RE:Hydroplaning

["Gary Barry" <Gary.Barry@trw.com>]

Interesting debate.  This will be my last post on this subject.
Consider that the equation only holds when the water is deeper that the
tire tread.  Is tread design effective in this situation?

I sent the following on Friday, but I think it got lost in the mail:

I am not an expert in this area.  Here is the editor's note (the only
letter with an editor's comment):  "According to this member (of USAA) -
and several others who took the time to share this same information -
if, for example, your tire required 36 pounds of pressure, you would be
at risk of hydroplaning when you exceeded 54 mph (6 x 9) and the water
depth was greater than your tire's tread depth."

The tire pressure (PSI) is used as an absolute value without units with
results defined as mph.  By the way, if some of  the list members do not
know, USAA is a large, highly-rated insurance company which used to
insure only military officers and recently has started issuing policies
to the enlisted
ranks,  Not a commercial!

Enough said.  Onward to other subjects.
