Aston Martin One-77 2010 Owner's Manual page 141

Because of the high performance potential of this
vehicle, Aston Martin strongly recommend
replacement of any damaged or worn tyre.
Damage
Tyres should be examined at regular intervals for wear
and damage. Inspect the tyre 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
tyre inspected by a tyre professional.
Stones or other objects which have become lodged in
the tyre treads should be carefully removed.
Flat Spots
It is a characteristic of high performance tyres 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 tyres warm up to operating temperature, normal
tyre shape should be restored and the vibrations cease.
If vibrations persist, consult your Aston Martin Dealer.
Age
Tyres degrade over time, even when they are not being
used. It is recommended that tyres generally be
replaced after five years of normal service. Heat caused
by hot climates or frequent high loading conditions can
accelerate the aging process.
Local regulations on tyre life may apply.
New Tyres
New tyres should not be installed to the front wheels in
combination with worn rear tyres, as rear end stability
will be affected. When new tyres are required consult
your Aston Martin Dealer for advice if the rear tyres are
also worn. Each wheel and tyre unit must be balanced
dynamically and measured for Radial Force Variation
(RFV) to make sure of efficient steering, optimum tyre

wear and maximum ride comfort. Because of the
potentially high speeds, it is essential that wheel
balancing is carried out when new tyres are installed.
