Tyre lettering (example), meaning
5
TRACTION AA
Wet braking performance of the tyre (AA, A, B or C). The wet
braking performanc
e is tested under controlled conditions
on certified test tracks. Tyres marked C have a low traction
performance. The traction value assigned to the tyres is
based on linear traction tests and does not include accelera-
tion, lateral stability, or aquaplaning and traction under max-
imum load.
6
TEMPERATURE A
Temperature stability of the tyre at higher test speeds (A,
B or C). A and B tyres exc
eed legal requirements. The tem-
perature evaluation is based on tyres with correct tyre pres-
sure and does not allow for excess pressure. Excessive
speed, incorrect tyre pressure or excess pressure can cause
heat build-up or tyre damage. This applies to one or a com-
bination of these factors.
