The tyre label
Explanation of the tyre label
All new tyres are issued with a label, which represents a performance index in 3 sectors. One of the characteristics expressed by the tyre label (or sticker on tyres for passenger vehicles and light trucks) is rolling resistance (= fuel consumption). These categories range from A (low) to G (high). The tyre label also features information about grip on wet road surfaces (= safety), which is also categorised from A to G, and the external noise created by the tyre, expressed as a certain value. The label allows users to select efficient and safe tyres based on fuel consumption, grip and environmental burden.
What do the icons mean?
The tyre label is based on a European directive aimed at improving road safety, reducing fuel consumption and CO2 emissions, and reducing noise produced by road-based traffic. What do the three icons mean:
Rolling resistance
There are 7 classes (A to G), which indicate a difference of 7.5% between the highest (A) and the lowest (G) class. There is thus a difference of 7.5% in fuel efficiency between A and G because each of the categories has a particular rolling resistance. The efficiency potential per class is between 0.10 and 0.15 l/100 km. *
Grip on wet road surfaces
There are 7 classes (A to G) representing a difference of ≥ 30% in braking distance between A and G. This amounts to ≥ 18m at 80 km/h. The difference between A and B is 3 to 4m; 4 to 5m from B to C; 5 to 6m from C to E and over 6m from E to F; categories D and G are not used.
External rolling noise
Noise production is represented using 3 ‘waves’. 3 waves = 2001/43: current norm; 2 waves = 661/2009: between the future norm (2016) and 3dB below it; 1 wave = over 3 dB below the future norm. **
* Tyres must comply with minimum performance limits in order to be permitted to the European market. No longer permitted since 1-11-2014: tyres with a Rolling resistance of G and a Grip on wet road surfaces of F.
Exceptions:
- Renewed tyres.
- Professional off-road tyres.
- Tyres only designed for assembly on vehicles registered for the first time before 1-10-1990.
- T reserve wheels for temporary use.
- Tyres for speed category under 80 km/h.
- Tyres with a nominal rim diameter of maximum 254 mm (10 inches) or minimum 635 mm (25 inches).
- Tyres with features that improve traction (e.g. studded tyres).
- Tyres only designed for assembly on vehicles used solely for racing purposes.
** Passenger vehicle tyres: norm per section (classes); tyres for vans and trucks: norm per category.
New criteria added
The European tyre label was introduced in 2012 and has now been improved. As of 1 May 2021, when the new label becomes mandatory, you will be able to make better choices based on heightened awareness and several new criteria: mileage, wear resistance and grip on snow and ice. Furthermore, from 1 May 2021, the tyre label will also apply to heavy commercial vehicles, which do not have a label at present.
From a visual perspective, you will be able to easily recognise the new version of the European tyre label. For instance, it is based on the EU energy label, which is used to assess a variety of electrical appliances. The original pictograms will be retained.
Improved energy efficiency
According to the Commission, the new rules will result in energy savings that are equivalent to 4 million fewer cars on the EU's roads. That's why Miguel Arias Cañete, EU commissioner for Energy and Climate Action, is delighted with this initiative: "Energy efficiency also applies to the way in which we drive. By switching to the most energy efficient tyres, European citizens and companies can significantly reduce their fuel consumption, while saving money and helping the environment. This is part of Europe's approach to genuine energy security and climate protection".
Select suitable tyres for your situation even faster
The main advantage of the new label is that it allows you to select suitable tyres for your specific situation even faster and more efficiently than before. In addition, you do not have to do anything once the new legislation comes into effect. We will make sure that the information needed for our whole range is accurate and freely available.
Save money with ‘green’ tyres
The better the label (thus lower classifications), the greater the efficiency benefits in practice. The German institute TüV supervised practical research at synthetic rubber manufacturer Lanxess, which led to some surprising conclusions. For instance, a tanker featuring ‘green’ B-label tyres realised a saving of 8.5%, over a distance of 40,000 km, compared to an identical tanker featuring standard tyres from category D.
Example demonstrating benefits for transport companies:
Here is a sample calculation: a transport company with a fleet containing 300 40-tonne trucks, featuring tyres with a rolling resistance of D on the European tyre label, will be able to save 1.5 million euros in fuel per year by selecting tyres with a B label. Assumption: each vehicle drives 150,000 kilometres per year and fuel costs 1.40 euros per litre. In this example, the reduction in CO2 would amount to over 3,000 tonnes per year.
What is the main purchasing criterion?
Fleet managers and owners of transport companies often base their purchases on
- life-span in kilometres;
- price and
- rolling resistance.
In terms of a company's overall efficiency, it can be more beneficial to select slightly more expensive tyres with a lower (= better) label instead of cheaper tyres.
