I ran a set of these on the rear of my E90 but was extremely disappointed with the mileage!!! I bought them last year as dedicated summer tires and with only 7-8K miles (roughly 12,000 km) they are completely worn out!!!! Granted I don't drive like a grandma all the time but when compared with DWS's that I had previously these lasted about a 1/3 as long. Not impressed especially considering I had to get these replaced after a week under warranty because the first set wasn't round. In my personal opinion Conti's have let their quality control slide over the years as also evidenced by a recall on my front motorcycle tire on my BMW S1000RR motorcycle. My $0.02.
