Code 88 wheels would work as fine in S scale as they do in HO scale and P64
wheels would work as fine in S scale as P87 and P48 wheels do in HO and O
scales. It's not a matter of physics it's a matter of availability and pricing.
If P64 trucks were as easy to get and cost the same as SHS trucks I'd have
standardized on them long ago.
N scalers have proved that small flanges are just as reliable as big flanges so
use the wheels that appeal to you and don't worry about the physics as they
work.....DaveBranum
