Lowering car emissions with EU tyre labels
At this point in time, due to the UK no longer being part of the EU, the application of the new EU Tyre Label regulation in UK law is not yet confirmed by the DfT.
The current indication is that this will not be before the end August, and that both old and new labels will be accepted until it is ratified in UK law.
This is subject to change and we will provide an update once firmer details are available.
Your tyres rotate as you drive down a road, flexing towards and away from the surface of the road; this leads to a loss of energy. The amount of energy lost correlates with the rolling resistance of the tyre.
Tyres that have a low rolling resistance are the most energy efficient. That means less power – and therefore less fuel – is required to move the vehicle.
Since tyres can account for between 20% to 30% of a vehicle’s fuel consumption, choosing new tyres that are energy efficient will result in direct fuel cost savings.
Critical for driving safety is a secure grip in wet conditions. The wet grip rating indicates how well the tyre will perform in wet conditions, with performance graded between class A and class G (although D and G are not currently in use). In general, the EU label assumes a speed of 80 km/h. Braking at this speed, a class A tyre will come to a stop in wet conditions after 28 metres. By comparison, a class F tyre requires 46.5 metres to come to a stop, giving a difference of more than 18 metres. From a safety point of view, it makes sense to opt for a higher-class tyre.
Depending on the tyre’s rolling resistance, its fuel efficiency will range from class A (denoting the best fuel economy) all the way through to class G (delivering the worst fuel economy). Between classes, fuel consumption increases by approximately 0.1 litre for every 100 km driven.
Noise level is the external rolling noise generated by the tyre, measured in decibels. The number of filled sound waves on the label equates to the noise level of the tyres. A single sound wave means that the tyre has the lowest noise level, between 67 and 71 dB. The highest level is represented by three sound waves, which is between 72 and 76 dB.
Actual fuel efficiency and road safety depend significantly on the behaviour of the motorist. In particular, consider the following factors:
