driving in the rain or over standing water and you temporarily feel the
vehicle is no longer in control this a result of hydroplaning or some
would also call it aquaplaning. This incident normally happens when a
layer of water builds between the tyre and road which then causes the
vehicle to swerve around like a sled.
Hydroplaning is caused by a combination of factors
which incude the speed the tyre is traveling how much tread is remaing
on the tyre, tyre pressure and also the depth of the water. When the
tyre travels over the water it creates a blocking point similar to a
wave albiet very small this cuases the tyre to temporaly float on the
water hence loosing contact with the road. This is hydroplaing, to lose
in lose traction and glide or hydroplane across the water.
On wet roads when tyres if a tyre has good tread depth
and the tyre pressure is correct you will avoid sliding and hydroplaning
because the grip and pressure allows the tyre to cut through the water.
Where there is little tread remaining or the tyres are under inflated
can cause hydroplaning at very low speeds.
If the tread wear is blow the legal limit of 1.6mm, and
you are driving at high speeds you will experience loss of grip due to
the tyre not able to disperse water properly. This will cause major
loss of traction. Loss of grip especially wet roads can be fatal and
cause the vehicle to spin or slide.
