this might explain why do our cars hydroplane...

Anybody know what type of tyres that can reduce this hydroplaning? Got the car for two months and had my first planing which was a very scary experience could have been in a serious accident.

Holy old thread. S03's are less prone to hydroplaning than S02's. Or you could just slow down when it rains.

Thanks for the advise. I was just not prepared for the experience, just more aware of it now.

Your MY06 comes with RE050 and it is better than S02 on the wet. Also, do not turn off the VSA while driving on wet roads.

I should have looked at what year he was driving.

Westside Billy is right. "Hydroplaning" isn't drive error, this probably occurs every time you drive in the rain whether you notice it or not.

I think it is pretty damn obvious why the S2000 is a little more prone then some cars. if it isn't you should take a physics class.

most cars are pretty predictable in Hydroplaning conditions if you are a good driver.

even if you slow down you still might hydroplane you might not notice it but you probably will.

and besides the people that say S2000's hydroplane very easily are probably comparing it to the 1 or 2 other cars they have experienced this in.

[QUOTE=WestSideBilly,Feb 27 2002, 08:58 AM]Hydroplaning is the act of a tire losing grip with the road surface due to its inability to siphon away the water between the road and the tire's contact patch.

Haven't you learned by now that in this forum any handling problem with the S2k is "the stupid driver's fault"
If you say otherwise you must be "smoking something"
I guess I drive too mild mannaredly to notice them, so could you explain the handling problems with the S2k. I don't want to hurt myself because I've overlooked something important.

Hydroplaning is the act of a tire losing grip with the road surface due to its inability to siphon away the water between the road and the tire's contact patch. This is a result of five primary factors - the size (width) of the tire, the tread design, the weight and speed of the vehicle, and the amount of water on the road. Basically, if the amount of downward pressure (determined by vehicle weight and tire width) is less than the amount of pressure needed to force any water aside, the tire will hydroplane. Speed factors in by affecting the amount of time the tire has to push aside the standing water - going faster means more water to push aside, which in turn results in a greater liklihood of hydroplaning. The tread design is a major factor in how effectively (quickly) the water can by siphoned away - the grooves in the tires benefit you in two ways, they reduce the contact patch (increased pressure) and give water and channel to exit off to the side (reducing the needed pressure)(Aquatreads work well in the rain by giving a 3rd escape route, down the middle, in addition to going left or right, further lowering the required pressure - however they can still hydroplane if you drive too fast through too much water). S02s are designed to siphon off a small amount of water, but at a fairly high speed - the tread design is similar to that of an racing rain tire. Bald or nearly-bald tires hurt rain handling because they have a larger contact patch (less downward pressure) and no channels for the water to escape (more pressure needed).

So why do S2000s hydroplane? A fairly lightweight car, on wide tires designed primarily with dry traction in mind, with only minimal water channeling. Go too fast in the rain, and voila, you hydroplane. If you don't want your S2000 to hydroplane, either slow down, or buy 5" wide tires.

As an aside, hydroplaning does not discriminate. I've been in a 70,000 lb semi that was hydroplaning - not fun! I've also been pulling a 3000 lb car trailer that was hydroplaning all over the place, even though the 4500 lb vehicle pulling it wasn't. Not quite as bad, except I kept envisioning the trailer sliding into the adjacent lane and taking out some poor sap in a geo.

We've got some problems with physics and consevation of mass...going faster does not make "more water to push aside." As you correctly assert, speed affects "amount of time the tire has to push aside the standing water." So, the faster one goes the less TIME you have to remove the water under the tire. The type of tread pattern and depth of the rain channeling grooves will affect this, as long as the tire is going in a straight line with no changes in speed, and no directional changes the tire will behave as advertised. As this is where driver in-put comes into play: a sudden drop (or increase) in speed or an abrupt steeing input (all of which can happen on the highway with standing water) can defeat the hydrodynamics of the rain channels in the tire (assuming the driver isn't already going too fast for the tread characteristics and road conditions). A layer of water then separates the tire from the road surface, and voila, no more traction.

Bottom line: if you drive in the rain with tires that have little tread depth (or are meant for dry conditions) you run a significant risk of hydroplaning. Also, different tires perform differently in the rain, so SLOW DOWN in the rain and have fun when it dries out

LOL, well, I'm confused NOW, because you quoted someone else, and then addressed me. Can you be a little clearer with regard to the comments you are actually addressing? I didn't say any of the stuff you think I'm confused over, so I'm wondering who it is who is actually confused. Me for sure, but I think that may be your fault.
