Regular checking of tyre pressures is essential for good mileage to be obtained from the tyres. Under inflation, particularly, is very destructive to the casings, and by increasing the rolling resistance tends to increase the fuel consumption.

It should be noted when refitting a cover, or fitting a new one that on some makes the walls are marked to indicate how the cover should fit in relation to the rim. A white spot on the wall must line up with the valve to keep the wheel in balance.

Periodically the tyres should be inspected with the object of removing from the treads any sharp Hints or other foreign bodies which may have become embedded in the rubber. Their removal is made easier if the tyre is partly deflated before attempting to prise them out.

Damage to the tyre casing and the tube may often be avoided by the removal of these potential puncture makers.
