Proper KO thread orientaion?
Car in question...66 SB convrt.
Question:
I've got repo KO wheels. Been on the car 20 years. I have safely used the car for the past 10 years.
Just got new repo goldlines, and wanted to clarify one item prior to reinstall.
Which way should the "off-arrow" be pointing on the spinner?
Again, I've been using the car safely for 10 years with the "off arrow" pointing towards the front of the car.
This curent set-up is contrary to my intuition... that is the forward rotation of the tire should cause the spinner to tighten on itself, and as far as I can tell, my current set-up is opposite. The spinner comes "off" going towards the front of the car.
I would think that you'd want the spinner to come "off" towards the rear of the car so that while it's in forward motion it's tightening on itself????
Thanks in advance!

Well let me take a stab at this..... It's been beat to death here and I have recently installed a set of knock offs - no safety pins.
A properly installed set of KOs should not be effected by rotational loosening. (OK, nows the time somebody will take exception with this)
I put my KOs on so that they tighten towards the back of car. (Therefore on the drivers side they turn clockwise to tighten.) BUT the most important thing is to get them seated (rims against the adapters) properly and use a good old fashioned 5 or 6 pound lead hammer and beat the be-jesus out of them - well at least 8-10 good hard wacks
I marked my spinners with a sharpie marker and have been 250 miles and never seen a bit of movement (as in loosened spinners) I have tried to add additional wacks to tighten them and they are as tight as they will go. I even backed off the spinner, took off a wheel and re-spun and hammered to reset the wheel and spinner and it's in the same place re: the sharpie markings.
Hope this helps.

If you think acceleration "tightens" the spinners, what would you suppose stepping on the brake pedal does? Loosen them? Nothing?
Radial play between the wheel and adaptor will allow the potential for the wheel to either loosen or tighten the spinner. Make sure they're tight or get them bushed up. I've measured drive pins on the adaptors at anywhere from .515 to .525 and I've measured enough of them to think there are quite a few adaptors out there that are either worn or manufactured undersize. If the wheels have ever been run loose, you'll wind up with oversize drive holes in the wheels.
The adaptors are stamped LH and RH. To be correct with the book, use accordingly. I've run mine backwards for three years just to be contrary. No problems and I don't use the pins.
There are some mis-guided individuals out there who will disagree with my statements.

Sorry for beating a dead horse.
I did look for a search function under user cp...is there one somewhere else?
Anyway, FWIW I did loose a wheel at about 35 MPH in my current configuration "off towards front" about 12 years ago. I had just taken over the care of the collection from my dad and do not know whether the spinner was simply not tight or it had more to do with the thread orientation sans pins.
Leaving the adapters as they were ( off towards front) and adding the safety pins, I've gone perhaps 8-10K miles with no problems.
I was just curious if there is a definitive answer out there.
Perhaps I should leave well enough alone....=)

Arrow Towards Front
According to the diagram below the spinners tighten to the rear of the car, so the off arrows should point toward the front. I can never remember which way the arrows are supposed to point so to me remembering that the spinner wings face toward the front of the car seems easier for some reason.
