Once bedded in these tires really come alive. Very sticky (you can hear all the stones being picked up off road and flung against the underside of your car) especially when they get warm.
Cornering is good, the tire walls are hard but you do get a slight wobble when you don't drive smooth round corners. Traction off the line is superb also.
In the wet they are ok as long as you drive like ms daisy. Do not push your car in the wet with these on and ESPECIALLY do not drive if it has been raining for hours and there is standing water.
