Regulation (EC) No 1222/2009 of the European Parliament and of the Council of 25 November 2009 on the labelling of tyres with respect to fuel efficiency and other essential parameters (Text with EEA relevance)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
Legislation.gov.uk publishes the UK version. EUR-Lex publishes the EU version. The EU Exit Web Archive holds a snapshot of EUR-Lex’s version from IP completion day (31 December 2020 11.00 p.m.).
Point in time view as at 31/01/2020.
There are outstanding changes not yet made to Regulation (EC) No 1222/2009 of the European Parliament and of the Council. Any changes that have already been made to the legislation appear in the content and are referenced with annotations.
Changes and effects yet to be applied by the editorial team are only applicable when viewing the latest version or prospective version of legislation. They are therefore not accessible when viewing legislation as at a specific point in time. To view the ‘Changes to Legislation’ information for this provision return to the latest version view using the options provided in the ‘What Version’ box above.
The measured Rolling Resistance Coefficient ( RRC m ) in a reference laboratory ( l ) shall be aligned to the assigned values of the network of reference laboratories.
The RRC m in a candidate laboratory ( c ) shall be aligned through one reference laboratory of the network of its choice.
A set of five or more alignment tyres shall be selected for the alignment procedure in compliance with the criteria below. One set shall be selected for C1 and C2 tyres together, and one set for C3 tyres.
The set of alignment tyres shall be selected so as to cover the range of different RRCs of C1 and C2 tyres together, or of C3 tyres. In any event, the difference between the highest RRC m of the tyre set, and the lowest RRC m of the tyre set shall be at least equal to:
3 kg/t for C1 and C2 tyres; and
2 kg/t for C3 tyres.
The RRC m in the candidate or reference laboratories ( c or l) based on declared RRC values of each alignment tyre of the set shall be spaced out as follows and distributed uniformly:
1,0 +/– 0,5 kg/t for C1 and C2 tyres; and
1,0 +/– 0,5 kg/t for C3 tyres.
The selected tyre section width of each alignment tyre shall be:
≤ 245 mm for machines measuring C1 and C2 tyres; and
≤ 385 mm for machines measuring C3 tyres.
The selected tyre outer diameter of each alignment tyre shall be:
between 510 to 800 mm for machines measuring C1 and C2 tyres; and
between 771 to 1 143 mm for machines measuring C3 tyres.
Load index values shall adequately cover the range of the tyres to be tested, ensuring that the rolling resistance force (RRF) values also cover the range of the tyres to be tested.
Each alignment tyre shall be checked prior to use and replaced when:
it shows a condition which makes it unusable for further tests; and/or
there are deviations of RRC m greater than 1,5 per cent relative to earlier measurements after correction for any machine drift.
The reference laboratory shall measure each alignment tyre four times and retain the three last results for further analysis, in accordance with paragraph 4 of Annex 6 of UNECE Regulation No 117 and its subsequent amendments and applying the conditions set out in paragraph 3 of Annex 6 of UNECE Regulation No 117 and its subsequent amendments.
The candidate laboratory shall measure each alignment tyre (n + 1) times with n being specified in section 5 and retain the n last results for further analysis, in accordance with paragraph 4 of Annex 6 of UNECE Regulation No 117 and its subsequent amendments and applying the conditions set out in paragraph 3 of Annex 6 of UNECE Regulation No 117 and its subsequent amendments.
Each time an alignment tyre is measured, the tyre/wheel assembly shall be removed from the machine and the entire test procedure specified in paragraph 4 of Annex 6 of UNECE Regulation No 117 and its subsequent amendments shall be followed again from the start.
The candidate or reference laboratory shall calculate:
the measured value of each alignment tyre for each measurement as specified in Annex 6, paragraphs 6.2 and 6.3, of UNECE Regulation No 117 and its subsequent amendments (i.e. corrected for a temperature of 25 °C and a drum diameter of 2 m);
the mean value of the three (in the case of reference laboratories) or n (in the case of candidate laboratories) last measured values of each alignment tyre; and
the standard deviation (σ m ) as follows:
where:
is the counter from 1 to p for the number of alignment tyres
is the counter from 2 to n for the number of repetitions of each measurement for a given alignment tyre
is the number of repetitions of tyre measurements (n ≥4)
is the number of alignment tyres (p ≥ 5)
The measured RRC values corrected from drum diameter and temperature shall be rounded to 2 decimal places.
Then the computations shall be made with all digits: there shall be no further rounding except on the final alignment equations.
All standard deviation values shall be displayed to 3 decimal places.
All RRC values will be displayed to 2 decimal places.
All alignment coefficients (A1 l , B1 l , A2 c and B2 c ) shall be rounded and displayed to 4 decimal places.]

This timeline shows the different versions taken from EUR-Lex before exit day and during the implementation period as well as any subsequent versions created after the implementation period as a result of changes made by UK legislation.
The dates for the EU versions are taken from the document dates on EUR-Lex and may not always coincide with when the changes came into force for the document.
For any versions created after the implementation period as a result of changes made by UK legislation the date will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force.
