Maintenance
Tires
Tires of the correct type, manufacturer and dimensions, with correct
cold inflation pressures are an integral part of every vehicle’s design.
Regular maintenance of tires contributes not only to safety, but to the
designed function of the vehicle.
Road holding, steering and braking are especially vulnerable to
incorrectly pressurized, badly installed or worn tires.
Tires of the correct size and type, but of different make have widely
varying characteristics.
Only install tires approved by Aston Martin.
Tire Pressures
Make sure that correct tire pressures are carefully maintained. Road
holding, steering, braking and tire wear are especially vulnerable to
incorrect tire pressures.
Check tire pressures regularly and before starting any journey. Re-
inflate any tire with a low pressure at the earliest opportunity.
Pressures increase slightly when the tires are hot. For an accurate
reading, pressures should be checked when the tires are cold. After
adjusting the tire pressures, make sure that the valve caps are securely
replaced to provide an additional air seal and to prevent the ingress
of dirt.
Tire Service
Because of the high performance potential of this vehicle,
Aston Martin strongly recommend replacement of any damaged or
worn tire.
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.
They are also of different sizes on the front and rear axles, therefore
complete wheels cannot be swapped between axles. Complete
wheels can, however, be swapped from side to side on the same axle.
Damage
Tires should be examined at regular intervals for wear and damage.
Inspect the tire treads and sidewalls for damage, i.e. bulges in the
tread or the sidewalls, cracks in the tread groove and separation in
the tread or the sidewalls. If damage is observed or suspected have
the tire inspected by a tire professional.
Stones or other objects which have become lodged in the tire treads
should be carefully removed.
Flat Spots
It is a characteristic of high performance tires that temporary ’flat
spots’ may develop if the vehicle is left standing in high or low
ambient temperatures for any length of time.
These ’flat spots’ will manifest themselves as minor vibrations when
the vehicle is first driven from cold. As the tires warm up to operating
temperature, normal tire shape should be restored and the vibrations
cease. If vibrations persist, consult your Aston Martin Dealer.
Age
Local regulations on tire life may apply.
Tires degrade over time, even when they are not being used. It is
recommended that tires generally be replaced after five years of
normal service. Heat caused by hot climates or frequent high loading
conditions can accelerate the aging process.
