[TR] Wire Wheels

[pethier at comcast.net]

I spoke (no pun intended) directly with an engineer at Dayton. B 
Chromed-steel spokes are no good do to hydrogen embrittlement.
Stainless spokes are strong, but the threads are not strong enough to allow
serious tightening.
The best bet for serous driving is painted steel. B Dayton uses high-strength
wire with robust threads and tightens the wires enough that the wheels are
very rigid. B The wheels should never need to be trued.

Best wheels for spirited driving are alloys. B If you must have wire wheels,
go with Dayton painted wheels. B Strong, original in appearance, and cheaper
than the chrome/stainless ones.
