Unlike other eyebolts, these BMW X1 eyebolts are not tight and are actually loose. So they are back, I think they would just fall off during use. They fit exactly with the eyebolts I got from TireRack for my winter tire/wheel combo. So the product is fine as long as you don't use the eyebolts that come with the BMW wheels. At 17mm this is a strange problem. I haven't done a detailed analysis, but I think it has to do with depth when pressing on the eyebolt.
