7. Trailer Running Gear Maintenance
These procedures must be carried out by competent persons. If you have any doubts about your
ability to complete any of the procedures we recommend these tasks are performed by your local
distributor.
7.1 Tyres
Tyres must be maintained at a pressure of 95p.s.i. (6.5bar).The pressure is also indicated on the
inspection door sticker. Under-inflation will adversely affect handling and fuel consumption and will
lead to premature wear. If seriously under-inflated, a tyre will overheat and fail very rapidly.
When renewing tyres, always ensure that you purchase a tyre of the same size and load/speed index
rating. This will be found on the sidewall of the tyre. E.g. 195/60R12C 104/102N(FRT). Different
makes or models of tyres of the same size can have widely differing load/speed index ratings and
inflation pressures. Use of a tyre with a lower rating can be dangerous. If in doubt, ask a tyre
distributor or our Customer Care department.
DO NOT REPLACE WITH LOWER RATED TYRES
The maximum gross weight figure given on the trailer plate is always equal to or less than the
approved maximum load for the tyres multiplied by the number of tyres on the trailer. In some cases
this includes a bonus load which is allowed for trailer use up to 60 mph. Other maximum load figures
are marked on some tyres. These do not apply to the UK or Europe and should be disregarded.
7.1.1
Tyre Repairs
Punctures should be inspected and repaired by a specialist tyre distributor. Do not fit tubes to
tubeless tyres as this can lead to a “blow out” in the event of a further puncture. If the tyre is too
severely damaged for a repair to be carried out the tyre should be replaced.
