Fitted to and E61 530i - Awful tires.
Wasn't told by the tire shop that they were summer tires, so that's partly to blame - but terrible regardless.
Grip is non existent if below 5 degrees or so, meant to be used above 7 degrees only, but even then they're poor. Stuck the back out on a roundabout lightly accelerating when temps were about 12 degrees.
In the wet theyre just as bad. Its now almost summer and wheels span in the rain whilst accelerating on the motorway.
Been on for about 50 miles and im already going to replace them.
Side note - just me in the car - wouldn't even use them temporarily with the kids in it. Surprised they've even passed safety standards
