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).

摘要： A method for detecting strain state of a tire, a device for detecting a strain state, and a tire can reduce generation of deterioration and can be used for a control system such as a stability control system or the like. Rows of electric conductors formed of plural metal foils (electric conductor pieces)(101, 102) embedded in rows in a tire (300) in its circumferential direction with a predetermined spacing are provided on two different layers. A pulse electromagnetic wave is radiated to faces of the metal foils (101, 102) of the individual layers from a monitor device (200) provided at a wheel house (400) of a motor vehicle. A pulse electromagnetic wave reflected by the metal foils (101, 102) of the individual layers or by members other than the foils is received by the monitor device (200). Process of measuring time period from the radiation of a pulse electromagnetic wave until the reception of a reflected pulse electromagnetic wave is repeatedly performed. Time period that is measured when the tire (300) has no strain is memorized in advance as a reference value. A strain state of the tire (300) is detected by comparing the time period measured and the reference value.

摘要： An aircraft pneumatic tire that has deeper grooves without causing deterioration in the heat resistance of a top tread and thereby can increase the number of landings per tread is provided.
At least part of a top tread 2 in the width direction of the tire has a two-layer structure consisting of a base tread layer 11 and a cap tread layer 12 stacked in the radial outward direction in this order. At least one circumferential groove 4a to 4d is provided in the surface of the top tread 2. The base tread layer 11 and the cap tread layer 12 satisfy the relationships expressed by the following formulas (1) and (2): 1.05 M ( 50 ) b / M ( 50 ) c ≤ 1.30 1.04 R b / R c ≤ 1.20 (wherein M(50) b and M(50) c denote 50% moduli of the base tread rubber and the cap tread rubber, respectively, and R b and R c denote the resiliences of the base tread rubber and the cap tread rubber, respectively).
