I got my car inspected today and when they phoned one of the things they told me was I have swollen lug nuts. (???) They mentioned it could be a problem if I had a flat out on the road. I had never heard of such a thing.
Anyway, this evening I took a few of the lug nuts off and examined them. I was surprised to find they are a two-part design with a chrome cover pressed over a steel lug nut. I hadn't noticed that before. And yes, there appeared to be a fine line of corrosion at the joint between the two. So I measured them with a caliper. And yes they are about ~.005 to ~.010 over the nominal 3/4" hex. Surprise, surprise, I do have swollen lug nuts, but just mildly swollen.
Ah, all my lug nut wrenches (including the emergency one in the car) fit on the lug nuts. I'll keep an eye on it.
The garage I go to is very sharp, and very picky. OK maybe they were looking for an up-sell, but I can't blame them for doing that. Swollen lug nuts, who would have thought?
