Tyres are the most important aspect of you car. There are several checks that  need to be regularly carried out to prevent damage or excessive wear. At least once a month you should carry out the following checks :

• Tyre pressure 
• Tread depth – the legal minimum is 1.6mm
• Bulges or cracks in the tyre
• Uneven wear

You can adjust the tyre pressure yourself at home or any petrol station, but if you notice any of these other issues then you will need to replace your tyres straight away.
