Had em off this morning and it seems I have Hankooks on the front and some other Tingtong make on the back. The fronts look the same as when they were fitted and the rears are nearly bald. I guess it was the rears that were sliding about, but I did suffer with terrible understeer and 4 wheel drifts on wet roundabouts, so the fronts weren't a lot better. I'll be getting the Contis that won all the tests this year instead.
The Hankooks had a 300 in the model number, but not at home now to double check...
