hydroplaning

[George Harris]

Somebody should tell the manufacturers to stop wasting their time 
designing all those tires with special wet weather handling 
characteristics. Wait, ... is all my driving experience wrong? Of course 
water flows under pressure. Yes, even a well designed tire will 
hydroplane. The discussion is will a well designed tread hydroplane at a 
higher speed.

Show me the experiments that prove my 42 years of aggressive driving 
experience in all sorts of s**t weather with all sorts of tire treads is 
wrong.

Cheers
