Meaning
manufacture:
JHCO Identifier of producing plant and
CHWS specifications of the tyre manufacturer
for size and characteristics.
2213 Manufacturing date: 22nd week in
2013.
Relative life expectancy for the tyre, with
reference to a US-specific standard test. Tyres
with the specification 280 wear 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
deviate significantly from standard values due to
driving style, maintenance, road surface and
climatic conditions.
Wet braking response of the tyre (AA, A, B or C).
The wet braking response 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
acceleration, lateral stability, aquaplaning or
traction under maximum load.
Temperature stability of the tyre at higher test
bench 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.
