The invention relates to the lugs of tires intended to be mounted at least on the driving wheels of agricultural and industrial tractors; said lugs have the front sidewall, with respect to the running direction of the vehicle when in service, shaped according to a curvilinear profile which produces considerable advantages as regards the wearing-out, the efficiency, and the lifetime of the tire itself. This curvilinear profile is expressed by the equation: y=Ax3+Bx2-Cx where A, B and C are constants linked to the geometry of the lug. |
