First I apologize for the errors and incorrect questions I posted above , ie asking about a wheel when I meant tire or posting erroneous data. In removing the tire-less insulator from the axle I broke the insulator - see photo 2 - never had that happen before. I decided to pursue the following:
Using an old freight car wheel set with insulators on both wheels(see photo 1) remove one wheel and insulator, chuck axle in a Dremel(or equiv) and using a micro-file, on remaining wheel turn tread dia. down to 5 mm and flange dia. to 6 mm.
If the turned down wheel doesn't have a shoulder on the insulator as shown by red arrow in photo2(original pilot axle) or photo3(Minitrix freight car wheel set) use an insulating washer( similar to one furnished with M/T trucks as a spacer) to keep wheel from shorting out to pilot frame.
Photo4 shows completed wheel(rear wheel on pilot). Locomotive runs fine in opposite direction to throttle and tries to pole vault every turnout and crossover it encounters.
I think I'll set it out front of my round house and work on +- 2ft lateral movement  on my schnabel car - how many n-scale schnabels have that?

OK, seeing this apart like this, this is a pretty straightforward lathe job. 8)  Send me the whole pilot assembly and I'll make new hubs in black Delrin with all necessary features including machined extended insulator to prevent shorting, reassemble in gauge, and return.  If you want the flanges reduced I'll do that too. 8)  Send a PM if you'd like to pursue this.  :)

Al-
For what its worth I looked through my parts bins and didn't come up with anything.
I used to have a complete lead truck and a couple of other JAMCO parts but must have sold them off with the Atlas Rivarossi 4-6-2 and 2-8-2 spares.
I recall the lead trucks as being a turned plastic or nylon without any metal tire on them....but it has been over ten years since I laid eyes on them so my memory might be faulty.
I've been looking for a photo I had of the Pilot Model for the Jamco Pacific....it was every bit as nice as any HO import from Japan or Korea.  I will post it if I run across it again.   It was completely fabricated out of sheet brass with only lost wax castings used for detail parts.   The builder decided that was too much work and delivered the version you have without telling the importer.  He had no luck, as his next venture was a replacement Milwaukee Hiawatha F7 Baltic 4-6-4...and I think he used the guy that was caught smuggling brass across the US Canadian border at Detroit and only a few samples made it into the country.   They were pretty crude but "back in the day" could have been the start of a nice business as N Scalers were very hungry for a little variety!!

Just as a reminder, we have Randy's recent thread about this exact loco : https://www.therailwire.net/forum/index.php?topic=46241.0

Here is Randy's photo of the model I borrowed from that thread.  It shows the pilot wheels with metal tires (not all-plastic).
