Regulation Change Opens Door To Single Wide Tyres in Ontario
An amendment to Ontario’s regulation governing permissible truck axle weight limits has opened the door to single heavy truck tyres. The Canadian province now permits the use of these tyres at the same weights as conventional dual tyres – it is, however, only the second province, after Quebec, to approve this weight parity.
Regulation 435/08 will amend the current weights and dimension regulations to allow wide based single tyres to operate at weights up to 9,000 kilograms per axle and provide flexibility on vehicle track width so that retrofitting can take place. Previously, the Ontario weight threshold for single tyres was 8,000 kilograms per axle on a standard 53-foot tandem trailer.
