TYRES

Practical advice - 141

Incorrect tyre pres
sures lead to abnormal
tyre wear and unusually
hot running. These are
factors which may seriously affect
safety and lead to :
– poor road holding.
– risk of bursting or tread separa-
tion.
The pressure depends on the
load and the speed of use. Adjust
the pressure according to the
conditions of use (refer to the la-
bel affixed to the edge of the
driver’s door).
The pressures should be checked
cold : ignore higher pressures which
may be reached in hot weather or fol-
lowing a high speed journey.
If the tyre pressures cannot be
checked when the tyres are cold, in
crease the pressures from 0.2 to 0.3
bar (or 3 PSI).
Never deflate a hot tyre.
Special note
Depending on the vehicle, there may
be an adapter which needs to be posi-
tioned on the valve before air is added.
Please be aware that a
poorly tightened or miss-
ing valve cap can make
the tyres less airtight and
lead to pressure loss.
Always use valve caps identical to
those fitted originally and tighten
them fully.
Changing wheels around
Swap the wheels as shown in above
picture with every regular intervals 12
months / 10000 Kms (which ever
comes earlier).
Swapping needs to be done along with
wheel balancing and wheel alignment.
Emergency spare wheel
Refer to the information on the “Emer-
gency spare wheel” and “Changing a
wheel” in Section 5.
Fitting new tyres
For safety reasons, this
operation must be car-
ried out by a specialist.
Fitting different tyres may change
your vehicle as follows :
– it may mean that your vehicle
no longer conforms to current reg-
ulations.
– it may change the way it han-
dles when cornering.
– it may cause the steering to be
heavy.
– It may affect the use of snow
chains.
