Retreading tires February 11th, 2009
Are you familiar with the process for retreading tires? The worn tire tread is sanded off and a new tread is applied to the casing. Depending on the tire’s condition, it can be retread up to three times.
A new tire is good for about 120,000 km; retreading can add another 60,000 km to its service life. Better still, manufacturing a bus tire requires almost 84 litres of oil, while retreading one only takes about 27.
Once the tires have exhausted their service life, they are sent to Recyc-Québec, who will make sure they are recycled by all means. And metro tires? Thanks to an STM initiative, the 110 tons of metro tires worn out each year are shipped to rubber recycling plants where they are turned into carpets, and to cement factories who convert them into energy. A small action that goes a long way!
