Tyres - Aston Martin DB 9 2013 Manual

Clutch Bedding-in
The vehicle needs to be driven carefully for the first 1000 miles/1600
km before the clutch is fully bedded in. If the vehicle is not driven
carefully during this time, early failure of the clutch can occur. This is
not covered by warranty as it is incorrect use of the clutch and is
considered 'wear'.
For more information on the correct procedure of bedding-in a new
clutch, contact your Aston Martin Dealer.
Failure to bed-in a new clutch will result in reduced
performance, and possible clutch damage.

Tyres

Tyres of the correct type, manufacturer and dimensions, with correct
cold inflation pressures are an integral part of every vehicle's design.
Regular maintenance of tyres 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 tyres.
Tyres of the correct size and type, but of different make have widely
varying characteristics.
Only install tyres approved by Aston Martin.
Tyre Pressures
Make sure that correct tyre pressures are carefully maintained. Road
holding, steering, braking and tyre wear are especially vulnerable to
incorrect tyre pressures.
Check tyre pressures regularly and before starting any journey. Re-
inflate any tyre with a low pressure at the earliest opportunity.
Pressures increase slightly when the tyres are hot. For an accurate
reading, pressures should be checked when the tyres are cold. After
adjusting the tyre pressures, make sure that the valve caps are
securely replaced to provide an additional air seal and to prevent the
ingress of dirt.
Tyre Service
Because of the high performance potential of this vehicle,
Aston Martin strongly recommend replacement of any damaged or
worn tyre.
The recommended tyres for this vehicle are asymmetrical and must
be installed to the wheel with the tyre 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
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.
