Abstract: A pneumatic tire includes a plurality of protrusion portions extending along a tire side surface of a tire side portion in a direction that intersects a tire circumferential direction and a tire radial direction; the plurality of protrusion portions each including an intermediate portion in an extension direction that includes a highest position of projection height from the tire side surface, and an end portion on either side of the intermediate portion in the extension direction that includes a lowest position of projection height from the tire side surface. The highest position of projection height of the intermediate portion is in a range of 20% of a tire cross-sectional height from a tire maximum width position to an inner side and an outer side in the tire radial direction, and a ratio of a total width SW and an outer diameter OD satisfies a relationship of SW/OD?0.3.

Abstract: A pneumatic tire includes a plurality of protrusion portions extending along a tire side surface of a tire side portion in a direction that intersects a tire circumferential direction and a tire radial direction. Each of the plurality of protrusion portions includes an intermediate portion and an end portion. The intermediate portion in an extension direction has a highest position of a projection height from the tire side surface. The end portion is provided on either end of the intermediate portion in the extension direction, and has a lowest position of the projection height from the tire side surface. The highest position of the projection height of the intermediate portion is disposed in a range of 20% of a tire cross-sectional height on an inner side and an outer side in the tire radial direction from a tire maximum width position.

Abstract: A water shield structure for a transportation device and the transportation device having such a water shield structure. The transportation device is preferably a self-balancing device and may include a friction drive motor. The water shield structure helps reduce the entry of moisture from a riding surface into the wheel envelope or drive mechanism of the device. The water shield structure may extend laterally from a wheel and be enclosed, at least in part, in a housing.

Abstract: A tire/wheel structure includes a body, such as an automobile tire, and guide blocks mounted to two sidewalls of the body in a circumferentially arranged cascade series. Each guide block has a side facing a forward rotation direction of the body and forming at least one inclined guide face in such a way that the inclined guide face and an adjacent one of the guide blocks define therebetween a wind-assisting groove, whereby when the body is in a forward rotating condition, the inclined guide faces of the guide blocks and the wind-assisting grooves help enhance airflow guiding, reduce wind resistance, and generating an assistive driving force and when the inclined guide faces of the guide blocks and the wind-assisting grooves are moved to a position in a lower half of the circumference of the body, a follow-the-trend driving assisting force and a moving stabilizing effect are achieved.

Abstract: A pneumatic tire comprises buttress parts each provided with a row of protrusions arranged circumferentially of the tire. The protrusion has a radially outside wall surface rising from the surface of the buttress part, a radially inside wall surface rising from the surface of the buttress part, and a top surface extending between the radially inside wall surface and the radially outside wall surface. The radially outside wall surface starts to rise from the surface of the buttress part at a certain distance from the tread edge so that the minimum radial distance Kmin from the tread edge to the protrusions is in a range of from 5 to 15 mm.

Abstract: Tire having a tread, sidewalls axially and radially extending towards the inside of the tread, the tread having a running surface, intended to be in contact with the ground during running, and axially lateral faces on either side of the tread, this tire having, furthermore, at least on one of the sidewalls and near the tread, a circumferential rib intended to modify the height of expelled water in the transverse direction (corresponding to a direction parallel to the rotation axis of the tire) in the case of the tire running on wet ground. The circumferential rib comprises a deflector device for deflecting the stream of expelled water in the case of the tire running on water-covered ground, this deflector device being formed from a plurality of protuberances projecting from the circumferential rib and being arranged in an oblique direction with respect to the transverse direction.

Abstract: A pneumatic tire for use with telescopic material handlers includes a first concentrically continuous sidewall protector rib projecting axially outward from the sidewall and located above a midpoint of the sidewall. A second non-continuous sidewall protector rib is located concentrically outward of the first sidewall protector rib. The tire is a relatively low aspect ratio tire having a relatively flat sidewall profile. This provides a tire having the advantage of added sidewall protection without increasing the overall width of the inflated tire.

Abstract: Pneumatic radial tires are described having belt layers deposited under a tread and a ring-shaped water-splash control rib (100) formed on the sidewall (20), wherein the upper profile Lb of the rib is positioned above a continuation line (Ca) which extends along an average profile of an outmost belt layer and which is divided in to upper and lower profile of the outmost belt layer, the rib comprising drainage grooves or drainage protuberances in the upper profile of the rib, the height h of the rib is 0.085-0.115 times the width TW of the tread (0.085TW?h?0.115TW).

Abstract: A tire for a heavy vehicle having beads, sidewalls and a crown, the crown having a reinforcement armature formed of at least two working plies, is provided with a protuberance for deflecting sprays. To deflect the flow of water ejected laterally by this tire during travel on water-covered ground, without adversely affecting the thermal level of said tire, provision is made to arrange on at least one of the sidewalls a protuberance which is limited by an upper wall radially to the outside and a lower, wall radially to the inside, the intersection of said walls being along a line joining points C which are located axially farthest to the outside of said protuberance, the angle &agr; between the axial direction and a straight line tangent both to the edge of the tread and to the protuberance being less than 45°. Furthermore, the upper profile of the protuberance intersects the sidewall profile at a point K located within the extension of the average profile of the radially outermost crown ply.

Abstract: An aircraft tire having a liquid deflector extending outwardly from at least one sidewall, a first plurality of grooves in the tread and a second plurality of grooves disposed axially outwardly of the tire relative to the first plurality of grooves for directing water from the first plurality of grooves toward the respective liquid deflectng means. The first plurality of grooves may interconnect to direct water to the second plurality of grooves each of which may extend at an angle of between about 25 and 35 degrees relative to a radial plane of the tire passing through the respective groove.

Abstract: A removable resilient shield is maintained proximate the sidewalls of a tire for off-the-road vehicles to protect this critical area of the tire from damage due to contact with external objects such as rocks. The shield is attached to the rim flange. The radially inner portion of the shield is discontinuous to prevent accumulation of debris between the shield and the sidewall of a tire mounted on the rim.

Abstract: A removable resilient shield is maintained proximate the sidewall of a tire for off-the-road vehicles to protect this critical area of the tire from damage due to contact with external objects such as rocks. The shield is secured to the terminal portion of the rim flange. The radially inner portion of the shield is spaced axially of the rim and at least one radially extending passage is provided for removal of debris from between the shield and the sidewall of a tire mounted on the rim.
