Those values are those from the Pacejka Magic Formula. You can see a lot of examples on the web, even though I've never really looked at the PiBoSo's integration precisly.

Here's a interesting reading if you have a bit of knowledge in dynamics :

As Ricco said. The complete description is in Pacejka's book "Tire and Vehicle Dynamics".

They are based on them but not entirely the same.
