The conductive portion is formed so as to connect the ground surface and a side surface of a side end portion of the tread rubber in a tire meridian circle cross section. The conductive portion having a rubber hardness which is different from the tread rubber, and has a stem portion and a plurality of branch portions. The stem portion heads for an inner side in the tire width direction from the side surface of the side end portion of the tread rubber so as to terminate at an inner portion of the tread rubber. The plurality of branch portions are branched from a plurality of positions of the stem portion so as to head for an outer side in the tire width direction and be exposed to an outer surface of the tire. | 08-28-2014 |
20140283964 | ANTISTATIC VEHICLE TIRE AND METHOD OF MANUFACTURING SUCH A TIRE - The invention relates to a vehicle tire comprising a tread portion and a package of reinforcement layers arranged underneath the tread portion. The tread portion comprises a tread layer, a tread base layer arranged underneath the tread layer, and at least one rubber member that extends in the radial direction of the tire from the ground contacting surface to the reinforcement package. The tread layer rubber composition has an electrical resistivity at room temperature of more than 108 ohm-cm, the tread base layer rubber composition of between 106 ohm-cm and 108 ohm-cm, the member rubber composition of less than 106 ohm-cm; and the rubber composition of at least one layer of the reinforcement package has a electrical resistivity at room temperature of less than 106 ohm-cm. The vehicle tire combines a low rolling resistance with improved conductivity to avoid build-up of static electricity. | 09-25-2014 |

20160039252 | PNEUMATIC VEHICLE TIRE AND METHOD FOR MAKING A PNEUMATIC VEHICLE TIRE - A pneumatic vehicle tire has a carcass with at least one carcass ply. The surface of the carcass ply has an overlay made of an electrically conductive rubber mixture. The overlay extends continuously from an electrically conductive bead base to a superstructure and contacts the superstructure. A method for making a pneumatic vehicle tire includes the steps of making a carcass ply, covering a surface of the carcass ply with a continuous overlay made of an electrically conductive rubber mixture. The overlay contacts an electrically conductive bead base and the superstructure in the finished pneumatic vehicle tire. | 02-11-2016 |
20160039257 | TIRE WITH TIRE TAG - A pneumatic tire includes a tire body having a crown portion and a pair of sidewalls. At least one reinforcing belt is disposed in the crown portion of the tire. A tag is carried by the reinforcing belt. In one embodiment, the tag is disposed in the location of one of the reinforcing cords that is disposed in the reinforcing belt. In another embodiment, the tag is disposed at the splice of the reinforcing belt. An alternative version of the tire has the tag carried in a depression formed in the outer surface of the tire sidewall. The tag may be encapsulated with an encapsulation material that is also disposed in the depression. | 02-11-2016 |
20160059642 | PNEUMATIC TIRE - In a pneumatic tire, a rubber hardness of a conductive portion is greater than a rubber hardness of a non-conductive portion, the conductive portion is formed from an inner end portion toward an outer end portion in a tire diametrical direction of the land portion by continuing a plurality of inclined portions which are inclined in relation to the tire diametrical direction, and at least one conductive portion is arranged in an outer region which is an outer side at the time of mount to a vehicle, and the inclined portion arranged at an outermost side in the tire diametrical direction is arranged so as to be inclined from an inner side toward an outer side in a tire width direction as the inclined portion goes from an inner side to an outer side in the tire diametrical direction, in the conductive portion arranged in the outer region. | 03-03-2016 |
20160121665 | PNEUMATIC VEHICLE TIRE - A pneumatic vehicle tire is configured for mounting on a rim. The tire includes a bead region having a bead core disposed therein and a side wall. A carcass insert extends around the bead region and has a turn-up extending in the direction of the side wall. A rim rubber forms an outer surface of the bead region and includes a first rim rubber part made of an electrically non-conductive rubber mixture and a second rim rubber part made of an electrically conductive rubber mixture. The second rim rubber part runs within the tire and forms an electrically conductive connection to the rim while the first rim rubber part extends beyond the rim flange and is in contact with the rim flange. The first rim rubber part is made of a rubber mixture having a low hysteresis. | 05-05-2016 |
