Parts and Accessories Necessary for Safe Operation; Tire Load Markings

FMCSA proposes to revise the requirements for tires on commercial motor vehicles (CMVs) to clarify that the Federal Motor Carrier Safety Regulations (FMCSRs) do not require tire load restriction markings on their sidewalls. This change would eliminate confusion and clarify the scope of FMCSA's authority regarding the requirements for tires in the FMCSRs.
