These were the OEM tires. After only about 18,000 miles, they need to be replaced, but I will not be getting these tires again.
While I enjoy spirited driving on occasion, most of the time I am commuting at normal speeds, and cornering in normal traffic. Therefore, there is simply no excuse for the high rate of wear these tires experienced.
The performance of the tires themselves was average to moderate for this type of tire. In other words, there was nothing to recommend them. Wet traction and stability was notably poor.
These tires are, within their category, amongst the highest price. I found that neither their perfomance nor their tread life justified their purchase.
