  >>There's a condition called hysteresis that effects tires.  They get hard 
and lose their elasticity for a number of reasons.  Your tires may have 
plenty of tread on them but for all intents and purposes, are useless except 
to keep the car off the ground.  Buy some new ones.  Hysteresis can occur in 
as little as a few years.  (Hysteresis is the failure of a property to return 
to its previous condition when an external influence is removed.)
