6. Description of content:  Notice of proposed rulemaking - This document proposes 
amendments to several Federal motor  vehicle safety standards and consumer information 
regulations to update the standard reference test tire (SRTT) used therein. The SRTT is 
used in those standards and regulations as a baseline tire to rate tire treadwear, define 
snow tires based on traction performance, and evaluate pavement surface friction. This 
proposed rule is necessary because the only manufacturer of the currently reference d 
SRTT ceased production of the tire. Referencing a new SRTT ensures the availability of a 
test tire for testing purposes.

applicable:  Prevention of deceptive practices and consumer  protection; Protection of 
human health or safety; Quality requirements
