These tires perform fine when dry. Does it's job very well in snow. My RX8 was able to get around in over 12 inches of snow. These ride well and are not too loud/rough as well.
However, on wet and ice these have been a nightmare, I've spun out twice, once going 40km/h on ice, the other going 50km/h on a circle highway on ramp. I get wheel spin big time and RX8 although RWD it doesn't even generate that much torque. Well I still haven't gotten in an accident so it gets a fair score.
