Winter Tyres; Tyre Sealant Kit - Aston Martin DB 9 2013 Manual

Extra Load: A class of P-metric or Metric tires designed to carry a
heavier maximum load at 41 psi/2.8 bar (43 psi/2.9 bar for Metric
tires]. Increasing the inflation pressure beyond this pressure will not
increase the tire's load carrying capability.
kPa: Kilo pascal, a metric unit of air pressure.
PSI: Pounds per square inch, a standard unit of air pressure.
Cold Inflation Pressure: The tire pressure when the vehicle has
been stationary and out of direct sun light for an hour or more and
prior to the vehicle being driven for 1 mile (1.6km).
Recommended Inflation Pressure: : The cold inflation pressure
found on the Safety Compliance Certification Label or Tire Label
(found on the edge of the driver's door).
Bead Area of the Tire: Area of the tire next to the rim.
Sidewall of the Tire: : Area between the bead area and the tread.
Tread Area of the Tire: Area of the perimeter of the tire that contacts
the road when mounted on the vehicle.
Rim: The metal support (wheel) for a tire or a tire and tube assembly
upon which the tire beads are seated.

Winter Tyres

The tyres installed as original equipment are designed with a rubber
compound, tread pattern and width specially suited for high speeds
in normal road conditions, but they are less suitable during extremes
of low temperatures, snow and ice. The use of winter tyres will
considerably improve handling during these conditions.
Only use Aston Martin approved winter tyres.
Warning: Maximum speed with winter tyres is 270 km/h.
Winter tyres must be used in vehicle sets, that is, installed on all four
wheels. Do not exceed the tyre speed rating when using winter tyres.
Contact your Aston Martin Dealer.
Snow Chains
Warning: The maximum speed when using snow chains is
48 km/h. Remove the snow chains immediately the roads are
clear of snow
These are available from your Aston Martin Dealer for temporary use
when driving in heavy snow conditions. Snow chains should only be
installed to the rear (driven) wheels.
Make sure that the installation instructions supplied with the
snow chains are kept in a safe place.

Tyre Sealant Kit

Warning: Do not use the system to seal a tyre that was
damaged while driving with insufficient air pressure (e.g. tyre
cuts, cracks, bumps or similar damage). Do not use the system to
seal tyres with side wall damage. Only punctures in the tread
area of tyres may be sealed.
Warning: Do not stand directly beside the tyre while the
compressor is pumping. Watch the side wall of the tyre. If there
are any cracks, bumps or similar damage set the compressor to
OFF. The journey should not be continued. Contact your nearest
Aston Martin Dealer.
Warning: If a tyre pressure of 1.8 bar cannot be reached then
the tyre can not be sealed. Do not attempt to re-inflate the tyre.
Contact your Aston Martin Dealer.
Warning: If the pressure in the tyre after driving for 3 km is
below 1.3 bar the tyre has not been effectively sealed. The
journey should not be continued. Contact your nearest
Aston Martin Dealer.
Warning: After a longer period of rest, the tyre pressure
should be rechecked.
