摘要： The present invention relates to a method for reducing the phenomena of tyre/ground microsliding local to a shoulder portion of a tyre. The tread band (1) of the tyre is provided with a raised pattern comprising a plurality of circumferential ribs (2, 4, 6) delimited by a corresponding plurality of circumferential grooves (3, 5), and has on its cross section a radially external reference profile (7, 8, 20) comprising a first rectilinear segment (20), local to at least one circumferential rib (2) of the said shoulder portion, which extends axially outwards beyond the edge (A) of the said shoulder portion. This method consists in assigning the said at least one circumferential rib (2) of the said shoulder portion a cross section profile composed of a second rectilinear segment (9) rotated radially lowereds about a point lying on the said first rectilinear segment (20) in a position axially not internal to the said edge (A) of the said shoulder portion.

摘要： A tire and a method of producing the tire, where the tire has a tread layer constituted of tread rubber and a conductive belt provided in an intermediate portion in the width direction of the tread rubber. The tread rubber is constructed from a low conductive continuous rubber ribbon circumferentially wound plural times, and the conductive belt is constructed from a highly conductive thin annular rubber sheet. The conductive belt is provided so as to extend in a width direction region from a part of a top surface of a first tread rubber portion up to a part of a bottom surface of a second tread rubber portion. The structure above improves tire uniformity and enables the tire to be produced in a multi-kind mixed production system. Further the thickness in the width direction of the conductive belt can be constrained to minimum, and a conductive path from the belt to a tread surface can be formed reliably and at low cost.

摘要： To provide a method for calculating a µ-slippage curve for a tire (10) based on laboratory data derived from characteristic values of a used compound, of the road surface and the car without producing a complete tire a method for calculating a µ-slippage curve for a tire (10) is proposed comprising the steps: calculating a friction force Foi(t) between rubber compound and a rough surface (14) based on a friction coefficient µ(t) for different slippage values Sslip and lateral positions (i) of the tire (22), wherein the friction coefficient µ(t) is calculated depending on a sliding velocity vb between the rough surface (14) and a tread block (11) and on a temperature Tq(t) of the tire Sub1. After calculating the friction force Foi(t) the motion of a tread block (11 ) depending o a pressure distribution during the movement of the tread block (11) through the contact area A0 and on characteristics of a tire body (12) is calculated (23). The resulting µ-slippage curve is composed from effective µ-slippage values µslip for different slippage values Sslip (25), wherein effective µ-slippage values µslip are calculated based on the friction force Foi(t) and a nominal force FNI(t) derived from the pressure distribution (24).

摘要： The present invention, in one embodiment, is a method of making a tire (2) with a skin (1) covering at least a portion of the outer peripheral surface of the tire (2). In practicing the method, a partially cured tire (2) and a partially cured skin (1) are provided. The partially cured tire (2) and the partially cured skin 81) are installed in a tire mold with the skin (1) engaging and covering at least a part of the outer surface of the tire (2) and with the skin (1) facing an inner surface of the mold. Heat and pressure are applied to the tire (2) to press the skin (1) and the tire (2) against the inner surface of the mold. The heat and pressure are maintained for a predetermined time period to vulcanize and bond together the tire (2) and the skin (1).
