Spinning the wheels would indeed cut down on the tire wear, and I believe that
this has been tested. However, there are problems. When you spin a tire it acts
as a gyroscope and will resists having it's course altered. This can make 
handling tricky as you would have 10 or more wheels all spinning on most 
airliners. Have you ever held a spinning bicycle tire in your hands and tried
to move it? Same effect.

You also need to weigh the advantages against the disadvantages. How much does
the tire wear cost the airline? How much would mantenance on a system to spin
the wheels cost?

Plus you will have the initial cost for the system and the added weight. It is
one more system to break down, etc...

All in all it just doesn't appear to be worth it...
