Checking your tyres for damage, tread and inflation should be something everyone does on a regular basis. Having under inflated tyres can not only cause uneven tread wear and loss of fuel economy but can also lead to a serious accident. If you are unsure of what the correct tyre pressures should be then refer to your car handbook or contact your local dealership to find out. You may find that some cars require more or less air in the back tyres than the front, so does not always assume that they should be the same around. If you are constantly having to pump one of your tyres up then you should get it checked immediately as it may be that you have a slow puncture, or even that the rim of your wheel is damaged letting air out, in which case you will need to replace the wheel itself.
