Tires’ substantial environmental footprint is set to drop as producers increase their use of renewable materials and efficient technologies emerge for chemically recycling them. Currently, most tires are incinerated or landfilled, at a high price. While the sector’s may be shrinking, millions metric tons rubber particles get released annually wear down on roads. And independent scientists say t...

From a traffic safety perspective it is highly motivated to define winter tires in terms of their performance in icy road conditions. The present definition of winter (snow) tires, introduced in the EU in 2012, is based on packed snow performance. The present paper investigates the feasibility of an indoor winter tire classification test on ice. Results presented here indicates that a test proc...

In the material handling business original equipment manufacturers, lift truck dealers and distributors find themselves marketing polyurethane and rubber tires simultaneously. To achieve optimum performance one needs to better understand the attributes of each product. In this article, both products will be broadly compared along with their proper application, with an emphasis on polyurethane t...

A scenario of an automotive accident caused by tire failure is given followed by a human factors analysis of the information available to consumers on tire aging. Consumers have not been told that the age of the tire is a safety concern. It is not easy to decode the date of manufacture on tires. More publicity and prominent warnings are needed to communicate the dangers of older tires. Also, be...

The nonlinear free vibration for viscoelastic cross-ply moderately thick laminated composite plates under considering transverse shear deformation and damage effect is investigated. Based on the Timoshenko-Mindlin theory, strain-equivalence hypothesis, and Boltzmann superposition principle, the nonlinear free vibration governing equations for viscoelastic moderately thick laminated plates with ...

For brittle fracture behaviour of carbon fibre reinforced plastics (CFRP) under compression, several approaches exist, which describe different mechanisms during failure, especially at stress intensifications. The failure process is not only initiated by the buckling fibres, but a shear driven fibre compressive failure beneficiaries or initiates the formation of fibres into a kink-band. Startin...

Not all professional astronomers use observatories to ply their trade. Some are hard at work in the laboratory, unraveling the mysteries of the universe. } { CHRIS SCHUR

This article studies the influence of speed a car with low and ultra-low profile tires, 14ʹʹ 16ʹʹ, negotiating turn through an interactive software system developed by us in MATLAB environment. The changes normal lateral loads wheels are obtained characteristics side slip angle (known as slip) pneumatic tires determined. Taking into account wheels, determines center turn. for both types given. ...
