quattro+rain

[Benjawan Kuecharoenwong <u3520170@au.ac.th>]

	Today I drove my dad's S4 to the univeristy ,I drove to highway
and then the rain started heavily,I used highest wiper speed and turn on
fog lamp. I found that around 62 mph the car start to aquaplaning
(am I use the right word ?) I think 235/45 tyre play a major role here.
	I don't expect aquaplane in the quattro system,but it's ok ,the 
car still go straight while aquaplaning,doesn't like my MB which ride
on wide tyres (225/45)too,MB also aquaplane on this road when heavy rain,but
when it did ,it head seem to change direction,so AUDI is better in this 
respect.
