Thomas, I'm not sure of the full answer to your question, but the
following might have something to do with it. I have a couple of sets of
wheels. One set is Dunlop, they are 14" painted spoke wheels. I also
have a set of 15" Dayton chrome (SS) wire wheels. My hubs are in good
shape (the rears have less than 1000 miles on them), the fronts have more
miles but are in good shape. One of the Dunlops is brand new, all of the
Daytons are new. I "tested" the play on all the hubs with the new Dunlop
vs the new Dayton. Guess what? The Dayton is a much better fit. In
fact there is no measurable play. The Dunlop on the other hand has about
1/8th inch of play measured at the circumference of the tire. Larry's
theorem of spline wear: Where there is movement there is wear.
I think where we get into trouble is when we buy a new wheel and put it
on an old hub or the other way around. If either of the components is
worn it will accelerate the wear of the other. In the case of my new
Dunlop and new hub they had slop to begin with.
One other thing, in my opinion I don't think you can get your knockoffs
too tight (see Larry's theorem). This has been a bit controversial, I'm
sure someone else will put in their 2 cents worth on this one.
Cheers,
.
