Docket No. FMCSA-2025-0123
Abstract
FMCSA amends the requirements for commercial motor vehicle (CMV) tires to clarify that the Federal Motor Carrier Safety Regulations (FMCSR) do not require tire load restriction markings on the sidewalls of the tires. This change eliminates confusion and clarifies the scope of FMCSA's authority regarding requirements for CMV tires.
