For all normal purposes the minimum pressures for the three types should be :- |
||||||
|
Front |
MOV & MAC. | 16-lbs. | MSS | 16-lbs | ||
|
Rear |
18-lbs. | 16-lbs. | ||||
Additional loading such as a heavy rider, pillion passenger, or the addition of a sidecar will require a higher pressure. Owing to the difference in the various sidecars available we do not quote pressures, but recommend that the loaded weight upon each wheel be checked on a public weighbridge. With this information the correct pressures can be found from the table. Check the pressures weekly and inflate if loss of pressure is noticed.
NEVER RUN TYRES UNDER-INFLATED.
Occasionally examine the tyres for cuts, and in order to remove flints or nails which may be partly embedded in the treads. Partly deflate tyres to remove nails or flints.
