Could you please provide an explanation of tyre labelling scores? These scores are categorized into three main areas:

• Rolling Resistance The grades range from A to E and indicate the level of fuel efficiency performance. A represents the highest performing tyre in this category, while E represents the lowest performing tyre.

• Wet Grip The grades range from A to E and provide information on the relative performance level of the tyre in wet conditions. A represents the highest performing tyre in this category, while E is used to indicate the lowest performing tyre.

• External Noise The tyre's exterior noise level is measured in decibels (dB) and is represented by one, two, or three sound waves. These sound waves indicate how well the tyre performs in relation to current regulations. Three bars indicate that the tyre meets current noise limits, two bars indicate that the tyre meets noise limits that will be imposed in the future, and one bar indicates that the tyre is even quieter, with a noise level 3dB below future limits.
