Wheel sizes for Athern passenger cars

What is the Wheel sizes for Athern corregated passenger cars?

I believe that they should be 36 inch scale diameter.

Do you have any way of measuring the diameter, such as a caliper or micrometer? A 36 inch scale diameter wheel should measure about 4.413 inch; a 33 inch scale wheel scale wheel should measure about 0.379 inch.

Wouldn’t you have to shim the heck outta the couplers if you put a 4" wheel on a car?? [swg]

No, that’s why Kadee makes the appropriate underset couplers!

Thanks. I meant 0.413 inch.

I just checked the stock wheels on some Athearn heavyweight cars, and they’re about .410", while those on an older car, with all-metal trucks, are a bit smaller at .400". While the trucks on the lightweight (corrugated) cars were different from those under the heavyweights, they all used the same-size wheels.
