WARNING
Using Different Tyre Types:
Driving your vehicle with different
types of tyres is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tyre, use only the same
type tyres (radial, bias-belted, bias-type)
on all four wheels.
Using Wrong-Sized Tyres:
Using any other tyre size than what is
speci¿ ed for the vehicle (page 9-8 )
is dangerous. It could seriously affect
ride, handling, ground clearance,
tyre clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tyres that
are the correct size speci¿ ed for the
vehicle.
