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 made by different
manufacturers can have widely varying characteristics.
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,
and adjust accordingly.
Tire pressures increase slightly when the tires are hot. For an
accurate reading, tire 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 Information
Damage
Because of the high performance potential of this vehicle,
Aston Martin strongly recommend replacement of any damaged
or worn tire.
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.
