Preupdate XJ oem lug nut size
Something that I haven't done for a while, is check the tightness of the lug nuts on my oem 15" Jeep Steelies. The reason for checking is that I could hear noise from one of the rear wheels. I found a loose nut and tightened it. Then I decided to check the others.
I got to the last lug nut on the front pax side using my Jeep supplied onboard 19mm wheel tool and to my surprise, it would not fit over the nut.
I then checked it with my wheel brace (which lives in my garage) and a 21mm socket was needed for that last lug nut. Great, I thought. That would have been an unnecessary call-out for road service if that tyre ever got damaged. If I was in the middle of bugger all, that could have been a problem (without the brace).
Over the years, many of the original lug nuts have worn, and been replaced by basic 19mm open ended nuts.
I am thinking of getting some new replacement oem style lug nuts to put on all 4 wheels. It's the detail that matters.
What is the size of the default oem lug nuts on pre update models with the sport 15" Steelies?
Is it 1/2 - 20 (3/4 Hex) for the 19mm?
I think the 21mm converts to 13/16 Hex.
