Abstract
A pneumatic tire, particularly for tractors or other like vehicles, having a tread portion containing alternating, spaced-apart medium and long lugs proceeding axially inward from a lateral tread edge, and an identical (but opposite in hand) set of long and medium lugs proceeding axially inward from the other lateral tread edge and offset circumferentially so that a long lug emanating from one lateral edge is opposite a medium lug emanating from the other lateral edge. The lugs have bar portions which are smoothly curved axially inward from the tread edge in the direction of intended tire rotation and bulbous head portions transitioned into the bar portions axially inward thereof, to provide excellent traction and wear characteristics while minimizing vibration.
