Yokohama Avid S33 Tires at these higher
air pressures do not appear to have any additional
tendency to  hydroplane. However, the higher
air pressure means that the tires transmits
more shock from road irregularities  than if
the tires were set at alower air pressure.   I've
only recently upped the tire pressure but I have
not notice any problems with traction or handling;
however, since I am driving this Prius for fuel
fuel efficiency - I am not testing the upper limits
tire's handling characteristics or its braking
performance as might another.  Sofar the tire
treads doesnot appear to be wearing out prematurely
or wearing out in an irregular manner -- however
I will keep an eye on this possible complication.

Reviews suggest that this particular tire has a
lifespan of about 20,000 miles - so I am expecting
to replace them in the next two years with something
better.    I've read some negative consumer reviews
that complain  that the Yokohama Avid S33 Tire
have poor snow and ice handling. Earlier this
year the Washington DC area was hit by a
big snow storm - but unlike certain northern
areas of the USA snow storms are a rarity
for this area - so I am unlikely to have a chance to
test this tire's actual snow and ice handling
characteristics before the tire tread wears out

You won't be hydroplaning on snow and ice, skippy.

You will be skating.

The Yokohama Avid S33 Tires are designed for
only light snow - they have only fair snow and
ice traction performance.  Because, snow
and ice are a rarity in my area - it may not be
an issue for me since reviews of this tire suggest
that they are not likely to last more than another
18 months.  When I get replacement tires I am
thinking of getting Hankook Optimo H727,
Consumer Reports ( July 2010, page 50-51)
reports they have very good snow and ice handling

And worse to none at those tire pressures.

And you are talking out of your ass if you think the higher pressures
have much effect on traction in the snow.  I have been getting around
just fine in the snow here in NH.
