Abstract: The present invention comprises apparatus and methods for testing a tire on a wheel. Particular embodiments of such methods include providing a tire testing surface upon which the tire is to operate and a tire having a radially outer annular side including a road-engaging surface. The methods further include engaging forcefully a radially outer annular side of the tire with the tire testing surface to create a footprint constituting an area of contact between the tire and the tire testing surface, the footprint having a width extending in an axial direction of the tire. The tire is then rotated while engaged with the tire testing surface according to the prior step and a particulate is discharged from a particulate discharge outlet of a particular discharging device, the outlet having a length extending at least substantially across the width of the footprint.
