Each model and size with their radius, Pacejka coefficients, relaxation lengths..... The problem is Pacejka!!.

I have some information:

1. Cosmo (thanks), coefficients for 195/60 R15 and 225/45 R17

2. www.tiretrack.com real test with grip coefficientes and more

And some books,

3. FUNDAMENTALS of VEHICLE DYNAMICS-Thomas DGillespie-SAE (Chapter 10)

4. The AUTOMOTIVE CHASSIS Vol 1 Components design-Genta & Morello-Springer 2009 (Chapter 2) with many real curves.

5. AUTOMOTIVE ENGINEERING-David A Crolla-Elesevier 2009 (Chapter 10.1 and 11.1)

6. www.members.xoom.alice.it/adiaforo The Pacejka equation-Paolo Pinto

7. Altering Pacejka coefficients-Olsen & Page, using RACER

8. Car.ini of differents vehicles...

but I have many doubts

Somebody have more information?
