When you're driving - whatever the speed or conditions - your only contact with the road are the four postcard size 'footprints' of your tyres. Statistics show that almost half of all car accidents are caused when a car skids - tyres are your vital link with the road and it pays to have the best fitted by our professional, qualified tyre fitters.
What function does the tyre tread perform?
The purpose of the tread on tyres is to allow the tyre to grip in the wet. Huge volumes of water on the surface of the road have to be squeezed out by the tread grooves. For example, at 60mph, with a water depth of only 3mm, the tyre has to clear over 2 gallons of water per second!
If this water is not rapidly dispersed, the tyre will begin to "aquaplane" - a sheet of water builds up between the tyre and the road - and the tyre loses all contact with the surface of the road.
This is exceedingly dangerous. The capacity to disperse water is drastically reduced with low and worn tread depth - so carefully monitor the depth of tread on your tyres - YOUR LIFE could depend on it.
What is the legal limit?
These levels represent the absolute minimum and tyres as worn as this should be replaced immediately.
To help you judge how much tread you have on your tyres, manufacturers often mould tread bars at roughly 1.6mm. If you can see these bars your tyres are about to become illegal and unsafe. Recent research conducted by the independent automotive research and testing centre, MIRA, has proved that there is a significant deterioration in wet braking distances when a tyre wears below 3mm.
