When motorists are out driving on and off the roads they forget that the only bit of contact with the ground below them that they have is between the surface and their tyres. Tyres look quite large when you see them, but the amount that touches the road is roughly the size of a postcard! This is why it is essential to have the correct type fitted and that they are in the best condition possible, especially so during the cold weather months.
When learning to drive, everyone will learn that the legal tread depth requirement is 1.6mm in a continuous band across three quarters of the centre of the tyre. When one gets to this stage it will need to be replaced immediately. If possible change it before this stage, especially if colder weather is about to hit. The deeper the tread depth the better they will give you grip on the road, which is essential to prevent the car from skidding. Many car accidents are caused when cars skid out of control which can be down to poor quality or worn out tyres. Tyres should be fitted by a professional. Of course if you are a car mechanic yourself and are able to do it easily yourself from home that is fine, but if you are unsure or just for ease it is best to take it to a garage.
Most tyres typically begin with an 8mm tread depth and people usually change them once this is worn down to about 3mm to be on the safe side. There is various ways to check the depth. Modern day tyres usually have a wear bar on the tyres; the raised bars are visible in the tread lanes and once these become level then they need changing immediately, especially so if they are below them! You can also use a 20p pence, you stick it in various tread lanes on the tyre and if there is a raised edge of the 20p piece visible then they need changing.
Make sure to add inspecting your tyres into your regular car checking routine. Your braking distance will be seriously affected if the tyres become too worn. You would not walk around with holey shoes that were worn out and it is even more important that your cars 'shoes' are fit for purpose so you can drive from A to B knowing that the only thing touching the road is of a high quality.
