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.

SymptomPossible Source(s):Action(s)
SymptomDescription
Age Deterioration Cracking and crazing of the tread and side wall rubber, sometimes accompanied by carcass
deformation. An indication that the tyres have been in service for a very long time.
Neglected Cut Damage through accidental cuts or penetrations will extend in use due to continued flexing and /
or ingress of moisture and road matter.
Impact Fracture Resultant damage from impact fractures is not always visible externally and, therefore, as a safety
precaution the tyre should be removed and examined.
Casing fracture caused by severe localized impact through driving over kerbs, hitting potholes
and / or objects in the road.
A double fracture caused by crushing the side wall of the tyre between an object and the rim
flange.
In both instances, such damage can lead to sudd en and dangerous tyre deflation some time after
the impact occurred.

Repairs
In view of the high performance capability of the vehicle,
damaged tyres should be renewed and not repaired.
Care of Alloy Road Wheels
Aluminium alloy road wheels are covered with a protective
coating. To prevent corrosion it is essential that this coating
is not damaged. When removing or installing tyres only
equipment utilizing spigot or stud hole clamping must be
used. The equipment must not have any moving parts which
contact the road wheel, and ty re levers must not be used.
To clean road wheels use warm soapy water; stubborn stains
can be removed using a soft brush or by using a proprietary
alloy road wheel cleaner.
Road Wheel Alignment
It is important that correct road wheel alignment be
maintained. Misalignment causes tyre tread to be scrubbed
off laterally because the natural direction of the road wheel
differs from that of the vehicle.
A sharp ‘fin’ protrusion on the edge of each pattern rib is a
sure sign of misalignment.
• ‘Fins’ on the inside edges of the pattern ribs, particularly on the nearside tyre, indicate Toe-in.
• ‘Fins’ on the outside edges, particularly on the offside tyre, indicate Toe-out.
With minor misalignment, the ev idence is less noticeable
and sharp pattern edges may be caused by road camber
even when the road wheel alignment is correct. In such
c a s e s i t i s b e t t e r t o m a k e s u r e b y c h e c k i n g w i t h a n a l i g n m e n t
gauge. Road camber affects the direction of the vehicle by
imposing a side thrus t and , if le ft to follow its natural cou rs e,
the vehicle will drift towards its nearside. This is instinctively
corrected by steering towards the road centre and, as a
result, the vehicle runs crab wise. The diagram shows why
nearside tyres are very sensitive to too much Toe-in and
offside tyres to Toe-out. It also shows why sharp ‘fins’ appear on one tyre but not on
the other, and why the direction of misalignment can be
determined by noting the position of the ‘fins’. Severe
misalignment produces clea
r evidence on both tyres.
Front road wheels on a moving vehicle should be parallel.
Tyre wear can be affected noticeably by quite small
variations from this condition. It will be noted from the
diagram that even with parallel road wheels, the vehicle is
still out of line with its dire ction of movement, but there is
less tendency for the wear to be concentrated on one tyre.
The near front tyre sometimes persists in wearing faster and
more unevenly than the other tyres, even when the
mechanical condition of the vehicle and tyre maintenance
are satisfactory. The more severe the average road camber,
the more marked this tendency will be.
Caution
When a new tyre is installe d, always renew the tyre
valve.
