MAINTENANCE
Always drive with consideration for the condition of the
tyres, and regularly inspect the tread and side walls for any
sign of distortion (bulges), cuts or wear.
Note: If possible, protect tyres from contamination by
oil, grease and fuel.
Tyre Pressure
Before a long distance journey, the tyre
pressure must be checked.
Check the pressure (including the spare wheel) at least
once a month, when the tyres are cold.
If it is necessary to check the tyre pressure when they are
warm, you should expect the pressure to have increased by
0.3 to 0.4 bar (4.35 to 5.8 psi). In this circumstance, NEVER
let air out of the tyres in order to match the recommended
pressure (cold).
Valves
Keep the valve caps screwed down firmly - they prevent dirt
from entering the valve. Check the valve for leaks (listen
for a tell-tale hissing) when you check the tyre pressure.
Punctured Tyres
If a sharp object penetrates the tyre and remains in it, the
tyre may not leak. If you are aware of this occurring, reduce
speed immediately and drive with caution until the spare
wheel can be fitted, or repairs undertaken.
Note: If the sidewall of the tyre is damaged or
distorted, replace the tyre immediately, do not
attempt a repair.
Tyre Wear Indicators
At the bottom of the original tyre, there is a 1.6 millimeter
high wear mark perpendicular to the wheel rolling
direction. These indicators moulded into the tread pattern
at several points around the circumference. A mark on
the side of a tyre, such as the upper case letter TWI or
the triangle, indicating the position of the wear mark.
When the tread has worn down to 1.6 millimeter, the
indicators will come to the surface of the tread pattern,
producing the effect of a continuous band of rubber across
the width of the tyre.
