Tyres account for one tank of fuel out of five, which is why motorists need to make sure they chose the right brand, according to Michelin.
The French tyres manufacturer has detailed how with each rotation of the wheel, a tyre is deformed when it comes into contact with the road.
As its structure is de-formed, the tyre heats up and some of the energy is lost. Reducing this heat build-up makes it possible to lower fuel consumption and, consequently, greenhouse gas emissions.
The tyre-related force that impedes a vehicle’s forward movement is called “rolling resistance”.
Michelin is keen to highlight the issue on the back of the introduction of the new EU tyre labelling legislation which came into effect on 1 November 2012.
The new regulation requires all tyres manufactured after 1 July 2012 to be sold with a label which gives information about their performance in relation to fuel efficiency, wet grip and noise emissions.
According to Michelin, 76% of the European summer passenger car and light truck market is covered by Michelin tyres rated both B or C in energy efficiency and A or B in wet braking.
More than 90% of the European summer passenger car and light truck market is covered by Michelin tyres rated A or B in wet braking.
The tyres in the Michelin Primacy 3 range are rated A in wet braking for all sizes. While tyres in the Michelin Energy Saver+ line are rated either B or C in energy efficiency, depending on their size.
And 100% of summer tyres comply with limits on external rolling noise.
