querry on Michelin Pilot tyres

[steveH]

Hi, hope someone can give me quick clarification.
Should the Michelin Pilot road tyres be directional??
I have bourght set of CSL alloys & tyres from Quarry and looking tonight at the tyres there tread patterns are the same when faces of alloys face same way and with no directional arrows. So when you imagine wheel on both sides of car the tread pattern is reversed which means they will dispell water in opposite direction on one side to the other and this looks wrong to me, but being non-techno thourght some of you will advise.
Hope this makes some sense.
