The worst case of test tires for tyre noise:

TEST SIZE : 225/40ZR18 92W XL

Because of : Largest section width (if the same section width: lowest aspect ratio; largest rim size)

The testing tire designation for wet grip：

TEST SIZE : 205/55R16 91V

Because of : Any tyre size that meets ten percent (10%) or more above the minimum required wet grip value

can represent the whole tyre size range of the tread pattern type.

For any tyre size the limited value for the test tire is: 1.1

The testing tire designation for rolling resistance:


Because of : The RRC value of tested candidate tyre other than the worst case tyre shall be equal or less than

new calculated limit vaule.

The lowest load index is 75, the calculate limit value for the tested tyre is: 10.24 N/kN

The testing tire designation for snow performance：


Because of : Any tyre size that meets the required value of the regulation plus (at least ) the extra safety margin

may represent the whole tyre type range.

The limited value for the test tire is: 1.10

Remark: The tread pattern may be named SC501 for WANLI/ NEGOTIATOR // NC501 for SUNNY // RC501 for APTANY

// DC501 for DIAMOND // FC501 for FORTUNA // AS2 for AUTOGREEN/ GOWIND/ MAZZINI // TOUR-X for KETER

REPORT Nº CN19030811SUMMARY

1. Dimensions included in the type of tyre : See Manufacturer’s technical documentation attached

2. Tyre sizes selected for testing

2.1. Tyre size tested for rolling sound emissions : 225/40ZR18 92W XL (largest section width) See Annex 1, Test report CN19010187, IDIADA, 25/12/2018

2.2. Tyre size tested for adhesion on wet surfaces: 205/55R16 91V (meets extra 10%) See Annex 2, Test report CV19010880, IDIADA, 01/02/2019

2.3. Tyre tested for rolling resistance : 205/55R16 91V (new calculated limit value)See Annex 3, Test report CN18110113, IDIADA, 02/11/2018

2.4. Tyre tested for snow performance : 205/55R16 91V (new calculated limit value)See Annex 4, Test report CV19010314, IDIADA, 15/01/2018

3. Reason(s) of extension (if applicable) : - Addition of brand name and trade description- Addition of new tyre sizes- Deletion of trade description

4. New calculated limit value according to Announcement for the technical service 2018-01

4.1 In case a test tyre is selected which does not have the worst case properties the following applies:A test tyre, not having the worst case properties, performing at least ten percent (≥10%) above the minimum required wet grip performance level can represent the whole tyre size range of tyre types.New limit value is 1.1 < 1.40 (Wet grip test result)

4.2 To verify if a lower load index (LIlowest) meets the requirements of the regulation, the limit value for the tested tyre ( LIcandidate ) is calculated by the formula:Calculated limit value = (RRC-limit value R117 – 0.3# N/kN) – 0.06* x (LIcandidate – LIlowest)# the limit value of the regulation will be increased by a safety margin of 0.3 N/kN* the slope of rolling resistance coefficient versus load index is fixed on 0.06.Calculated limit value = (11.5 – 0.3# N/kN) – 0.06* x (91 - 75) = 10.24 N/kN > 8.44 N/kN (test result)

4.3 If a test tyre is selected, not having the worst case properties, the minimum required Snow grip index plus an extra safety margin must at least be met Braking method C1: 1.07 + safety margin 0.03 = 1.10 < 1.16 (Snow grip index test result)

5. List of Annexes to this report5.1. Annex 1: Test report according to rolling sound emission level.5.2. Annex 2: Test report according to adhesion on wet surfaces.5.3.
