Abstract:
The invention includes tire treads, tires including the tire treads, and methods of forming a tire tread. The tire tread includes a length extending in a lengthwise direction, a width extending in a lateral direction, and a thickness extending in a depth-wise direction from an outer, ground-engaging side of the tread. The tire treads further include a sipe having a length, a height, a width, a thickness extending in a direction of the sipe width, and a cross-section taken along a plane extending in a direction of the sipe width and height, where the cross-section twists as the sipe thickness extends along the length of the sipe. Method of forming the tire tread includes molding into the tread a sipe and a void feature as recited herein.
Abstract:
System state indicator in particular for a vehicle dashboard, the system having a given use potential and comprising evaluation means such that, on the basis of measurements related to the conditions of use of the vehicle and/or the physical characteristics of the system and/or the vehicle and/or the vehicle environment conditions, the evaluation means calculate at a time t parameters characteristic of the state of the system, characterized in that the state indicator simultaneously displays at time t at least three different parameters characteristic of the state of the system and its range.
Abstract:
The present invention includes tire treads having a sipe (18) and a void feature (22) in fluid communication with the sipe. Particular embodiments of the present invention also include methods for forming the same. In various embodiments, the sipe has a length, a height, and a thickness that is variable across the length and height of the sipe. The thickness of the sipe includes a thick portion (24) and a thin portion (26), the thick portion at least partially extending around a perimeter of the thin portion. In particular embodiments, the void feature (22) which is in fluid communication with the sipe extends primarily in a direction of the sipe length and has a width extending in the direction of the sipe thickness equal to or greater than substantially 1 millimeter.
Abstract:
A centralized device for dealing with the phenomena of loss of pressure and running flat with a vehicle tire, including a means external to the mounted assembly, permanently fixed to the vehicle and able to inject or otherwise bring into the internal cavity of the tire at least one active product, also external to the mounted assembly, and able to treat the phenomena of loss of pressure and ultimately running flat.

Abstract:
The invention concerns a light safety support (1) for a tire comprising a base (2), a top (3) and an annular linking body (4) with a continuous support element around the circumference and a circumferential median plane, wherein the support element includes a plurality of partitions (13), (23) extending axially on either side of the circumferential median plane that are adapted in their central part relative to their lateral end parts to reinforce the support buckling strength under a radial load.
Abstract:
Tire tread including one or more tread elements arranged between a pair of discontinuities extending in a direction of the tread width. The first and second longitudinally-spaced sides of the tread element are spaced-apart in a direction of the tread length. The first longitudinally-spaced side is oriented at an average first-side angle relative to the depthwise direction of the tread and the second longitudinally-spaced side is oriented at an average second-side angle relative to the depthwise direction of the tread. An average inclination angle comprising a combined average of the average first side-angle and the second side-angle for all of the one or more tread elements along the first and second longitudinally-spaced sides is substantially greater than zero.
Abstract:
A safety insert designed to be mounted in an assembly comprising a tire and a rim of a vehicle and device for detecting the bearing of the tire on an insert, so that the insert generates signals oriented parallel to the axis of rotation of the tire and rim assembly and so that the device detects and analyzes the vibrating signals of the chassis of the vehicle.

Abstract:
A method of testing a run-flat tire component is provided. In one exemplary embodiment, the method includes positioning a run-flat component upon a wheel, accelerating the wheel to a predetermined speed, decelerating the wheel to a stop, and determining any rotation of the run-flat component relative to the wheel.
