I think they're the SC3s.
Both the SC1s and SC2s are marked as such with a small coloured logo on the side of the tyres. I don't think that the SC3s are marked at all in this way.
Someone did say there was a SC4 - but I'm not too sure. But I reckon you should avoid these anyway!
Tyreman - one for you I think!!
