TREADWEAR 280
Relative life expectancy for the tyre, with reference to a U
S-
specific standard test. A tyre with the specification 280 is
used up at a rate of 2.8 times more slowly than standard

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.
