[TR] TR2/3 wire wheel adapters - frightening experience.

[David Greed]

Surely the LH threads should be on the LH side and RH threads on the RH side – that’s how it is on any vehicle I have dealt with…

Randall,

 

That being the case, then why are wire wheel nuts R/H thread on the left side and L/H thread on the right side of the car? Not trying to be a smart ass, just puzzled.   Wire wheel nuts are self tightening, aren't they?

 

What's the difference?

Loctite would be a good idea here.

I'm not sure about Loctite, but it is definitely important to torque those
funky double-taper nuts to 65 ft-lb (not the 50 ft-lb used for regular lug
nuts). Not just any time you have them off, but every year as part of your
annual wire wheel maintenance (IMO).

The physics is a bit hard to explain, but basically because they are right
hand threads on the left hand side; any tiny bit of motion will eventually
unscrew the nut!

I had the same thing happen with Dad's TR3A many decades ago, except I was
fortunate enough to notice the squirrely handling caused by the adapter
being almost off the studs before the wheel actually parted company. Just
pure luck that two of the nuts were still on the threads when I took an exit
ramp rather faster than I should have.

Then the same thing happened again, same car, just a few years ago. That
time the wheel did come off, taking the fender with it.
