Mt dealer went ahead and filled my tires with Nitrogen, I know nothing about this new system, can someone enlighten me?

 

My uncles Sequoia came with it... He lived in the country and didnt like em... Idk why

 

Lighter and denser, so your tires shouldn't lose air as easily. Pain in the but to maintain them though. I just added regular air as my tire pressure decreased in my cadillac.

 

yeah its kinda BS. Regular compressed air works just fine.

 

They nailed it. The biggest problem with nitrogen is availablity. In my town, I don't know of any place I could get nitrogen, but I have an air compressor in my garage.

 

It is just a gimmick. Helps garage more than it helps you.

 

Air mostly contains nitrogen anyway...The values below make up 99.998% of air:

Nitrogen N2 78.084%
Oxygen O2 20.947%
Argon Ar 0.934%
Carbon Dioxide CO2 0.033%

I think filling your tires up with nitrogen is a gimmick on vehicles. Aircraft tires are filled with nitrogen...I understand why though. I can't justify it on cars/trucks...

 

Ok then, why are aircraft tires filled with nitrogen?

How does it help aircraft tires to be filled with nitrogen?

Thanks

 

The tire has a longer life span. Don't need to service as often (smaller molecules) due to air loss. A Non-dry air source has moisture in it.

Go to the local gas station and use their air compressor. How much moisture is on your hand?

Tires heat up on take-off due to friction, they heat-up upon landing due to friction and brakes and they cool down (freezing temperature's and moisture = ice) in flight. It also allows for one or two additional re-treads.

Less tire servicing and tire change's = a happy Crew Chief (technician).

 

Thanks! and there you go Except, I've never heard of or experienced retreading an aircraft tire...

 

How much longer do the tires last then, percent wise?

 

The Air Force uses or did use Goodyear re-treads on Cargo Aircraft. I've been away from aircraft for a few years so I'm not certain if they still use re-treads. There was mention of getting away from re-treads but not certain at this time.

Any USAF Crew Chief's want to piggy back on my comment?

Not sure about Civilian aircraft?

Nitrogen is not a gimmick but it isn't cost effective in automotive tires. They wear out before you see any real benefits.

 

A little off topic here, but my FX4 came with 20" Pirrelli Scorpions, yet the spare tire is a 18" Goodyear...Shouldnt the spare be a 20" as well?

 

Not sure? My 1994 Lightning came with 275/60-17's from the factory with a 235/75-15 steel wheel spare.

What size 18"?

 

Nitrogen doesn't pass through the tire as easily as air does.
I've filled tires that stay the same pressure for 6 months or better.
You will also see trucking firms use nitrogen since it means less maintenance of air pressure in their tires and results in better fuel mileage because the tires just don't go soft as quickly.
Also, works well for those of you will trailer tires, boat or rv. Those tires tend to dry rot before they wear out. Nitrogen filled tires don't do that. Typically gas station air pumped into tires has a lot of moisture in it which Nitrogen doesn't. The passage of moisture through the tire is what causes dry rot.
BTW, Costco puts it in all the tires you buy from them (doesn't charge for it like other do) and typically has a nitrogen pump line outside for you to refill.
