The recommended tyre pressures are based on a rider’s weight of 140
lbs. If the rider is heavier, increase the pressures as follows: —
Front tyre: Add one lb. Per sq. in. for every 28 lb. Increase above
140 lb.
Rear tyre: Add one lb. Per sq. in. for every 14 lb. Increase above
140 lb.
If additional load is carried in the form of a pillion passenger or
luggage, the actual load bearing upon each tyre should be determined
and the pressures increased in accordance with the Dunlop Load and
Pressure Schedule.
