When new, they feel fine, just like any other new tyre. As soon as they are getting within 4 or 5 mm of the wear indicators, they start to get noisy and this only gets worse. At low speed, they jitter and rumble; over about 50 a whine like a failing wheel bearing starts and gets worse the faster you go. They also tramline somewhat, and feel somewhat sketchy in turns (once again, only felt once worn).
On the plus side, they give fantastic grip in the wet, but this does not make up for the abysmal wear characteristics and the noise. The rolling resistance is higher than for most tyres; this'll cost you a couple of percent of your fuel economy.
Overall, avoid these tyres. The wet grip isn't worth the other downsides; they don't even last particularly well.
