Description / Abstract:
1. Scope--This SAE Recommended Practice defines the best known
techniques for evaluating dynamic passenger car and light truck tire
driving traction in snow. There are many snow conditions which a
typical driver will encounter that are not specifically addressed in
this Recommended Practice. Dynamic driving traction in this Recommended
Practice is under a narrow, controlled range of conditions of
temperature, snow compaction and depth (commonly called the "Test
Window") to minimize test variability. Tire rankings may differ on
other types of snow and ice conditions.
1.1 Object--The object of this SAE Recommended Practice is to provide a
uniform test procedure for measuring the dynamic driving traction of
passenger car and light truck tires in snow.
