10.
The number of plies in both the tread area,
and the sidewall area, indicates how many
layers of rubber coated material make up
the structure of the tyre. Information is also
provided on the type of materials used.
11.
Wear rate indicator. A tyre rated at 400 for
example, will last twice as long as a tyre
rated at 200.
12.
The traction rating grades a tyres
performance when stopping on a wet road
surface. The higher the grade, the better the
braking performance. The grades, from
highest to lowest are; AA, A, B and C.
13.
The maximum load which can be carried by
the tyre.
14.
Heat resistance grading. The tyres
resistance to heat is grade A, B or C, with
A indicating the greatest resistance to heat.
This grading is provided for a correctly
inflated tyre, which is being used within its
speed and loading limits.
15.
The maximum inflation pressure for the
tyre. 229, AVOIDING FLAT SPOTS.

TYRE CARE
Do not drive the vehicle if a tyre is
damaged, excessively worn or
incorrectly inflated.
Avoid contaminating the tyres with
vehicle fluids as they may cause
damage to the tyre.
Avoid spinning the wheels. The forces
released can damage the structure of
the tyre and cause it to fail.
If wheel spin is unavoidable due to a
loss of traction (in deep snow, for
example), do not exceed 50 km/h (30
mph).
Do not exceed the maximum pressure
stated on the sidewall of the tyre.
Note: All of the vehicle's tyres (including the
spare) should be checked regularly for damage,
wear and distortion. If you are in any doubt
about the condition of a tyre, have it checked
immediately by a tyre repair centre or a Retailer/
Authorised Repairer.
TYRE PRESSURES
Pressure checks should only be carried
out when the tyres are cold, and the
vehicle has been stationary for more
than 3 hours. A hot tyre at or below
recommended cold inflation pressure
is dangerously under-inflated.
Never drive your vehicle if the tyre
pressures are incorrect. Under-inflation
causes excessive flexing and uneven
tyre wear. This can lead to sudden tyre
failure. Over-inflation causes harsh
ride, uneven tyre wear and poor
handling.
