fig. 190Tire labeling (example), meaning
Relative service life expectancy for the tire, based on a US-
specific standard test. A tire with the specification 280 will
wear 2.8 times more slowly than a standard tire with a tread
wear value of 100. The tire performance depends on the
usage conditions and may differ significantly from the
standard values depending on the driving behavior,
maintenance, different road conditions, and climate
conditions.
TREADWEAR 280
Wet braking capability of the tire ( AA, A, B or C). The wet
braking capability is measured under controlled conditions
on certified test courses. Tires marked with C have low
traction performance. The traction value assigned to tires is
based on straight-line traction test and includes neither
acceleration and cornering, nor hydroplaning and traction
under maximum load.
TRACTION AA
Temperature stability of the tire at high speeds on the test
stand (A, B or C). Tires marked with A and B exceed the
legal requirements. The temperature rating is based on the
tires being inflated to the correct pressure and not
overinflated. Excess speed, incorrect tire pressure, and
overinflation either alone or in combination can cause heat
to build up and cause tire damage.
