How do you figure? They charge $5 a tire at Cravens..... I mean I guess its a waste of money because air is free:boobies but I dunno im thinking about it and probably gonna do it next week when the weather gets nice again and the rain stops....

Air is 70%(or so) Nitrogen anyway. So thats how i figure Mang.....

Who's running it in their tires? I think im going friday to do the change... Anybody else do this?

Unless you are racing, why do you think you need it?

Gotcha

Yes, but nitrogen is more stable than compressed "air", so it doesn't expand or contract (as much) with temperature variations.

your level of concern for tire pressure may vary

g'dood

If you are bad about checking your tire pressure then go for it, if not save the 10 bucks and use it for a tank of gas.

Tire wear is better, lasts longer than regular air. Nitrogen stays at a constant temperature so tires do not need to warm up before hittin those twisties:rock
I dunno, I have it in my avalanche and no joke its noticeable difference than air.

Here's a thread I posted a little while ago...Nevermind the total morons towards the bottom

THere's the correlation data for you regarding using straight nitrogen and nice, dry compressed air.

Mind you, when you use compressed air from Joe Schmoe's Autobody, it's probably not dry whatsoever.

Im trying to say the tires will warm up quicker

Yep, I'm calling :bulshn that one....read my other thread.

BTW, this data comes from me being a race engineer and the calculations were run with BOC Gases (One of the world's largest suppliers of industrial gasses) internal software. They make billions of dollars worth of decisions with these calculations, I'm pretty sure they're right.


We tried it in a formula car with Bias Ply tires on it.

I used a SCUBA tank to fill tires all weekend on the car. The tire pressures were not adjusted one bit compared to N2 and the driver had no idea that we didn't fill with N2 that weekend. HIs driving style never changed, lap times were identical to the last time we were there, and the tire wear was the same.

It's a common idea that people have, but it's something that comes from archaic information that hit the industry back in the 1960's when good line dryers were few and far between for the average shop.

You are right about staying a consistent pressure, nitrogen molecules are bigger so they dont escape as easy unlike reg air which molecules are smaller, and temp has no affect on it, thats why the use it in airplane tires. also u still need to warm the tires regardless of whats in them. sorry years in the tire buisness, hope that helps. :thumbup

Aircraft tires are filled with nitrogen so that the immense heat built up from the shock load of an aircraft hitting the pavement at 180 kts doesn't cause the O2 inside the tire to cause a fire inside the actual tire carcass AND because a lot of aircraft rubber has special chemicals in it to deal with the extreme cold of 7 miles in the air. Brittle failure under load is a problem they dealt with in the early high altitude aircraft in the late 30's when planes finally started getting to 25000+ feet.

You should read the other thread too. N2 molecules are NOT different sizes than air. O2 and N2 are almost the same size, and N2 makes up 78% of the 'air' molecules anyway.

Helium filled footballs fly further too.......

Oh wait. Sorry.
