Abstract
A pneumatic tire particularly useful in agriculture is improved due to the bars of its tread having an average angle of inclination, with respect to the longitudinal plane of symmetry, which is greater at their end adjacent the tread edges than at their other end and walls whose slope on the side of the leading edge of the bar is more abrupt towards the center of the tread than towards the edges of the tread and walls whose slope on the side of the trailing edge is more gentle towards the center of the tread than towards the edges of the tread.
