... The transportation of people and goods on the world's roadways depends on rubber. In this review, the tires are discussed in terms of the relationships between rubber properties and tire performance. The tire not only carries a load, but also transmits forces to steer, accelerate, and brake...

... Two field trials were constructed to investigate the effect on water quality of tire chip fills placed above the groundwater table. Control wells were used to distinguish the substances naturally present in groundwater from those that leached from tire chips. There was no evidence that tire...

... The ability of ground tire rubber to sorb BTEX compounds from groundwater was examined. The current study consisted of running both batch and packed bed column tests to determine the sorption capacity, the flow through utilization efficiency and the reversibility of BTEX sorption to ground tire...

... In support of efforts by the Ontario Ministry of the Environment to dispose of waste tires, the Ontario Ministry of Transportation built a demonstration hot mix pavement incorporating waste tire rubber at Thamesville, Ontario, in 1990 and 1991. The purpose of the demonstration was to confirm...

... A method is developed for measuring small changes in rolling resistance between different types of bicycle racing tires. The method described has been used specifically to assist in the choice of tires to be used on a special-purpose vehicle entered in an event where the aim is to use the least...

... In this paper, methods currently in use to measure tire-pavement friction are reviewed. The emphasis is on full-scale measurement systems operated at highway speeds, including systems that measure brake force coefficients (under slip or lockedwheel conditions or both) and side-force coefficients...

... Previous National Aeronautics and Space Administration (NASA) Langley aircraft tire friction performance investigations indicated the primary parameter influencing dynamic tire hydroplaning was inflation pressure. The empirical equations derived from aircraft tire test data to estimate tire...

..., but never more than two days. During the study period, 79 such sites were tested, 21 of which had multiple accidents. All sites were tested with the ribbed and blank test tires. Similar tests were made on control sections within 1.6 km (1 mile) of the accident sites. These were selected to have geometric...

... Between the tread of the tire and the road there are distributions of interfacial pressure and horizontal stresses that affect many of the important operating properties of pneumatic tires. Among these are traction, treadwear, steering forces, noise generation, power loss, and envelopment...

... The National Tire Modeling Program is a joint National Aeronautics and Space Administration (NASA) - industry effort to improve the understanding of tire mechanics and develop accurate analytical design tools. This effort includes fundamental analytical and experimental research...

... Diagonal wear on tires is a significant problem that can cause noise and vibration, and reduce the useful life of the tire. A wear model is used to show how diagonal wear can develop across the tread under certain conditions of toe and camber on a nondrive axle. In a simple wear model, tread...

... The tire/pavement interface zone is the origin of a major portion of the ride vibration, ride noise, and environmental noise disturbances associated with road vehicles. It is appropriate to view these separate problems as one comprehensive systems problem involving the road, the tire...

... tester used at Owens-Corning Fiberglas Corp. is described, with examples of test programs in which the instrument capabilities were utilized to simulate the impact forces on boat, pipe, and tire constructions. Modifications made to the ram, or mode of operation, better simulate end-use conditions...

... Meaningful assessment of tire wet traction performance requires an understanding of the tire use environment. The important factors are tires, rainfall conditions, roads, vehicles, and vehicle operation. Analysis shows that certain combinations of these factors are frequently associated...

... The reduction in wet skidding resistance with reduced tire tread pattern depth on road surfaces possessing low macrotexture is well understood. With the dominance of radial tire construction, with its inherently higher abrasion resistance, automobile tires are often observed to be removed from...

... Traction testing of passenger car and truck tires in adverse environments (snow, ice, mud, and sand) has become an increasingly important segment of most new tire development programs. This increased emphasis is due to the continued refinement of the all-season design, consumer desires for more...

... This paper analyzes the general requirements of antilock brake systems in decreasing vehicle stopping distance and maintaining directional control during braking. The dual phenomenon of tire slip and vehicle dynamic weight transfer, which necessitate the use of antilock systems for high...

... A rig has been designed and built for the on-road measurements of rolling resistance and bearing friction losses for free-rolling tires of large trucks. The rig comprises a force bridge, axle, suspension, and two sets of dual wheel assemblies mounted on a 13.7-m (45 ft) flatbed trailer which...

... An interactive tire-fluid model has been developed to serve as an aid in understanding dynamic hydroplaning of pneumatic tires. Dynamic hydroplaning occurs when the amount of fluid encountered by the tire exceeds the drainage capacity of the footprint region. The tire is completely separated...

... A comprehensive series of experiments is reported involving a variety of full-scale highway pavements and various automobile tires. Test condition variables include vehicle speed, tread depth, water depth, and pavement inundated length. Extensive test data are shown which define the tire forces...
