Summer Tires
The recommended tires for this vehicle are asymmetrical and
must be installed to the wheel with the tire mark 'OUTSIDE' on
the outside of the wheel rim.
The tires are also of different sizes on the front and rear axles,
therefore complete wheels cannot be swapped between axles.

Maintenance and Technical Data
Winter Tires
The tires 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 tires will considerably improve handling during these
conditions.
Only use Aston Martin approved winter tyres - contact your Aston
Martin dealer for more information.
Warning: The maximum speed limit of the vehicle should
be reduced when winter tyres are installed. Winter tire
speed limits and information should be provided upon
installation. Please consult your Aston Martin Dealer for
more information.
Winter tyres must be installed to the correct winter wheels.
Winter tyres must be used in vehicle sets, that is, installed on all
four wheels. Do not exceed the tire speed rating when using
winter tyres.
Snow Traction Devices
Warning: The maximum speed when using snow traction
devices is 48 km/h. Remove the snow traction devices
immediately when the roads are clear of snow.
These are for temporary use when driving in heavy snow
conditions. Snow traction devices should only be installed to the
rear (driven) wheels. For more information regarding the correct
snow traction device to fit to your vehicle, contact your Aston
Martin Dealer.
