Hello everybody, I'm looking for the complete Pacejka's coefficients of a Truck tire with the following nomenclature 195/75 R16 c. Specifically the coefficients that I need are similar to these:

! USE_MODE specifies the type of calculation performed:
! 0: Fz only, no Magic Formula evaluation
! 1: Fx,My only
! 2: Fy,Mx,Mz only
! 3: Fx,Fy,Mx,My,Mz uncombined force/moment calculation
! 4: Fx,Fy,Mx,My,Mz combined force/moment calculation
! +10: including relaxation behaviour
! *-1: mirroring of tyre characteristics
!
! example: USE_MODE = -12 implies:
! -calculation of Fy,Mx,Mz only
! -including relaxation effects
! -mirrored tyre characteristics
!

In the technical subforum > car.ini tyres, many people show information about tyres with the pacejka model, but you need much more information. See the refered bibliography.
