Tyre lettering (example), meaning

TREADWEAR 280
Relative life expectancy for the tyre, with reference to a
US-
specific
standard test. A tyre with the
specification
280 is
used up at a rate of 2.8 times more slowly than standard
tyres which have a treadwear value of 100. The performance
of tyres is determined by how they are used and can notably
deviate from norm values due to driving style, maintenance,
road surface and climatic conditions.
5
TRACTION AA
Wet braking performance of the tyre (AA, A, B or B). The wet
braking performance 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 exceed 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.
