Spinning airplane wheels before landing

Why don't commercial jets start the wheels rotating before landing?

When an airplane lands, that burst of smoke is rubber burning off the tires as the wheels go from not rotating at all to rolling without slipping in a very short time. This must wear the tires pretty quickly, adding to the operation cost. There are various patents dating as far back as the 1940's for fins on the wheels or the tires to get the wheels spinning before landing. But it doesn't seem that any of these inventions are actually used. Why?
