Maintenance
Factory installed tyres and road wheels are designed to
operate satisfactory when inflated to the recommended
inflation pressures (Refer to ’Inspection and Verification’,
page 4-4-4). The recommended pressures apply to vehicle
loads up to and including the full-rated load capacity.
Correct tyre pressures and driving technique have an
important influence on tyre life. Heavy cornering,
excessively rapid acceleration and unnecessary sharp
braking increase tyre wear.
Replacement tyres should follow the recommended:
The use of any other size or type may seriously affect:
Wheels need to be renewed when:
Safety
Tyre Replacement and Wheel
Interchanging
When replacement of tyres is required it is preferable to
install a complete vehicle set. S hould either the front or rear
tyres only show excessive wear, new tyres must be installed
to replace worn ones. Under no circumstances interchange
tyres from side to side, front to re ar or vice versa as individual
tyre wear produces unique characteristics depending upon
their position. If the position is changed after wear has
occurred, the performance of the tyre will be adversely
affected.
New tyres must be balanced before installing to the vehicle.

• Brake cooling
• Impact damaged
• Heavily corroded
• Porous • Wheel stud holes or seats
become damaged
• They have excessive radial or lateral runout.
ENSURE THAT TYRES ARE MOUNTED WITH THE
SIDEWALL MARKING ‘OUTSIDE’ SHOWING ON THE
OUTER SIDEWALL FACE.
CORRECT TYRE ROTATIONAL DIRECTION IS CRITICAL.
WA R N I N G
A TYRE AND WHEEL MUST ALWAYS BE CORRECTLY MATCHED. WIDER OR NARROWER TYRES THAN
RECOMMENDED COULD CAUSE DANGER THROUGH
SUDDEN DEFLATION.
WA R N I N G
WHEN CHANGING A WHEEL, MAKE SURE THAT THE VEHICLE CANNOT MOVE. ALWAYS APPLY THE
PARKING BRAKE AND SELE CT THE TRANSMISSION
PARK POSITION (AUTOMATIC TRANSMISSION ONLY).
WA R N I N G
NEVER RUN THE ENGINE WITH ONE WHEEL OFF THE GROUND, FOR EXAMPLE, WHEN CHANGING THE
WHEEL. THE WHEEL RESTING ON THE GROUND MAY CAUSE THE VEHICLE TO MOVE.
WA R N I N G
ALWAYS TIGHTEN THE WHEEL NUTS TO
SPECIFICATION. TOO TIGHT MAY CAUSE DAMAGE,
TOO LOOSE MAY ALLOW TH E WHEEL TO BECOME
DETACHED.
WAR NI NG
DO NOT MIX DIFFERENT TY PES OF TYRES ON THE
SAME VEHICLE. HANDLING MAY BE SERIOUSLY AFFECTED RESULTING IN LOSS OF CONTROL.
WAR NI NG
USE ONLY WHEELS AND WHEEL NUTS SUPPLIED BY
ASTON MARTIN. AFTER MARKET WHEELS OR WHEEL
NUTS MAY NOT INSTALL OR FUNCTION CORRECTLY
AND COULD CAUSE INJURY OR DAMAGE.
Caution
When a new tyre is installe d, always renew the tyre
valve.

Tyre Rotation
1. Press ‘Set’ for 2 seconds to enter level 1 programming .
2. Press ‘Mode’ repeatedly until ‘Tyre Rotation’ icon is displayed.
3. Press ‘Tyre’ to scroll to a tyre position. Press ‘Mode’ to display the current sensor identity.
4. Ensure that the road wheels and tyres are installed in the correct locations (see the colour code list above). Note
the correct code number for each road wheel.
5. Use ‘Tyre’ or ‘Mode’ to co rrect the sensor identity code
if required.
6. Repeat for the remaining tyres.
7. Press ‘Set’ twice to exit the programme.
Low Pressure Warning
1. Press ‘Set’ for 2 seconds to enter level 1 programming .
2. Press ‘Mode’ repeatedly until ‘Flat Tyre’ icon is displayed.
3. Press ‘Tyre’ to scroll to th e desired axle. Press ‘Mode’ to
display the current low pressure warning value. 4. Press ‘Tyre’ to increase or
‘Mode’ to decrease current
value.
5. Press ‘Set’ to enter the new value into memory.
Pressure Deviation Alert
This function sets the threshold for warning of a deviation
from normal tyre pressures.
1. Press ‘Set’ for 2 seconds to enter level 1 programming .
2. Press ‘Mode’ repeatedly until the ‘+-’ icon is displayed.
3. Press ‘Tyre’ to display the current value.
4. Press ‘Tyre’ to increase or ‘Mode’ to decrease the
current value
5. Press ‘Set’ to save the amended value.
6. Press ‘Set’ again to revert to normal operation.
High Temperature Alert
1. Press ‘Set’ for 2 seconds to enter level 1 programming .
2. Press ‘Mode’ until ‘ale rt’ icon is displayed.
3. Press ‘Tyre’ to display the current value of the high temperature alert.
4. Press ‘Tyre’ to increase or ‘Mode’ to decrease current
value
5. Press ‘Set’ to save the amended value.
6. Press ‘Set’ again to return to normal mode.
Units Selection
Use this function to select the combination of units for
pressure and temperature.
WAR NI N G
THE ROAD WHEELS AND TYRES ARE ASYMMETRICAL AND DIFFERENT SIZES FRONT AND REAR. THEY
MUST NOT BE ROTATED FRONT TO REAR. THIS FUNCTION SHOULD BE USED ONLY TO VERIFY
CORRECT TYRE POSITION. DO NOT CHANGE THE PROGRAMMED DATA.
Each sensor is identified by th e colour of a washer on the
tyre valve. Tyres are always in stalled in fixed positions and
must remain as follows:
• Right Front - Green (Code 1)
• Left Front - Red (Code 2)
