摘要： PROBLEM TO BE SOLVED: To reduce rolling resistance and heat accumulation by using an insert containing setting polydiene rubber connected by a metal of the IVB group including tin, lead, germanium and silicon, a filler within a specific pts.wt. range, and fatty acid within a specific pts.wt. range. SOLUTION: A substantially crescent insert 12 is arranged in parallel in at least one of carcass plys 10 in a side wall 3 of a tire so as to be inserted into the axis inside. The insert 12 contains setting polydiene rubber connected by tin, lead, germanium or silicon, about 30-130 phr (pts.wt. per 100 parts of rubber) of a filler, and about 0.1-5 phr or fatty acid. The insert 12 using this composition provides a higher level modulus, to reduce its thickness. In this way, accumulation of heat and a level of a hysteresis can be lowered to reduce rolling resistance and accumulation of heat.

摘要： PROBLEM TO BE SOLVED: To provide a tire for an ATV maintaining a flexible tire characteristic and having an excellent run flat characteristic without requiring a special rim. SOLUTION: A carcass 30 extended toward a circular bead core 26 and surrounding the periphery of the bead core 26 is provided on the inside in the radial direction of a circular tread 12. An elastomer apex 48 is extended to the outside in the radial direction from the bead core 26 in adjacent to the bead core 26. An elastomer insert 42 is extended to the inside in the radial direction and the axial direction of the outside portion in the radial direction of the apex 48 toward the bead core 26 to the inside in the radial direction from the edge of the tread 12.

摘要： A runflat radial ply passenger or light truck pneumatic tire 10 has a carcass 30 reinforced with at least one sidewall insert or filler 42 and one substantially inextensible cord reinforced ply 38, the ply being wrapped about two bead cores 26 and located radially inward of a belt reinforcing structure 36. The sidewall insert or filler 42 is located radially inward of the ply 38. The cord 43 has a minimum modulus E of 10 Gpa and is generally inextensible and less heat sensitive than conventional synthetic cords used in passenger and light truck tires. In one embodiment the ply cords 43 are aramid in another embodiment the cords 43 are steel

摘要： A run-flat radial ply pneumatic tire (10) having a carcass (30) reinforced with elastomeric sidewall fillers (42,46,48) and at least three bead cores (26,26') and (37) is disclosed. At least one bead core (37) extends radially inwardly of the tread (12) and one or more reinforcing belts (36). The tire (10) made according to the invention can exhibit equal to or improved ride over conventional tires while also providing a limited run-flat capability. In several preferred embodiments improved wet traction tread configurations are employed.

摘要： The invention relates to a run-flat low inflation pressure all terrain vehicle (ATV) tire 10,11, wherein the tire 10,11 has at least one pair of elastomeric inserts 42,46, one insert 42,46 extending radially inward from each tread edge 14,16 toward a bead core 26. The radially inner end of the insert is radially inward of an elastomeric apex 48 located above the respective bead cores 26. The bead cores 26 have a wide substantially flat radially inner base which when the tire 10,11 is mounted on a conventional ATV design rim enable the tire 10,11 to remain seated onto the rim even when operating without any inflation. The preferred tire 10,11 has a unique tread 12. The central portion 13 of the tread 12 has circumferential rows of blocks or lugs 94. The lugs of laterally adjacent rows in a central region 13 of the tread 12 are connected by tie bars 93 which when employed on these run-flat tires keeps the tread lugs 94 in ground contact even when the tire is operated uninflated. The inventive tire 10,11 can be constructed providing limited run-flat capability or with a full run-flat capability never requiring air inflation during use.

摘要： A low pressure all terrain vehicle tire 10 features a strapped bead core 20 which comprises distinct layers 30,32,34,36 of filaments 26 positioned relative to one another. The bead core 20 has a substantially square or rectangular cross-section and a radially inward substantially flat base side 44, a radially outermost side 46, an axially inward first side 48, and an axially outward second side 50. The first side 48 intersects the base side 44 at a first edge 54 and forms thereby an included angle alpha . The second side 50 intersects the base side 44 at a second edge 56 and forms thereby an included angle beta . Angle alpha is equal to beta . The bead core 20 has perimeter 42 comprising the lengths of the base 44, radially outermost 46, first 48, and second 50 sides. The perimeter 42 defines the bead core area. The width of the bead heel surface 60 is approximately equal to the distance between a hump 80 and an axially inward surface 74 of the wheel flange 76. The bead core base side 44 has a width in the range of 65% to 90% of the rim seat width W and a radially inner diameter about equal to the diameter of the rim hump 80. The bead heal surface 60 has a width in the range of 80% to 125% the rim seat width W.

摘要： A runflat radial ply pneumatic tire (10) having a carcass (30) reinforced with at least two sidewall fillers or inserts (42, 46) and at least one cord reinforced ply (38) and two bead cores (26) and one or more reinforcing belts (36). The at least one ply (38) reinforced with cords, the cords have a pair of turnup ends (32) wrapped around the pair of bead cores (26). The turnup ends (32) extend radially outwardly to a terminal end (33), the terminal end (33) being located under the reinforcing belts (36). The first insert (42) lies radially inward and adjacent the ply (38). The second insert (46) lies radially between the ply (38) and its turnup end (32). The tire (10) requires a reduced number of components and can be lighter in weight than the prior art runflat tires.
