I guess I'll answer my own question here too, since no one answered. There's apparently nothing presently available that matches, in the original sizes. The vendor I asked suggested Falkens, with a slightly smaller rear tire.
I decided to go with Coopers, not quite matching, but in the original sizes. Cobras in back mounted with the white letters facing in so they basically don't show. Not perfect, but hey, it's two years too soon for hoverflight.

What is available that matches front and back?
Or what does anyone suggest, period?
My Yokos are overdue to be replaced.
