Norman, I see you ask this same question many times.

Perhaps if these are critical dimensions, you would do well to specify WHERE the tread diameter is measured.

Clearly not the smallest diameter, I often measure at the base of the fillet between the tread and flange, since I am concerned with trackwork, especially switches.

The best measurement is often at midpoint on the tread, i.e. somewhat of an average between the largest and smallest diameters.

I often wonder what “Norman” ever does with all the information he keeps seeking.

In some cases if he told us why he needs the information, it would possibly be easier for others to aid his quest, in an intelligent, and informed manner.
