Default Trail number?

I was reading Niner's page about the geometry of the RIP9 and they talk about a higher trail number. Can anyone explain trail number to me? It looks like it has something to do with the contact area of the tire, but I am not sure how they calculate it or if I am even correct in this assumption.

Thanks.
