I had got these tires with the car with about 80% tread left on them. Have to say a very noisy tire. They also have a low speed thrum which vibrates through the car. They have a hard ride too.
On the plus side the tires have a very high level of dry grip and only acceptable wet grip. Example of this is when I went around a corner marked for 70km/h at 140km/h without any tyre squeal and flat handling. Dont try that in the wet though as these tyres just let go rather than scrub out in the wet.
I replaced them with a pair of cheap Chinese made Rotala autogrip tyres size 275/45 20" which I got for $130 each fitted (Australian dollar). In comparison they give an unbelievably soft ride but squishy indirect handling due to their very soft compound. (I'd personally rather that though as I dont like to push hard in most driving)
In summary a very good performance tire that comes at the cost of comfort.
