We recommend checking tyre pressures every fortnight, not forgetting to check to spare as well. This should be done when the tyres are cold, as the pressure in a tyre will increase as it warms up. The pressure settings when the tyres are cold should always correspond to the recommendations given by the vehicle manufacturer or tyre company. You should pay particular attention to any abnormal conditions of use, e.g. full loads, towing a trailer etc. In order to protect the valve and ensure that the tyre pressure is maintained, we recommend fitting a valve cap with an air tight seal.
Driving with tyres at incorrect pressures is dangerous. Under inflation causes heat to build up in the structure of the tyre, which can result in sudden and rapid deflation. This can happen some considerable time after pressures have been corrected.
