The result is that you are likely go into uncontrolled
hydroplaning at freeway speed with even a light rainfall, and the vehicle may be unusable in moderate to heavy rainfall unless you drive very slowly.
These tires are better able to handle heavy rainstorms and slushy snowfall by actively pushing water out to the sides of the tread area as the tire rolls forward, minimizing the risk of
hydroplaning at high road speeds in heavy rain.
The main risk of insufficient tread depth in rain is
hydroplaning at speed.
In these conditions, the 265 - section - width front tires
hydroplaned at only 70 mph, and the 365 - section rear tires also experienced grip and traction problems.
Not exact matches
For example, when a normal tire travels over water
at a high speed, pressure builds until a film forms to lubricate the interface; this is called
hydroplaning, and results in a complete loss of frictional control.
Not only will the rain impair visibility and make cornering and braking more difficult, but the introduction of large puddles of water throughout track also bring the risk of
hydroplaning into the mix — as I discovered shortly into my first wet race
at Sebring where my RX7 careened into the concrete barriers moments into the event.
Inspect all tires to make sure there is
at least one - eighth of an inch of tread depth for safety and to help prevent
hydroplaning on wet roads.
Thankfully, the Turbo brings bags of grip and retuned stability control programming to the party, and despite 20 - inch Pirelli P Zero tires that are a half - inch wider than last year's Turbo (9 inches wide up front, 11.5 inches
at the rear),
hydroplaning was manageable.
If you want to avoid
hydroplaning, it's best to avoid driving right
at the beginning of a rain shower, as that's when the roads are the most slippery.
