Just had my club buy Pirelli corsa tyres mounted to rims. They have been mounted to the rims correctly with the outside facing out. The strange thing is the tread is not the same direction on left and right tyres even though both outside faces are correct, do I have two lh or rh tyres? Anyone else noticed this. I'm not sure if the tyres are meant to be handed from Pirelli as the tread is directional. Maybe someone in the club had two of the opposite hand? Wet grooves on inside are opposite directions.
Graham,
This photo would suggest that there isn't a right (or left) version of the tyre, just one version only:

Looks like they are bi directional..... I have viewed images and cannot see any directional arrows on the side wall.......... but like you Neil I thought they would be "directional" by just looking at the tread pattern
The P Zero road tyres are similar with an Outside marking but not a left or right.
Seen this with uniroyal rain masters too very odd
It's an asymmetrical - not a directional - they just have an inside and outside rotation is not important.
I will have to see if such a thing as asymmetrical directional exists

The Pirelli Site says ......
The exclusive tread of the P7™ CORSA Classic incorporates two specific designs: slick for dry conditions and grooved for the wet, drawing on and developing the asymmetrical pattern that has characterised the very best Pirelli UHP tyres.
So they are asymetrical....
Still not totally convinced Pirelli should have made them directional. Think it just a way of reducing tooling, costs and logistics. The inner wet tread is Probably not a big player on water removal as its only on the inner section and it's not really a tyre for the wet.
Still a few miles on them and there won't be too Much tread pattern to worry about.
Thanks to all for doing some digging.
