Simulating a wheel rolling over the floor

I'm trying to sumulate a wheel (e.g. a car's tire)rolling over a road in a non linear study.

I put a "bearing load" (I have the sofware in spanish, I don't know if this is the name used in english version)in the axle of the wheel, and I'm using a "reference geometry" to restrain movement to rotatate 0.2 radians, 0 axial traslation, and not restrained vertical/horizontal translation.

Contact restrain between the wheel and the ground is "no penetration" with a friction coefficient of 0.13.

The problem is that the tire rotates but, doesn't "roll" over the ground, it doesn´t move forward, seems like it is slipping in the same place.

I suppose that since the contact is no penetration with friction the wheel must roll forward.

Any input will be appreciated.

Instead of applying rotation to the wheel, why not apply a horizontal translation so it rolls? Perhaps the wheel is slipping by applying rotation to it.

Thanks for your tip Corus, I'm trying it.
