These were fitted to my 2007 Kia Cee'd 16 CRDi when I bought the car at 80,000 miles. After 3 years and 30,000 miles they are down to 4mm all round (after being rotated front to rear to get even wear) which I think is pretty good life span as I generally don't hang about. Grip is good in both wet and dry, and handling seems fine. Dislikes include road roar and that they are directional which is a pain when I came to rotate them. Additionally, there is now quite a lot of cracking between the tread which concerns me.
