The Federal Motor Carrier Safety Administration (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. Petitions for reconsideration of this final rule must be submitted to the FMCSA Administrator no later than March 23, 2026.
