Kato locomotive wheel sizes

[Chris333]

On one of my HOn30 locomotives I used Kato diesel wheelsets. Their diameter is 7.35mm that comes out to about 46.4" in N scale. What locomotive has wheels that big?  Just trying to buy more and have no idea which ones they are.

Is it the sd80/90macs? Without looking them up or measuring the one I have they have pretty big wheels.

Well if I knew...   and it doesn't help that those wheels have no photo at their site:

I can confirm that the SD90/43MAC has 7.35 mm wheels.  I doubt you would be happy with the wide-tread wheels you linked to, but the narrow tread wheels don't seem to be available separately at the moment*.  You could order the full truck and scavenge the wheels:

*Since they recently released a new run of the SD90/43MAC, they may restock the newer wheels soon.

The wheels I have are a little chunky for N scale, but just right for HOn30    I'll order some, Thanks.
