    Abstract: A noiseless lug tire which runs at a high speed under a heavy load and which satisfies the following conditions.(1) A ratio Wg/Wl is equal to or smaller than 1.0.(2) Each transverse groove for delimiting lugs is not inclined toward an opening of the transverse groove at the kickout side of each lug.(3) Each transverse groove is inclined toward the opening at the stepin side of each lug at an angle of at most 22.degree..(4) Each portion of a center line of the transverse groove in a substantially total region of a length L of the transverse groove is inclined with respect to the meridian line of the tire at an angle within a range from at most 15.degree. measured in a direction opposite to the inclination direction of the transverse groove as a whole to at most 60.degree. measured in the same direction as the inclination direction of the transverse groove as a whole.(5) Each portion of the center line of the transverse groove in a region extending at least 60% of the length L of the transverse groove is inclined with respect to the meridian line of the tire at an angle within a range from at most 2.degree. measured in the direction opposite to the inclination direction of the transverse groove as a whole to at most 30.degree. measured in the same direction as the inclination direction of the transverse groove as a whole.(6) The inclination of the transverse groove as a whole toward the opening thereof in a region extending from the inner end of each transverse groove to a position which is at least 75% of the length L of the transverse groove and at the stepin side of each lug is increased in response to the advance of tread wear.

    Abstract: A taper spring is manufactured by rolling which is achieved by a single-spindle planetary rolling mill having a shiftable upper roll and a planetary roll constructed by a main roll and a plurality of satellite rolls while applying predetermined longitudinal tension to a material by a drawing chuck located at the outlet side of the rolling mill and a pair of relatively movably feed rolls located at the inlet side of the rolling mill.
