A precured tread assembly for mounting on a tire casing is provided. The precured tread assembly includes a tread portion having a mounting surface and an opposing ground-engaging surface with a plurality of grooves therein. A reinforcing fabric layer is attached to the mounting surface of the tread portion.

The invention provides for a heavy truck tire having a sub-casing, a belt package and a rubber tread, the tread comprising a center zone separating two shoulder zones. The upper shoulder layer consisting of an upper shoulder rubber compound being different from a lower shoulder rubber compound, wherein: the upper shoulder rubber compound has a G*50 of at least 1.3 Mpa and a max tan(δ) of at least 0.12; the lower shoulder rubber compound has a max tan(δ) not greater than the max tan(δ) of a center rubber compound in the center zone being intended to come into contact with the ground; and the center rubber compound has a max tan(δ) of at most 0.09.

This disclosure relates to a system and method for determining responsiveness of a driver of a vehicle to feedback regarding driving behaviors. The system may include a sensor configured to generate output signals conveying first driving behavior information, which may characterize operation of the vehicle by the driver. The system may include one or more processors configured to obtain the first driving behavior information. The one or more processors may effectuate provision of feedback defined by feedback information based on the first driving behavior. The sensor may be configured to output signals conveying second driving behavior information, which may characterize operation of the vehicle by the driver during and/or subsequent to the provision of the feedback. The one or more processors may be configured to obtain the second driving behavior information and assess responsiveness of the driver to the feedback based on the second driving behavior information.

Disclosed are a hybrid fiber cord comprising a nylon filament and an aramid filament, the cord having more uniform physical properties and better strength and fatigue properties and being able to be made more easily than the conventional hybrid fiber cords such that it can be used to make an ultra high performance tire, and a method for manufacturing the same. The hybrid fiber cord comprises a nylon primarily-twisted yarn having a first twist number, and an aramid primarily-twisted yarn having a second twist number. The first twist number is identical with the second twist number. The nylon and aramid primarily-twisted yarns are secondarily-twisted together to have identical structures with each other.

Various implementations of an occupant detection system may be used in a vehicle to detect the presence of a living occupant (human or otherwise) and generate a warning. The warning may be communicated to another person(s) or to other vehicle systems to alert people in the vicinity of the vehicle. The system prevents injury and death to people and pets that may be accidentally within a parked car and unable to egress. The system may be integrated into a new vehicle or housed in a separate device that can be plugged into a power outlet within the vehicle.

An aramid textile cord (50) with at least triple twist (T1, T2, T3) comprises at least N strands (20a, 20b, 20c, 20d), N being greater than 1, twisted together with a final twist T3 and a final direction D2, each strand being made up of M pre-strands (10a, 10b, 10c), M being greater than 1, themselves twisted together with an intermediate twist T2 (T2a, T2b, T2c, T2d) and an intermediate direction D1 opposite to D2, each pre-strand itself consisting of a yarn (5) which has been twisted on itself beforehand with an initial twist T1 (T1a, T1b, T1c) and the direction D1, in which at least half of the N times M yarns are aramid yarns. This textile cord can advantageously be used as a reinforcer in tires for vehicles, particularly in the belt or carcass reinforcement of these tires.

A pneumatic radial tire includes belt layers disposed on an outer circumferential side of a carcass layer in a tread portion. The belt layers are formed of steel cords in a N+M structure in which the number of wire strands N of an inner layer is 2 to 4 and the number of wire strands M of an outer layer is 2 to 7. A twist direction of the inner layer is different from a twist direction of the outer layer. The steel cords are inclined with respect to a tire circumferential direction to intersect each other in layers of the belt layers. A belt cover layer disposed on an outer circumferential side of the belt layers is formed of organic fiber cords having elongation of 2.0% to 4.0% under 2.0 cN/dtex load. The organic fiber cords are wound spirally along the tire circumferential direction.

Information relating to a change made to a concrete mixture in a concrete mixer truck is obtained. An expected value of a selected characteristic of the concrete mixture is determined based on the change. A representation of the expected value is displayed on a processing device located in a cab of the concrete mixer truck. In one embodiment, the mixture comprises a concrete mixture. The change may comprise an addition of water to the mixture.
