USA Tyre Gradings
The following information relates to the tyre grading system
developed by the National Highway Traffic Safety
Administration which grades tyres by tread wear, traction
and temperature performance.
Tr e a d W e a r
Tread wear grade is a comparat ive rating based on the wear
rate of the tyre when tested under controlled conditions
(specified government test course). For example, a tyre
graded 150 would wear one and a half times less on the
government course than a tyre graded 100. Relative
performance of the tyres depends upon actual conditions of
use and may depart significantly from normal due to
variations in driving habits, service practices and differences
in road characteristics and climate.
Tr a c t i o n
Traction grades, A (highest), B and C represent a tyre’s ability
to stop in wet conditions measured on specified government
test surfaces of asphalt and concrete.
Te m p e r a t u r e
Temperature grades, A (highest), B and C, represent a tyre’s
resistance to the generation of wear and its ability to
dissipate heat when tested under controlled conditions
(specified indoor laboratory test road wheel). Sustained high
temperature can cause the material of a tyre to degenerate
and reduce tyre life; excessive temperatures can lead to
sudden tyre failure. Grade ‘C’ corresponds to a level of
performance which all passenger vehicle tyres must meet
under Federal Motor Vehicle Safety Standard No. 109.
Grades ‘B’ and ‘A’ represent higher levels of performance
than the minimum required by law. Aston Martin grade as follows:

Step 1 for all Wheel Nuts 80 60
Step 2 for 22 mm Wheel Nuts 135 100
Step 2 for Titanium Wheel Nuts 150 111

TRACTION GRADE IS BASED ON BRAKING (STRAIGHT AHEAD) TRACTION TESTS AND DOES NOT INCLUDE
CORNERING (TURNING) TRACTION.
WAR NI NG
TEMPERATURE GRADE IS ESTABLISHED FOR A TYRE THAT IS PROPERLY INFLATED AND NOT
OVERLOADED. EXCESSIVE SPEED, UNDER INFLATION
OR EXCESSIVE LOADING, WHETHER SEPARATELY OR
IN COMBINATION, CAN CAUSE HEAT BUILD-UP AND POSSIBLE TYRE FAILURE.

Body Ventilation (12.01)
Air Intake & Distribution System
Outside air enters the plenum via inlets at the base of the
windscreen.
Fresh mode - Air is drawn in through the plenum and into
the blower unit. From the blower unit air enters the A/C unit
where it is cooled and dehumidified as it passes through the
evaporator. It is then ‘reheated’ to the selected temperature
as it passes through the heater matrix,. Air flows from the cabin into th
e boot via air vent grilles and
through apertures in the rear parcel shelf. The air is
exhausted from the vehicle through extraction vent
assemblies (incorporating one way flaps) in the lower part of
the rear bumpers, concealed by the bumper trim.
Recirculation mode - The air in the passenger
compartment is drawn into the A/C system via the re-
circulation air inlets on the blower unit.
The A/C unit is linked and sealed to the defrost / demisting and cabin air ducting assemblies. The A/C unit incorporates
two actuator operated flaps which regulate airflow to the selected air flow mode and temperature blend.
The centre vent duct incorporates a baffle plate which balances the volume of airflow of the centre and end of dash vents.

Major Components
Compressor
• Engine mounted, driven by the accessory drive belt
• Variable displacement type
• High-pressure relief valve, to avoid system over-pressure
• ECU controlled clutch energised via a relay
Receiver drier
• Vertically mounted on the right-hand side of the engine bay
• The high-side charge port is installed to the high side entry pipe to the receiver drier
Condenser
• Multi-pass fin-over-tube type, mounted in front of the engine cooling pack and directly to the radiator
Trinary switch
Located in the compressor discharge pipe
• Provides a signal, via the A/C module, to the PCM, to disengage the compressor clutch should the refrigerant
pressure be less than 2 bar or greater than 30 bar
• Provides a hard-wired signal to the PCM, to switch the cooling fans to HIGH speed at 22 bar rising pressure and
to LOW speed at 17,5 bar falling pressure
• Provides a hard-wired signal to the PCM, to switch the radiator cooling fans to LOW speed at 12 bar rising
pressure and to switch the fans OFF at 8 bar falling
pressure
Expansion Valve
The expansion valve is located on the outside of the A/C unit
and comprises of a diaphragm, connected by a capillary
tube to a temperature sensing bulb, which regulates the
valve according to temperature variations at the evaporator
outlet pipe. This component is not serviceable.
