While fuel - efficient tires are n’t anything raw , they are new at your local tyre store . Manufacturers have long installed tires that would improve fuel efficiency ratings on new gondola , but machine owner look for those same fuel - saving tire when it came time to replace the originals were out of luck . tyre shops did n’t trade them . These days , tire manufacturers realise that consumer are just as interested in get good gas gas mileage as auto makers are with draw good miles per gallon military rating from the Environmental Protection Agency ( EPA ) .
Tires with a low - roll - resistance are now widely available for most passenger vehicle . Rolling resistanceis the measure of " forcefulness at the axle in the direction of travel required to make a pie-eyed tire roll , " accord to a report by the National Research Council ( NRC ) . That ’s a precise means of say that pealing - resistance measure how much elbow grease the automobile has to put into name the tires seethe along the pavement . Tires with low-pitched trilled resistance use stride design and new materials to minimize the amount of energy , in the strain of gasoline , required to move the car .
Fuel - efficient tires can be a minute more than standard tires , but they can also reduce the amount of gasoline needed by 6 pct . At this rate , the gas savings could yield for the bounty on fuel - saving tires in about one year [ source : Treehugger ] .
A National Research Council paper on tires and fuel economic system says that a 10 percent simplification in rolling resistance increased fuel economic system by 1.5 percentage , even during stop - and - go drive . For highway driving , that same 10 percentage humiliated trilled resistance meant 2.1 percent better fuel saving [ source : National Research Council ] .
Major tire manufacturer like Michelin , Cooper , Goodyear and Continental all offer fuel - saving , down - wheeling - resistance tires these days . throw these tires useable to the consumer means we can all keep our car ’s fuel consumption rate closer to the EPA fuel economic system estimates – and maybe even do a little good .
