Shock Absorber System (04.03)
Description
Movement of each road spring is independently damped by
a telescopic, hydraulically-controlled shock absorber. Each
shock absorber is installed coax ially within the road spring.
Front spring and damper assemblies are located between
the upper suspension arm and attach to the lower
suspension arm and the body structure.
Rear spring and damper assemblies attach to the lower
suspension arm and the rear subframe, via a mounting
bracket, laying to the rear of the upper suspension arm.

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:

Road Test
A tyre vibration diagnostic proc edure always begins with a road test. The road test and customer interview (if available)
will provide much of the information neede d to find the source of a vibration.
During the road test, drive the vehicle on a road that is smoot h and free of undulations. If vibration is apparent, note and
record the following:
• The speed at which the vibration occurs
• What type of vibration occurs in each speed range
• How the vibration is affected by changes in the following types of vibration-sensitivity:
Torque Sensitive - This means that the condition may be improved or made worse by accelerating, decelerating, coasting,
maintaining a steady vehicle speed or applying engine torque.
Vehicle Speed Sensitive - This means that the vibration always occurs at the same vehicle speed and is not affected by
engine torque, engine speed or the transmission gear selected.
Engine Speed Sensitive - This means that the vibration occurs at varyin g vehicle speeds when a different transmission
gear is selected. It may sometimes be isolated by increasing or decreasing engine speed with the transmission in NEUTRAL
or by stall testing with the transmission in gear. If the condition is engine speed sensitive, the cause is probably not relate d
to the tyres.
If the road test indicates that there is tyre whine, but no sh ake or vibration, the noise originates with the contact between
the tyre and the road surface.
A thumping noise usually means that the tyre has a flat or soft spot making a noise as they slap the roadway. Tyre whine
may be distinguished from axle noise. Tyre whine remains the same over a range of speeds.
Symptoms
SymptomPossible Source(s):Action(s)
Tyres show excess wear on
edge of treads Tyres under-inflated Correct pressure to specification.
Vehicle overloaded Correct as required.
Tyres show excess wear on
edge of treads (having the
correct tyre pressures) Incorrect toe setting Set to specification.
Tyres show excess wear in
center of tread Tyres over-inflated Correct pressure to specification.
Other excessive tyre wear
problems Incorrect tyre pressure Correct pressure to specification.
Incorrect tyre and wheel usage Install correct tyre and wheel combination.
Geometry out of alignm
ent Check and adjust.
Loose, worn or damaged suspension
components Inspect, repair or install new suspension
components as necessary.
Wheel and tyre assembly out of
balance Balance wheel and tyre assembly.
Excessive lateral or radial runout of
wheel or tyre Check, repair or install a new wheel or tyre as
necessary.
Wheel mounting is difficult Incorrect application or mismatched
parts, including wheel studs and wheel
nuts. Corroded, worn or damaged parts Clean or install new parts.
Wobble or shimmy affecting
wheel runout Damaged wheel (eventually damaging
wheel bearings and causing uneven
tyre wear) Inspect wheel rims for damage and runout.
Install a new wheel rim as necessary.
Excessive vibration, rough
steering or severe tyre wear Loose or incorrect attaching parts Tighten or install new parts.
