Completely stupid. They don’t make the car handle or grip any better,
except, perhaps, on a racetrack in the dry. They rob the steering of feel. They aquaplane more readily in the wet. They give the car appalling ride quality. And they break when they hit a pothole or road hump, which is very likely given the terrible state of many British roads. That meets my definition of plain daft. Some owners of BMW coupes with 19” wheels that have cracked are using small claims to try to sue BMW for supplying wheels of “unsatisfactory quality”. The trouble is, the customers have specified these wheels for whatever reason. All BMW has done is give them what they wanted.
