LAVAL, Quebec—The province of Manitoba has adopted regulations that facilitate “load parity,” a move that allows wide-base single heavy-duty truck tires to operate at the same weight limits and payload as conventional duals, according to Michelin North America (Canada) Inc.
Manitoba is just the third Canadian province to adopt load parity, Michelin said. Quebec adopted the practice in 2006 and Ontario in 2008.
In Manitoba, the 2015 revised regulations apply to trucks traveling provincial highways that meet national load ratings, known as Roads and Transportation Association of Canada highways, Michelin said.
In all instances, the provincial regulatory changes were implemented after extensive consultations with the trucking industry.
Michelin claims the use of wide-base singles—such as the Michelin X-One line produced at its Waterville, Nova Scotia, plant—in place of dual fitments yield measurable gains in payload capacity while offering reduced fuel consumption and greenhouse gas emissions.
