Note on the use of winter tyres
Summer t yres provide optimum perfor
-
mance at ambient temperatures above
+7 °C. Below this point, the t yre com -
pound begins to harden and braking
distances are increased. We therefore recommend that you fit winter t yres
during the colder months of the year so
that you can drive your Boxster safe in
the knowledge that it will continue to
meet our high standards for driving safet y
even at low temperatures. All winter t yres approved by Porsche are identified by
an ‘N’ designation on the sidewall. These
t yres are beneficial because they have
been optimised to produce less noise,
rolling resistance is reduced for improved
fuel economy, and, importantly, braking
