TYRES AND SERVICE

Obtaining satisfactory life and service from the tyres is largely a matter within the user's

control because the first essential is correct inflation. Check tyre pressures with a low

pressure gauge at least once a week. Inflate as may be necessary.

Avoid unnecessary, or " stunt," acceleration and fierce braking, which wear out tyres

by causing wheel spin and skid.

Do not drive in tram lines. It is dangerous, especially when wet, and the uprising edges

of worn rails will damage the tyres.

Remove flints, etc., that become embedded in the tread and, if any oil gets on the tyres

or spokes, clean it off with petrol.

Make sure the front and rear wheels are in track. When the wheel alignment is correct,

a piece of thin string stretched taut across both wheels, about four inches from, and

parallel to, the ground, should just touch each tyre at both sides of the wheel centres.

Alternatively, a straight wooden batten, about five feet long, is handy to use for checking

wheel alignment. This should be applied, as in the case of string, parallel to and about

four inches from the ground.

Always check the rear chain adjustment, and the rear brake adjustment, after making an

alteration to the rear wheel position.
