Environment Canada Sponsor a Tire Clinic Over 100 motorists attended Environment Canada's tire clinic at their Downsview regional office on June 3, 2004. The day included a tire information presentation and a tire clinic where attendees had their tire pressure measured. Motorists were also shown the location of their vehicle's information placard, to help them determine the appropriate tire pressure for their vehicle. Participants learned that being "tire smart" is a great way to help reduce greenhouse gas emissions and reduce fuel consumption.
