How to assign PxVehicleDrivableSurfaceToTireFrictionPairs to vehicle ? (Physx 3.2)

I created a table of tire frictions using PxVehicleDrivableSurfaceToTireFrictionPairs but I don’t know how to assign this table to the 4-wheels vehicle being constructed …
How to do this, please ?

Thanks

Hi,

This is passed to PxVehicleUpdates as a function parameter. You are free to change the friction values prior to each update.

Thanks,
