

Just got a new car with nitrogen filled tires. As long as the warranty is going they will keep the tires filled with nitrogen and to specs. After that they will have good old fashioned air in them. Darned if I would pay $20 to fill a tire with nitrogen or anything else except maybe rim-guard on my tractor.

Hmmmm. 78% nitrogen for free vs. 100 % nitrogen for $20. Lemme think.

78% nitrogen

I'd imagine that it is the other 21 percent that is the concern but my tires usually look good on the inside it's the outside that weathers and checks.
