Abstract
This paper is intended to show that tire engineering is not concerned merely with improvement of quality, but also is concerned, on the part of engineers, with information on the friction phenomena in the boundary layer between the tire tread and the road surface. For a tire to have good abrasion properties, the resistance of the tread should be high and the work of friction should be as low as possible. Methods for measuring the work of friction are described, with some examples of influences which have control over it. While at the present stage of progress in technical developments, improvement of the resistance to abrasion of tire treads and in the design of treads is limited to small percentages, external conditions in service may increase the work of friction several fold. This accounts for common wide differences in the life of similar tires on the road. It is hoped that this paper may lead to further cooperative research on phenomena at the boundary surface between the surface of a tire and of the road. Such studies would be in the interest of the rubber industry, the automotive industry, and the consumer.
