I'm not sure that percentage of expansion is the relevant consideration
here. I would think that the gap between the cylinders (i.e., portion
of the diameter) is the important part, and since the expansion occurs
in the circumference the gap changes by a factor of pi less.
Even less reason to be concerned, I think.

Circumference and diameter grow by the same percentage (since C = d *
pi), so CTE wise, it's the same whether you use diameter or
circumference.
