It is vital that you know the condition of your tyres and the tread depth especially so when there are wet conditions.
As a general rule a new passenger tyre has to displace app 10 litres per second at highway speeds and the tyres ability to do this decreases as wear takes place so in heavy rain a worn but still legal depth tyre will be unable to displace the same amount/volume of water as when new needed to maintain full contact as wedge of water will build up in the front of the tyre and may/will depending on speed and the amount of water on the road surface lift the tyre completely off the tarmac where the driver will have no control and become a passenger .This is called aquaplaning and the driver must lower the speed to regain control.
This can still happen with new tyres depending on speed and conditions.
All tyres are round and black BUT there can be a wide variation in grip,levels due to Treadwear rating as the lower the number the better the grip but won't last as long as a higher TW rated tyre that will last longer but will generally have less grip along with.the tread pattern which also plays a major part as well and the better known brands will generally perform better than a cheap/budget priced tyre made in some 3rd world country
