1. A method of tire testing comprising: applying a drive torque to a tire and a wheel assembly about an axis of rotation to drive the tire and wheel assembly and a rotatable drum with the tire in rolling contact with the rotatable drum;controlling a load pressure of the tire against the rotatable drum; andadjusting a lateral position of the tire across a surface of the rotatable drum, such that the surface of the rotatable drum is substantially evenly used after conclusion of a test. 2. The method of claim 1, wherein tire testing includes the use of a programmable lateral position waveform. 3. The method of claim 1, wherein a non-linear ramp rate of the tire back and forth across the abrasive surface of the rotatable drum is performed. 4. The method of claim 1, wherein said rotatable drum includes a surface comprised of at least two different abrasive materials. 5. The method of claim 2, wherein said waveform has between 10 and 1000 points. 6. The method of claim 2, wherein said waveform varies in accord with the tread width of the tire. 7. The method of claim 4 wherein said two different abrasive materials comprise a high microcontent surface and a high macrocontent surface. 8. The method of claim 1, wherein tracks are not created in the surface of a rotatable drum. 9. A method of tire testing comprising: applying a drive torque to a tire and a wheel assembly about an axis of rotation to drive the tire and wheel assembly and a rotatable drum with the tire in rolling contact with the rotatable drum;controlling a load pressure of the tire against the rotatable drum; andadjusting a lateral position of the tire across a surface of the rotatable drum according to a programmable lateral position waveform which optimizes wear of the surface of the rotatable drum based on width of the surface and width of a tire footprint. 10. A method of tire testing comprising: applying a drive torque to a tire and a wheel assembly about an axis of rotation to drive the tire and wheel assembly and a rotatable drum having a surface comprised of at least two different abrasion materials with the tire in rolling contact with the rotatable drum;controlling a load pressure of the tire against the rotatable drum; andadjusting a lateral position of the tire across a surface of the rotatable drum.
