The energy lost when a tyre is in motion is known as 'rolling resistance'. This has a direct impact on fuel consumption. A tyre's rolling resistance score ranges from A to G. Over the life of the tyre, fitting an A rated tyre could save you up to 6 litres of fuel when compared to a G rated tyre.
A tyre's wet grip capacity is expressed in Grades from A to G. The difference in braking distances between each grade is roughly 3m - an average car length. This makes average stopping distance between an A and G rated tyre 18m. That's 4 car lengths.
The exterior noise grade of a tyre is expressed in decibels - accompanied by one, two or three sound waves, with one wave being the best noise level performance. To achieve the best grade, a tyre’s noise level must be at least 3dB under the legal limit set by the EU.
Changes to EU Tyre Labelling
Tyre labelling changes will be taking place from the 1st May 2021 in Europe, including in Northern Ireland. To find out more about these changes, click here.
"Wave" pattern with an almost continuous tread block design provides pattern stiffness and water expulsion allowing good cornering and braking performance with reduced risk of aquaplaning.
The tread is designed to improve wet grip, but several reviewers, while praising performance in dry conditions, felt that grip in the wet was only average.
