The proposed Regulations are based on the text of the MVTSR 1995, but changes were made to improve clarity and internal consistency, to be consistent with current legal drafting practices, and to enable Technical Standards Document (TSD) alignment with the U.S. tire safety standards through the incorporation by reference of TSDs.
The proposed Regulations would introduce most of the requirements of U.S tire safety standards Federal Motor Vehicle Safety Standard (FMVSS) 109, 119 and 139 into Technical Standards Document No. 109, New and Certain Specialty Tires; Technical Standards Document No. 119, New Tires for Motor Vehicles With a GVWR of More Than 4 536 kg and Motorcycles and Technical Standards Document No. 139, New Radial Ply Tires for Motor Vehicles With a GVWR of 4 536 kg or Less, respectively.
Consequential amendments to paragraph 120(2)(c) of the Motor Vehicle Safety Regulations (MVSR) would be necessary, since this paragraph references the MVTSR 1995. Also, Schedule III of the MVSR includes the Canadian Motor Vehicle Safety Standards (CMVSS)
110 and 120. These two safety standards specify tire and rim selection requirements and rim marking requirements. CMVSS 110 and 120 incorporate TSDs 110 and 120, respectively. Amendments would also be made to TSDs 110 and 120 since they make reference to various subsections of the MVTSR 1995.
The proposed Regulations would align the Canadian and U.S. tire testing and marking requirements. It is anticipated that this would reduce the cost and complexity of product testing for tire and vehicle manufacturers, while improving safety for Canadians.
