Tire & Wheel
Maintenance of correct inflation pressure (46PSI) is the basic essential factor in obtaining the best
performance and life from a pneumatic tire. The air inside the tire enables it to carry a load. It is only
when the inflation pressure is correctly matched that the tire adopts its optimum cross‐sectional shape
and the tread rests correctly on the road surface with the correct pressure distribution across its whole
width, thus allowing the sidewalls to provide the required degree of flexibility. Both performance and life
of the tires will suffer if pressures are unsuitable so both over or under inflation ( or overload which has
the same effect ) are similary undesirable.
Underinflation
results in excessive deflection which increases the heat generated by the tire, this in turn
leads to its eventual disintigration. In addition the distortion of the casing will result in the lifting of the
centre of the tread, thus overloading the outer edges of the tread, producing rapid wear at those points.
Overinflation
distorts the tire’s casing, but in this case it tends to lift the outer edges of the tread off the
road surface and imposes extra load and more rapid wear on the centre of the tread. Owing to reduced
flexibilty the tire will be more vulnerable to impact damage, ride quality will be impaired and the wheels
will be more liable to bounce which can result in skidding due to brakes locking.
Unlike cars on which tire loads do not vary greatly it is not practicable to provide standard
recommendations. This is because tire loading and operating conditions vary widely.
Remember that spreaders travel laden one way and unladen in the opposite direction, it is therefore
desirable to estabish a suitable mean pressure that mimimises both under inflation when loaded and
excessive over inflation when running light.
IMPORTANT
CHECK WHEEL NUT TORQUE AFTER EACH LOAD FOR THE 1
ST
10 LOADS AND THEN DAILY FOR THE FIRST WEEK
AND ONCE A WEEK THEREAFTER.
