Any vehicle can hydroplane irregardless of the weight. Hydroplaning occurs when a tire encounters more water than it can dissipate. Water pressure in front of the wheel forces a wedge of water under the leading edge of the tire, causing it to lift from the road. The tire then skates on a sheet of water with little, if any, direct road contact, resulting in loss of control.The likelihood of hydroplaning increases with the speed of the vehicle and the depth of the water. Tread wear and underinflation also increase the risk for hydroplaning, as do wider tires. Narrower tires are less vulnerable to hydroplaning because the vehicle weight is distributed over a smaller rubber contact patch, resulting in a greater ability for the tires to press water to the sides, allowing tire contact with pavement.19inches said:I believe tire treads matter, but given the bulk of the Acadia, can it still hydroplane?
Not to pick nits, but the engineer in me seeks a bit of clarification on this. The contact patch of a narrower tire is not actually smaller, it is only narrower, but longer. Without getting into the physics of a pneumatic tires, if the weight of the vehicle, tire pressure, and general tire design are equal, tires of different widths will have exactly the same tire patch contact areas in square inches and the force to the ground (in psi) through any of those square inches will be exactly the same. The narrower contact patch will just be longer. There are two basic reasons why the narrow one will hydoplane less. One is that it encounters less water (to be cleared by the tread) to begin with, and also because the patch is longer in size it has more time (more travel in the circumference) to clear that water.Snoguy said:Narrower tires are less vulnerable to hydroplaning because the vehicle weight is distributed over a smaller rubber contact patch, resulting in a greater ability for the tires to press water to the sides, allowing tire contact with pavement.
I did not notice any notifications on the dash or HUD. I really wasn't really concerned about what the car was doing at the time, just where it was going and how I was going to stop it.rbarrios said:when you began to spin and where in it-- any signs of stabilitrack kicking on?
I know the situation didnt lend itself to you paying attention to the DIC.
Yes it can. If i was distracted or not paying attention, I can only imagine how bad this could have turned out.capecodacadia said:You could hydroplane a tank under the right circumstances.
Any vehicle will hydroplane if the driver isn't paying attention to road conditions.
It certainly was not a hydroplane like I have experienced before in any other vehicle. The car felt like it simply disconnected from the road, just like on a large patch of black ice. Could have just been the the perfect condition for this situation. I am convinced it could have happened in any vehicle.Speleos said:Question is, urbanburban91 - were you really 'hydroplaning,' or had you fallen victim to 'slippery when wet' road conditions. There is a difference.
I was wondering if it stalled of just shut off. I can see it stalling in this situation.Speleos said:btw, it's a natural tendency for an engine to stall if your going in an opposite direction from what the gear selector is set - like in a spin.
I plan to call my dealer tomorrow AM.GMC Customer Service said:First off, let me begin by saying, I am very glad you and your passengers are safe.
Since you experienced the traction control light coming on and off once you got back on the highway, do you have plans to have the vehicle to the dealership to have this looked at?
