The basic approach employed in developing J1106 was to consolidate and document existing technology as embodied in equipment and procedures currently employed for routine tire evaluations. Equipment and procedures whose current use is restricted to research applications were not considered. Research experience is discussed in this Information Report, however, to the extent deemed necessary to provide background and rationale for J1106. Material is therefore included on speed effects, contaminants dynamic testing, traction, surface geometry, and other subjects not considered in J1106. The scope was expanded in an effort to anticipate questions raised by J1106.
