I just put my winter tires on, and I noticed that the front lug nuts don't seat all the way down the lugs. They only grab about half the threads on the nut. I assume the lugs are a little short, but they seem to work with my summer rims. Is the distance that the lug nuts go down on the threads safe enough? The nuts are about 1" in length, so they grab about 1/2" inch of the lugs. I'd grab a pic, but with the snow right now, I don't want to wreck my digi cam.
