Tyre direction / tread pattern ?

[gareth h]

I've just had a set of Dunlop Qualifiers RR fitted to my Tuono, refitted the front wheel (obviously without checking the arrow for rotation!) the wrong way round.
If you think of the tread pattern as being an arrow head I would normally expect the point to meet the road first so that water is forced out to the edge of the tyre (which is what happens with the rear).
This tyre is the other way around, the tread pattern at the edge of the tyre meets the road first, which looks like it would then force water back towards the centre of the tyre.
Tyres look like this http://www.dunlopmotorcycle.co.uk/tyres/ranges/roa...
Anybody know why this is?

Yep, I know the arrow is definitive, the thing I found interesting was the tread pattern being 180 deg different to the rear.
Point taken about being cranked over, but if that was the case you would expect the rear to be the same.
