Nitrogen filled tires...

[Ruffdaddy]

That doen't apply in this case.

This equation does P x 1/V.

Lol what?

That would just be P/V first of all...and what the fuck is that supposed to mean? Some half assed derivation of the ideal gas law?

[Ruffdaddy]

I'm also not limiting my statement to dirt racing.

So you stand by that it doesn't matter for other racing series?

Qualifying is an example of how important tire temperature is going to rise over a lap or 2. Cooking off your tires in the middle of a flying lap can have a big affect on grid position. Furthermore...1 psi is a huge difference when you're only running 8-9 cold.

It is the equation for Boyle's ideal gas law. Posting from a phone and did not feel like posting the longer version.

You missed a very important qualifier on my first statement. Go back and re-read it. For the record, I run LR tire pressures at around half of what you stated there.

I saw it...but we must have different definitions of ragged edge.

An x doesn't mean proportional...

And that doesn't even come close to the variables in tire pressure for various fill gases.

It is just the simplest equation that I could remember off of the top of my head. My intent was humor and not meant to be taken literately. I am posting from a phone and X is as close as I could get to the correct symbol.

The ragged edge being you've got the rest of the car so sorted out that a few pounds of difference in tire pressure means enough to ruin your setup.

Yeah our definitions are different but so are our methodologies on set up.

So I'd say consistent tyre behavior is pretty important to set up, and nitro is relatively cheap if it holds better consistency. I'm also coming from karting where there isn't that much to mess with setup wise compared to actual suspension systems. And in karting...you need to make sure you're setting up based on accurate tyre data.

Yeah, once you start talking about actual suspension it adds whole other dimensions of shit you need to figure out before you need to worry about your tire changing a few pounds. After a feature race with regular compressed air on a slick track (builds a lot of heat from tire spin) I typically only see a pressure increase of between 2-3 lbs so I lower air pressures according to what I want them to be at when the tire is hot.

thanks for the info fellas.... sounds like it's definitely more of a hassle than anything. Free air it is!

Yes...especially in road cars.
