1. Wet Grip
Secure grip in wet conditions is crucial for safe driving. The wet grip rating indicates how well the tire will perform in wet conditions, with performance graded from class A down to E. A high grade means short braking distances on wet roads.
2. Fuel efficiency
Depending on the tire’s rolling resistance, its fuel efficiency will range from class A (denoting the best fuel economy) all the way down to class E. Fuel consumption plays an important role from an economic and ecological point of view. This is because low fuel consumption has a positive effect on the carbon footprint of the vehicle, and of heavy-duty vehicles in particular.
3. Noise Level
This is the external rolling noise generated by the tire, measured in decibels. The label shows the noise level rated in classes from A down to C.
In addition to the standard label, there are also pictograms − if applicable − relating to performance in severe snow conditions (3PMSF) and/or grip in icy conditions (passenger car/C1 tires only).
The snow grip pictogram (3PMSF) will be shown for winter and all-season tires tested under defined winter conditions and that deliver the required severe snow performance.
The ice grip pictogram will be shown for winter tires with outstanding ice performance confirmed by a defined ice grip test. These tires are specifically designed for road surfaces covered with ice and compact snow, and should only be used in very severe climate conditions (e.g. cold temperatures in the Nordics). Using ice grip tires in less severe climate conditions (e.g. wet conditions or warmer winter temperatures) could result in suboptimal performance, in particular for wet grip, handling and wear.
How is rolling resistance linked to fuel efficiency?
As your tyres rotate, they also flex towards and away from the surface of the road, leading to a loss of energy. The amount of energy lost correlates with the rolling resistance of the tyre.
Tyres with low rolling resistance are the most energy efficient. That means it takes less power – and therefore less fuel – to move the vehicle.
Since tyres can account for between 20% and 30% of a vehicle’s fuel consumption, choosing new tyres that are energy efficient will result in direct fuel cost savings.
Tips for efficient driving
For improved fuel efficiency and greater road safety consider the following factors:
- Environmentally aware driving can reduce fuel consumption significantly;
- Check your tyre pressures regularly; low pressure increases fuel consumption and affects braking performance;
- Always maintain a safe distance from the vehicle in front;
- Check for signs of uneven wear on the tyres, especially along the edges of the front tyres. Uneven wear could indicate a tracking or suspension problem that could increase fuel consumption and cause your tyres to wear more quickly;
- Avoid harsh acceleration and deceleration; this increases both fuel consumption and tyre wear;
- Follow the vehicle manufacturer’s maintenance recommendations;
- Extra weight increases fuel consumption; regularly clear out non-essential items from your car.
