摘要： A pneumatic agricultural tire includes first and second rows of angled lugs. Each lug is provided with a leading wall rising up from a tread floor to a leading edge of the lug surface. The leading wall has a wedge shaped leading nose rising up from the tread floor and sloped in the trailing direction so that ground stubble is engaged by and pushed aside by the wedge shaped leading nose thereby reducing stubble damage at a root of the leading wall.
