5.5.2 Tyre Repairs
Punctures should be inspected and repaired by a specialist tyre Distributor. Not all punctures can be
repaired and tyres with other damage may not be suitable for repair.
Do not fit tubes to tubeless tyres as trapped air between the tube and the tyre will eventually leak
away rsulting in low pressure and tyre failure.
5.5.3 Changing a Wheel
•
All the trailers covered by this manual are supplied with a spare wheel as standard. The exact
location varies but access does not involve tipping or tilting the trailer except in the case of
the CT177.
•
The CT177 spare wheel is located alongside the toolbox in the front of the load bed.
Depending on the length of the vehicle being transported, its weight distribution and
therefore its position on the trailer, it may be necessary to unload the transported vehicle to
access the spare.
•
Wheel changing inevitably means jacking some part of the trailer so that the damaged wheel
can be released. Before proceeding develop a clear plan of how to get the damaged wheel off
the ground.
•
In the particular case of Tiltbeds requiring a front or centre axle wheel change, by far the
easiest way to get the front wheels off the ground is to tilt the load bed. (See relevant Tiltbed
section for correct procedure
–
important.)
•
In all other cases, Tiltbed rear axles and Tippers, an appropriately rated jack will be needed.
Assume that the jack is lifting half the actual weight of trailer plus load. The best position for
the jack, even in the case of a front axle wheel change, is under the chassis immediately
behind the rear spring.
•
In the particular case of the CT177, the only jacking point is the underside of the cross-
member which projects through the side-plate just behind the wheels.
•
Jacking under the axle beam, close to the spring seat is acceptable if the jack is of a type which
“cradles” the axle
beam and cannot slip off. If the CT177 is jacked under the axle beam it will
be impossible to remove the wheel.
