I'm having an issue with the front lug nuts on my 1927 coupe. The issue is I can't get them to tighten up? No matter how I try, the lugs never seem to bottom out. The rear lugs seem to tighten but also do not want to bottom out. Is this the norm or should I be looking for new lugs?
Check the threads on the hubs.If they are stripped,you need to replace.
I am assuming your problem is that the nuts tighten up, but the wheels are still loose. If not my following explanation doesn't fit your problem.
If they are repro lug nuts, they may not be made correctly. The threads on the nuts should not start for the first 1/4" of the nut, as the studs are not threaded all the way to the end. You can fix this easily on a lathe (fix the nuts, the studs are made that way!).
This has been a known problem with model A lug nuts, wasn't aware of it with model T ones.
I think I know what you mean, I checked a couple of my T's and some lugs are thick and bottom out on the wheel/felloe and some have a thin lug on the rim and do not by about 1/8" I've never had a problem with them, just tighten up evenly so the lip on the rim is sitting nice on the wheel felloe.
This is a26/27 wire wheel problem, so not about the fit between felloe and rim on wood wheels.
Fortunately the hub bolts and the lug nuts are available if needed. I've bought them new in recent years and they worked fine. But if the hub bolt threads are OK, there's no need to change them out - it's a bit of a chore that needs a special tool and a press if done factory style. Most seems to add a bead of weld on the back side to hold them instead of swedging, though.
Wire wheels and hubs are often damaged from years of overloads and neglect on haywagons, so careful checks for any cracks are necessary. Most can be welded. Sometimes the lug bolt holes in the wheel are worn oversize with small cracks from the hole - that may also cause the situation George describes?
If the holes are only moderately oversized without cracks, these washers may help? Their main purpose is to save the paint on the wheels:
