Embodiment Construction

[0111] In the following, when the term "radial" is used, it is appropriate for the person skilled in the art to distinguish between the various uses of this word. First, the expression refers to the radius of the tire. This means that point A is said to be "radially inside" point B (or "radially inside" point B) if point A is closer to the axis of rotation of the tire than point B is. Conversely, point C is said to be "radially outside" point D (or "radially outside" point D) if point C is further from the axis of rotation of the tire than point D is. Advancing "radially inward (or outward)" means advancing toward a smaller (or larger) radius. This sense of the term also applies when radial distances are discussed.

[0112] On the other hand, a reinforcing element or reinforcement is said to be "radial" when one or more reinforcing elements of the reinforcement form an angle greater than or equal to 65° and less than or equal to 90° with the circumferential direction.

Abstract

The invention relates to a tire, which includes a knitted fabric (44), including: columns (C1, C2, C3, C4) of loops (B), the loops (B) of a single column (C1, C2, C3, C4) being arranged, one after the other, substantially in a so-called "main" general direction (X1); and rows (R1, R2, R3, R4) of loops, the loops (B) of a single row (R1, R2, R3, R4) being arranged, one beside the other, substantially in a so-called "transverse" general direction (Z1). The knitted fabric (44) has, in the main general direction (X1) and / or transverse general direction (Z1), a force no lower than 250 N when 100% elongated. The force when 100% elongated is determined on the basis of a force / elongation curve obtained by applying ISO standard 13934-1:2013 to the knitted fabric (44) embedded in a standard elastomer matrix.

Description

technical field [0001] The subject of the invention is a tire comprising a braid and a method of producing said tire. Background technique [0002] The invention is applicable to any type of vehicle, but is preferably intended for passenger vehicles, two-wheeled vehicles such as motorcycles or bicycles, industrial vehicles selected from goods vehicles, heavy vehicles such as "heavy duty vehicles" - i.e. subways, coaches, roads Transport vehicles (trucks, tractors, trailers), off-road vehicles, agricultural vehicles or civil engineering installations, aircraft, other transport or handling vehicles. [0003] Passenger vehicle tires are known in the prior art comprising a carcass reinforcement anchored in two beads and radially covered by a crown comprising a crown reinforcement and a tread, The tread is connected to the beads by two sidewalls. [0004] Tire manufacturers are constantly seeking to increase the cornering stiffness of tires to improve tire handling, especially ...
