摘要： A pneumatic tire for a motorcycle includes a tread having a tread surface which makes contact with ground, a pair of beads each positioned on a radially inner side of the tread, a carcass bridging one of the beads and the other one of the beads, and a reinforcement layer laminated on the carcass on the radially inner side of the tread. Each of the beads includes a core and an apex extending from the core in a radially outward direction, and the apex of each of the beads has an outer edge positioned on a radially outer side of an edge of the tread surface.

摘要： Improving endurance of bead of radial tire for heavy vehicle. Tire has two beads (2) contacting rim (3) connected by carcass reinforcement (4) having carcass layer (5), with main part (6) wrapped, in each bead (2), axially from inside towards outside of the tire, around bead wire (7) having diameter (L), to form turnup (8) having free end (E). Each bead (2) has filling element (9) with filling compound (10) and extending radially towards outside from bead wire (7) and axially between turnup (8) and main part (6). The distance (I) between turnup (8) and main part (6) decreases continuously from bead wire (7) as far as a first minimum distance (a) reached at a first point (A) of turnup (8), then increases continuously from the first point (A) of turnup (8) as far as a first maximum distance (b) reached at a second point (B) of turnup (8).

摘要： A pneumatic vehicle tire includes a carcass extending between two bead cores. A belt structure is provided between the carcass and a tread strip which is connected with a pair of sidewalls. A runflat reinforcement is arranged at the inner side of each sidewall. A reinforcer is arranged within each bead portion of the tire. A bead filler extends from the bead ring along the reinforcer. To improve the runflat performance, handling and comfort properties of such a runflat tire, the reinforcer is arranged at the inner side of the bead filler. The reinforcer includes metal cords. The bead filler which extends beyond an end of the reinforcer, is made of a soft rubber compound with an IHRD harness lower than 80.
