Purchased a used Sheriff's department Police Interceptor with these tires, and have approx. 1,000 of my own miles on them during October and November during the beginning of our legendary rainy season.
Grip, road feel, and steering response are pretty good in the dry. Hard acceleration from a standing start the (rear) wheels spin despite factory limited slip, but that could be the weight distribution of the car.
I have already experienced some wet cornering traction issues, which is a problem in Oregon. The amount of rain is approx. 50 per year, and I suspect that much sustained rain means that most of the road oil is pretty cleaned up by it already. Thus, I think that wet cornering is pretty poor and a car without traction or stability control could be a handful to the uninitiated.
In addition, depending on the quality of the road surface, the tires can be either quiet or pretty noisy, and the 260 treadwear rating means that it won't live long.
They'd work in Southern California, but here, not so much. Great in the dry though.
