They look exactly like my original Toyota hubcaps. Without instructions, it took a few minutes to figure out how to attach the guy wire. There are two tricks: You have to twist the U-shaped piece of wire so it fits into the 1/2" round indentation on the cap. (This makes room for the valve stem.) 2 in. The U-shaped part of the tension wire should be facing you (not the wheel) and placed on top of the cap to make room for the rubber valve stem.With the wire stirrups in place I was impressed at how nice and snug they sat on the handlebars.I have another set for my Subaru and made the mistake of hitting it with a rubber mallet when it was cold, don't do it they will break, if you remove them in the cold use two large screwdrivers with both hands and move them at the same time to free them not to break or split.Moving most of them at once makes them less prone to breakage.If you put them on cold, rub them with your hands.
