Under-inflated tires rolling on Canadian roadways waste enough fuel to power 275,000 vehicles for a full year.
Canadian motorists suffering from sky-high fuel prices may be adding to their pain by not measuring their tire pressures monthly.
Canadian drivers will waste an estimated $722 million in unnecessary fuel bills in 2011 simply because one or more of their tires are under-inflated, according to data from Natural Resources Canada and the Rubber Association of Canada (RAC), which represents tire makers.
