Tyres - am I being stupid?

[therealpigdog]

Just bought a set of four Avon ST Ice Touring tyres on steel wheels and think I might be going mad.

The tyres are asymmetric with a large groove on one side - do far so good as all mounted correctly, but from the tread pattern it looks as though I have four left tyres as the tyre appears to be directional.

Is this the case, or am I going mad? Can you have asymmetric and directional tyres (and are these them)?

Cheers - will unpack fully in the morning - it just looked odd, but those dunlops have reassured me.

just need snow now!
