Well I'v never had any problems on any of my bikes nor my customers bikes.
Maybe "as tight as you can" isn't quite right though. I wouldn't say you'd want to be going blue in the face with the effort you're putting in to tighten them or be moving your stance so you can force them tighter but I think I generally horse them up till they don't go any tighter as opposed to the likes of a stem bolt which is much more about "feeling" how tight the bolt is than tightening till you can't go any further.
