incorrect pressure - under-inflated.
- Tyre with irregular wear in the centre of the
tread: incorrect pressure - over-inflated.
- Tyre wear with stepped wear profile: shock
absorber not working properly.
- Tyres on the same axle with irregular wear on
a single side wall: toe out of tolerance.
- Only one tyre on the same axle with an irregu-
larly worn side wall: camber out of tolerance.
Vehicles with just one register.
Adjust the total toe to the value specified by
the manufacturer.
Set the two front half-toes so that they are equal.

column and move it to the correct position; if the

Adjusting vehicle with power steering.
Before making the adjustments start the engine,
turn the steering wheel to the limit position in
both directions, set the steering-wheel correctly
and lock it in place.
During the adjustment operations it does not
matter whether the engine is left running or
stopped, except for cars where adjustment with
the engine on is specified.
Vehicles with hydro-pneumatic or intelligent
suspension systems.
Adjust the vehicle with the engine running and
the suspensions at the normal height for use.
Vehicles with fixed rear axle.
The rear axle should still be measured to identify
any excessive anomalies, after which adjust the
front-half-toes in relation to the thrust axis; this
eliminates the crooked steering-wheel problem.
