摘要:
A pneumatic tire (10), has a belt package (14) comprising at least two belt plies (15,16) reinforced by cords (22). The cords have tension vector "b". In each shoulder area of the tire, a strip (18,19) is positioned near the edges (20, 21) of any of the belt plies. Each strip (18,19) is applied in at least one layer, is about 50 mm wide and has an overlap splice so as to have a radially inner and a radially outer end; during tire shaping in the curing mold, each end has a direction of gliding "s". The tension vectors "b" of the belt cords (22) of the belt ply neighbouring the radially inner splice ending form an acute angle with the direction of gliding "s" of the splice ending.

A pneumatic tire (7) is disclosed comprising a reinforcing ply structure (105) extending between a pair of annular bead portions (110); a pair of sidewalls, wherein each sidewall is located radially outward of one of the pair of bead portions (110); a tread radially outward from the reinforcing ply structure; a belt reinforcing structure located radially outward from the reinforcing ply structure and radially inward from the tread; and an innerliner structure (101) extending along an inner surface (106) of the reinforcing ply structure (105) preferably from a position adjacent one bead portion (110) to a position adjacent the other bead portion (110). The innerliner structure (101) comprises a plurality of alternating layers of rubber compound and tire sealant material.
摘要:
The present invention relates to a tire tread (10) comprising a plurality of circumferential grooves (20) separating circumferential ribs, each groove (20) comprising a bottom (21) and two sidewalls (22, 23), and a plurality of laterally separated reinforcements (30), wherein one reinforcement (30) is arranged adjacent each circumferential groove (20), and wherein each reinforcement (30) extends from the radially inner surface of the tread (10) in a radial direction at least to the bottom (21) of an adjacent circumferential groove (20) to form the bottom (21) of that groove (20). Further, the invention relates to a tire comprising a tread (10) in accordance with the present invention.
摘要:
A pneumatic tire comprising an annular tread portion (10) including a plurality of circumferentially extending main grooves (20, 21, 22) comprising an axially innermost groove (22), an axially outermost groove (20), and at least one middle groove (21) arranged between the innermost groove and the outermost groove is disclosed; the outermost groove (20) has an asymmetric cross section with respect to any straight line perpendicular to the groove opening and comprises an inner sidewall (24), an outer sidewall (23), a groove bottom (25) and a groove opening opposite to the groove bottom (25), wherein the outer sidewall (23) is tilted by more than 20°with respect to a straight line perpendicular to the groove opening

摘要:
A pneumatic tire having a pair of spaced apart bead components (6), a connecting carcass (3) between the bead components, a pair of sidewalls (5) overlying the carcass, and a rubber chafer portion (9) adjacent to each of the sidewalls and positioned around at least a portion of each of the bead components and intended for contacting a rigid rim of a wheel is disclosed. At least one of the rubber chafer portions (9) comprises a radially innermost toe guard (9A) and a chafer (9B) adjacent to a radially outer end of the toe guard (9A). The toe guard (9A) has the radially outer end (10) disposed at a sidewall axially outer surface. The ratio of the modulus of elasticity of the toe guard (9A) to the modulus of elasticity of the chafer (9B) is in the range of from 3 to 10.
