Some Aspects of High-Speed Tire Testing 570024

THE main emphasis is on the testing of tires for use on high-performance cars, and both indoor and road testing techniques are described. The importance of insuring freedom from “traction wave” or “tread ripple” is stressed.
As the difficulties of road evaluation are greater with high-speed tires, machine testing-methods have been extensively developed and correlated with service performance. These preliminary tests give a good indication of the tire's capabilities before road tests are planned.
The subsequent evaluation of tread life, casing strength, and handling characteristics is illustrated on suitable stretches of Continental roads.
Proving methods for world's land speed record tires and high-speed aircraft tires are included as examples of cases in which almost complete reliance must be placed on indoor testing.
