Waar komt bovenstaande tekst vandaan, uit het EU proposal document?
Hier de Franse vertaling in Engels. Google translate naar Nederlands is ruk.
Ga morgen dat document van de overheid eens wat meer doorspitten nog.
Behind this title which may seem alarmist, it should indeed be known that from 1 November 2018, the sale of tires TC4 class F and G in rolling resistance will be prohibited throughout Europe. In other words, the majority of road-approved slick tires (or semi-slicks) may disappear from dealer shelves in their current form. Explanations ...
The first interest of semi-slick tires today is to allow drivers to join a circuit by the road without changing equipment to turn once on site. For the same reason, these tires are sometimes homologated in series by some manufacturers on their most extreme sports. Their design favors a high level of grip on dry ground, they are primarily intended for use in competition, regional rallies type, or leisure driving during circuit trips and other track days organized by clubs. Unfortunately, this high adhesion potential which defines the RRC value (or rolling resistance coefficient) also has a disadvantage: it greatly increases the consumption and therefore the CO2 emissions ...
Introduced in 2011 by the European Union to promote the sale of greener, quieter and safer tires on wet ground, the regulatory labeling or Regulation (EC) n ° 661/2009 sets the legal characteristics of tires for the three categories of vehicles concerned: C1 (tourism / cars), C2 (light trucks) and C3 (heavy trucks). The rolling resistance, is the parameter, noted from A to G with a color code, indicating the energy performance. It is expressed in kilograms per tonne (kg / t) and influences vehicle consumption. Since its implementation, the European regulations had provided for the ban on 1 November 2018 for the sale and commissioning of new tires that did not meet the defined rolling resistance limit values (ie 10.5 kg / t for class C1 ).
So we are there today and the first victims of the application of the regulation will indeed be all the tires classified F and G. It is therefore directly, the majority of semi-slicks tires currently on the market are concerned until manufacturers review their ranges. For example, if the Michelin Pilot Sport Cup2 (rated E on most mounts) already escapes the award, we will have to say goodbye to Toyo Proxes R888 and R1R, Federal 595 RS-R, Nankang NS-2R, Yokohama Advan Neova AD08R and other Kumho ECSTA V70A if they do not adapt to the legislation.
To be complete on the subject, know that it however provides a period of up to 30 months from the date of prohibition to sell tires that were manufactured before the deadline and do not meet the requirements. Clearly, the sale of tires already manufactured can be done until April 2021, but it is almost certain that manufacturers will change their rubber compounds well before this deadline.
If you still fear to see disappear your favorite semi-slicks, there is still time to make a small stock in advance for your tracker ...
