20100065180 | PNEUMATIC TIRE - A belt reinforcement layer | 03-18-2010 |
20100252163 | PNEUMATIC TIRE FOR MOTORCYCLE - A pneumatic tire for motorcycles is provided which can improve traction performance especially during sharp cornering by largely leaning a vehicle, and stability during leaning of a vehicle without diminishing other performances. A pneumatic tire for motorcycles having a tread portion | 10-07-2010 |
20110214792 | PNEUMATIC TIRE FOR MOTORCYCLE - A pneumatic tire for motorcycles is provided which can improve the traction performance especially during sharp cornering by largely leaning a vehicle (motorbike) followed by acceleration, and the stability during leaning of a vehicle in addition to enhancing the steering stability at high speed. | 09-08-2011 |
20120193008 | PNEUMATIC TIRE - There is provided a pneumatic tire having excellent uneven wear resistance performance, low rolling resistance and durability of side portion's appearance. The pneumatic tire comprises a carcass as a framework consisting of at least one carcass ply troidally extending between bead portions embedded with a pair of bead cores and turned around the bead cores from an inner side to an outer side in a tire width direction, a belt comprising at least one inclined belt layer and a tread successively disposed on a radially outer side of a crown portion of the carcass, wherein a ratio BD/BW is in a range between 0.01 and 0.04 in a section of the tire in the width direction in a state where the tire is mounted on an application rim, where BD is radius difference between radius at a central portion and radius at an end portion in the tire width direction of the outermost layer of the inclined belt layer and BW is a width of the outermost layer and CSEh is larger than SWh, where CSEh is a shortest distance from an end of a turn-up portion of the at least one carcass ply to a line drawn in parallel with a tire rotation axis at a bead toe and SWh is a shortest distance between a line drawn in parallel with the tire rotation axis at a maximum width position of the tire and the line drawn in parallel with the tire rotation axis at the bead toe. | 08-02-2012 |
20140138002 | PNEUMATIC TIRE - Provided is a pneumatic tire having at least one carcass layer as a skeleton extending in toroidal shape over a pair of bead portions, at least one belt layer and a tread disposed on an outer side in the radial direction of a crown portion of the carcass. In a tire section in the widthwise direction in state where the tire is assembled to an application rim, ratio BD/BW of radius difference BD between radius at a center portion and radius at an end portion in the widthwise direction of an innermost layer of the belt layer, to width BW of the innermost layer, ranges from 0.01 to 0.04, and ratio TD/TW of radius difference TD between radius at a center portion and radius at an end portion of the tread in the widthwise direction of a tread ground surface, to tread ground-contact width TW, satisfies BD/BW | | 05-22-2014 |
20150266346 | PNEUMATIC TIRE - A pneumatic tire, having a plurality of sipes formed in land portions of a tread thereof so as to each extend in the tire width direction, characterized in that: in a cross section of the land portion orthogonal to the sipe extending direction, provided that an imaginary sipe main line links two ends in the tire radial direction of each sipe, at least two of the sipes are “inclined sipes” each having the sipe main line inclined with respect to the tire radial direction; each inclined sipe has inner bent portions each protruding with respect to the sipe main line with peaks positioned deeper than 20% of the sipe depth; and the sipe main line(s) of at least one of the inclined sipes are inclined in a direction opposite, with respect to the tire radial direction, to the sipe main line of any of the other inclined sipes. | 09-24-2015 |
