Meaning
①
Product name
Individual tyre lettering from manufacturer.
②
DOT

Department of Transportation, responsible for tyre safety
standards.
③

④
TREADWEAR 280
Relative life expectancy for the tyre, with reference to a
US-specific standard test. Tyres with the specification
280
are 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 response of the tyre (
AA
,
A
,
B
or
C
). This is
tested under controlled conditions on certified testing
routes. 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 acceleration and
lateral stability or aquaplaning and traction under
maximum 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
temperature evaluation is based on tyres with correct
pressure and does not allow for excess pressure.
Excessive speed, incorrect pressure or excess pressure
can cause heat build-up or tyre damage. This applies to
one or a combination of these factors.
