Uniform tread wear and the remaining tread depth are two important tire conditions that play an important role in the safe handling of your car especially during wet weather.
The amount of water that can be squeezed out from under the tire is better with a tread depth of 8mm compared to a tire that has only 1.5mm. In other words, the more the tread depth, the better the water scavenging efficiency.
Keeping that factor in mind, let us now look at another varying factor that affects the water dispersion from under the tire affecting the degree of contact.
If we can all agree that in order for safe maneuvering and braking of the car, there must be sufficient tire and road contact, failing which the car can go out of steering control due to hydroplaning.
The speed of the car hitting a puddle of water is the other important varying factor which determines the degree of tire and road contact as illustrated in the diagram. The better the contact, the safer the driving condition.
From this illustration, we can see that the best tire and road contact condition can be obtained with more tread depth and with lower speeds
In conclusion, when driving in wet road conditions, ensure that the tires are in good condition with at least minimum tread depth and of course, driving at lower speeds.
Avoiding getting into a dangerous hydroplaning situation is better than getting into it and then trying to correct the situation.
