‘Not available’ states Dutch market availability

Clarification to the tyres listed above:

• The tyre list ‘De Nieuwe Band’ (The New Tyre) has been developed by the Dutch government and contains information obtained from measurements that are executed in the Netherlands by the RDW (the road admission institute).

• The list of tyres has been developed to provide the Dutch consumer a clear insight into the three important qualifications of a tyre (safety, fuel efficiency and noise emission). This list is not comprehensive but offers the consumer the information on three important qualities for tyres at purchase.

• The list is not comprehensive and only shows a selection of currently available new tyres on the market. Tyres which are not listed have not been tested. This does not mean that non-listed tyres are inadequate on their qualities of safety, fuel efficiency and noise emission.

The procedure for testing (see below) noise emission is based on legal regulations. Regarding safety and fuel efficiency no legal regulations have been issued yet. In these cases the test procedure is anticipating on the to be expected future regulations

• The tyres of a certain brand and type are tested and classified based on the width of the tyre (clusters of tyres - see below). This has been done to prevent that every tyre has to be measured. The values of measurement are used to classify the tyre in several sizes at the same time.

(4)

• The list of tyres gets updated regular. If the tyre is in focus of the program, interested parties can sign up and the tyre will be included in the next measurement series. It is not possible to cover all the available new tyres on the market. Therefore the list will always display only a selection. This selection has been made because too many tyres are available on the market. The selection of individual brands is made based on the amount of factors (see below).

• Interested parties can have their tyres tested by the RDW after consultation with SenterNovem. Then the proper test procedure, approved by the government, has to be used and a test report is produced by the RDW. This report includes a description of the test procedure and results. Then the test results will be admitted to the list of tyres.

• The Dutch government developed ‘Duurzaam inkopen1’-criteria which are partly based on the list of tyres.

Test procedure

The (oncoming) European Tyre Directive defines the test procedures. For rolling sound emission the procedure is written down in the annex V of the current European Tyre

Directive, 92/23/EEG, that was amended in Directive 2005/11/EG. The procedures for testing the wet grip index and the rolling resistance coefficient will be defined in the coming

European Tyre Directive and based on the defined test procedures for wet grip in UN ECE-R117, Annex 5 and for rolling resistant coefficient in ISO 18164: 2005.

Standards

The current European Tyre Directive depicts the standards for rolling sound emission. These standards are not very strict. Almost all the tyres meet these standards easily. In the coming European Tyre Directive the standards for rolling sound emission will be raised. In this Directive also standards for wet grip (grip of the tyre on a wet surface) and rolling resistance will be introduced, partly to prevent negative trade offs regarding other important

qualifications of a tyre. The Directive has not been decreed yet. The standards however will most probably meet the following figures for passenger cars:

Silent: rolling sound emission

The coming rolling sound emission standards for tyres per width range are listed in the table below.

Width of the tyre: 185 195, 205, 215 225, 235, 245

Limit rolling sound emission: 70 dB(A) 71 dB(A) 71 dB(A) Safe: wet grip

The so called ‘wet grip index’ is the way in which the standard for wet grip is represented. This index indicates how the tyre performs in comparison with an accurately defined

reference tyre (called SRTT, Standard Reference Test Tyre). The wet grip index has to be at least at a level of 110%.

Fuel efficient: rolling resistance

The rolling resistance coefficient is the way the standard for rolling resistance is represented. The coefficient indicates what the connection is between the weight the tyre has to carry and

‘Duurzaam Inkopen’ is the Sustainable Procurement programme of the Dutch government. The Dutch

government, together with regional and local authorities, wants to stimulate the market for sustainable products. The Sustainable Public Procurement Programme is designed to encourage government authorities to take heed of environmental and social aspects when procuring products and services.

the power that is needed to keep the tyre rolling with this weight. The rolling resistance coefficient must not exceed 0.12 promil (‰), also expressed in kg/t.

Clusters of tyres

The (oncoming) European Tyre Directive sets out the standards and procedures for testing tyres. Every (brand and type of) tyre is available in a wide range of widths. Variations in width might lead to minor variations in performance. It is not possible to cover all the

available new tyres on the market. Therefore the list will always display only a selection. This selection has been made because too many tyres are available on the market. The basic

principle was that the test results have to make sure that a good comparison can be made between different kinds of tyres.

Wet grip and rolling resistance are more or less influenced by all the tyre aspects. In general it cannot be said that one aspect is the most prominent. That is the reason why we have chosen that, for rolling resistance and wet grip, only one test is carried out in a preference width. For one type of tyre the rolling resistance and the wet grip were tested in the same preference size. Also rolling sound emission is more or less influenced by all the tyre aspects, but there is one tyre aspect that is more prominent than the rest, that is to say the width. This is why a

different test procedure is chosen for rolling sound emission. For every width three clusters were assigned and per cluster the preference sizes were determined. For the middle category the same preference sizes are used as for rolling resistance and wet grip.

The list of tyres

The list of tyres gives an overview of all brands and types of tyres that have been tested. Per brand and type there is only one value for wet grip index and one for the rolling resistance coefficient and three values for rolling sound emission. The value for rolling sound emission is dependent on the width of the tyre and is categorised in three clusters:

• Tyres with a width up to 185 mm

• Tyres with a width of 195, 205 or 215 mm • Tyres with a width of 225, 235 or 245 mm.

Some tyres on the market exceed a 245 mm width. These kind of tyres are not taken into account due to their small market share. A blanc in the list means that tyres of this particular width are not (yet) available.

Factors on which the selection of the brand - type of a tyre is based

In the selection of the brands - types the following factors are taken into account. 1. The focus is on the commonly purchased new tyres, covering the biggest share of the

market and is therefore commonly available. If the manufacturer’s supply programme states that the tyres are mainly available in the “sportive” sizes, tyres exceeding a 245 mm width or extremely flat tyres with a low height-width relation of less than 45 mm are left out of the test procedures.

2. The aim is to cover the complete supply programme of A brands (popular brands) of the tyre manufacturers and importers. Newly introduced A-brands will be tested in the very next round of testing (in focus of the programme).

3. The aim is to also cover a significant share of the most popular B brands. The selection of these tyres is more subjective and is fed by requests from tyre manufacturers and importers, sales figures, test reports by third parties, to be expected good performances, etc.
