A test campaign was conducted where a tire pressure monitoring system (TPMS) was installed on seven identical Class 8 tractors, to assess the benefits of the system as well as its accuracy and reliability in Canadian environmental conditions. Data were collected through driver and mechanic checklists as well as telematics. Three identical tractors were also included as a control group. Approximately 3.7 million test kilometres were accumulated over a one year period, with the tractors performing weekly trips between Canada and the United States. Only two tire incidents were experienced, where the damaged tires were replaced in a timely manner without any highway incidents. There was no noticeable difference in treadwear or fuel economy between the test and control trucks, but this would likely have been affected by the proactive maintenance and inspection schedule followed by the fleet. The TPMS proved to be accurate and reliable. The drivers and fleet management staff were surveyed at the end of the test campaign and they both provided positive feedback – they recommended the use of such a system on all tractors and trailers.
