The maintenance of correct tyre pressures is important to the life of the tyres
and behaviour of the steering and suspension.
Examine the tyres occasionally for flints or other road matter which may have
become embedded in the tread. By using fuel sparingly, clean off any oil which
may have got on the tyres. Driving into or over sharp edged kerbs is liable
to fracture the walls of the tyres and should be avoided where possible.
Changing Position of Tyres
Every 3,000 miles interchange the front tyres with rear tyres.
interchanging between left front and right rear and between right front and
left rear provides the most satisfactory first change. This reverses the direction
of rotation and keeps the wear of the tyres even and uniform.
Alignment of the front wheels is most important in its effect on tyre wear
and good steering. Excessive toe-in will lead to severe tyre wear, particularly
on the " kerb side " front tyre.
The front wheel alignment should be parallel to ⅛

When Goodyear D.F.S. and Michelin X tyres are fitted the front wheel align-
ment should be parallel to 1/16 " toe-in.
To Check and Adjust Wheel Alignment
If adjustment is found necessary it should be carried out equally on the
two outer tie-rods. When adjustment is complete ensure that the ball
joints are in the centre of " swing " before securely tightening the tie-
rod locking nuts.
A screw-jack is provided which is adapted to lift either side of the car as required.
Apply the handbrake, or chock the wheels which will remain on the ground,
before operating the jack.
