In fact, according to a Quebec, Canada highway safety code regulation that went into effect on December 15, 2014, only tires that meet the 3PMSF standard are considered to be acceptable snow tires for use in Quebec. The law specifies the winter months there as ranging between December 15 and March 15 each year. Winter vehicle requirements may differ by region, so it’s worth familiarizing yourself with what’s legal in your area before you go tire shopping.
While you’ll find many motorcycle tires that bear M+S designation, the Anlas Winter Grip Plus is one of the only (if not
the only) motorcycle tires with a 3PMSF rating as of January 2022. "
