The tyre tread is one of the most important components of the tyre and the appearance is often one of the deciding factors for people buying a tyre.

The tread has to transmit the forces for acceleration, braking and cornering from the vehicle to the road surface to provide the necessary grip.

As most vehicles weigh in the region of 1500 kg and are capable of speeds well in excess of 120km/h, it is evident that a tyre is one of the key safety features ensuring a safe journey.

The tyres most noticeable feature is the tread grooves.  Contrary to popular belief, they do not disperse the water from the footprint but are designed to hold water in them in order for the raised portion of the tread to make physical contact with the road.  At speeds of around 120km/h, there is no way that the water will channel itself through the tread grooves and come out the side.  To give you an idea as to how much water the tyre would have to process at 120km/h, consider the depth of water at 2mm and the tyre size of 205/55 R16.  Each tyre would have to process nearly 12 litres per second – the equivalent of running your garden hose at full blast for 6 seconds.

If the depth of water is too much, the depth of the tread too little, or the speed of the vehicle too high for the tread grooves to process this water, then aquaplaning will occur.  The tyres lose contact with the road and the rest is history.  It is not surprising then, that tyre dealers can do good business the day after it has rained. 

At BestDrive Auto Tyres we recommend that you check your tyres regularly in the interest of your own safety and that of the motorists who travel our roads daily.
