摘要:
A tire breakdown warning device includes at least one temperature sensor for detection of temperature of a pneumatic tire, and provides a warning when a breakdown of the tire is found on the basis of detection signals detected by the at least one temperature sensor. The at least one temperature sensor is embedded in the vicinity of at least one end of at least one tire constituent component which is placed in the pneumatic tire and which is vulnerable to break down.

Provided is a method of fitting a tire-and-wheel assembled body to an axle, which is capable of resolving imbalance in a state of fitting an assembled body including a tire and a wheel to an axle. In this fitting method, a tire is fitted to a wheel, and then core positions of fastening holes are, or a core position of a hub hole is, adjusted in the wheel to minimize an amount of eccentricity of an assembled body including the tire and the wheel.

摘要:
A pneumatic radial tire for passenger cars having a plurality of grooves formed in the tread and extending at least circumferentially of the tire, the tread being provided with two belt plies therein in such a manner that their belt cords extend in a crisscross pattern. The grooves have a depth in the range of 6.0 to 8.5 mm, with the thickness of the under-groove rubber layer from the bottom of the grooves to the outer belt ply being fixed within the range of 0.5 to 2.0 mm. The belt plies are placed one over another with the both edge portions left unfolded. At least one of the plies is made from aramid fiber cords and at least the both edge portions of the belt plies are covered with at least one belt cover ply which has a cord angle of no greater than 30 deg with respect to the circumference of the tire. The belt cover ply is made of organic fiber cords no larger than 0.7 mm in diameter at a picking density of 35 to 90 percent.
摘要:
Pneumatic radial tires for automotive use are constructed with a belt layer reinforced with a steel cord of a unique structure. The steel cord results from the preformation of a single steel wire into a spiral shape meeting specified spiral parameters as determined by specified spiral diameters, specified wire diameters and specified spiral pitches. Significant weight saving is attainable with sufficient driving performance.
