Most people don't drive in circles and accelerate looking for the point where traction is lost? And I would guess that most people would not encounter those lateral G's (whatever they were, who knows?) at hydroplane velocities But there's more and better (duh), if not great, evidence that I might be wrong. http://www.canadiandriver.com/articles/pw/laurens.htm (Them's got pichurs, altho they fail to mention in which position the tire is mounted when photographed).

No, it's been said by just you. Ya know what, go put your better tires on the front, go knock yourself out. It's your vehicle, it's your life. Put tires with less traction ability on the rear, see what happens to you. Just don't kill anyone else or bend up their vehicles when you spin. >>Wipes or no, the rear can still break loose and come around. > Of course it can.

Oh that's right only I have to cite my views. What percentage less water do rears have to face? What about when you turn or change lanes when your rears aren't following in wipes exactly? |

Drive a mustang in the snow sometime. Let me know if you find the limits of worn tires. |

Too bad that front and rear track widths negate some of the wipe, that tires don't really "wipe" it anyway - all-season tires are required to have 25% empty space. Too bad that you haven't driven an Acura NSX with legal but well-worn rear tires in the rain and experienced oversteer conditions due to hydroplaning. Too bad that everything you've said is utter tripe and contrary to what every expert says. FloydR |

It's *doubly important* to have grippy tyres on the rear of a FWD car because of the issues of lack of control that occur if the rear 'steps out' ! It is not by any means about the rear tyres just 'following around' at all. Graham |

That is understeer, unless you're not trying to turn. Most untrained drivers instinctively let off the throttle when it happens. Since that results in loss of speed as well as some degree of weight transition to the front, the front tires regain traction. |

I guess I was assuming that the hydroplaning was ocurring on a straightaway, since the OP was here to ask us about it nate -- replace "fly" with "com" to reply. http://home.comcast.net/~njnagel |

Roads do curve and bald/low tread rear tires 'will' float out faster than you can blink.
