Tire Rack lists a couple.  A 145 for $52 and a 165 for $66...plus shipping.

Not sure what width rim and sidewall you need, though.  Hopefully someday I'll be searching for some 12"ers too....someday.

The 145 & 165 tires at TireRack.com may not actually fit.  The 145SR12 is the same as 145/80/12 which has a 21.13" rolling diameter.  The 165/70/12 has a 21.09" rolling diameter.  These may rub the rear swing-arm and/or outer swing-arm mount plate.

To find out, carefully measure the distance from the rear hub center to the trailing edge of the outer swing arm mount plate.  This distance needs to be slightly greater than 1/2 the total rolling diameter of the wheel/tire combo to avoid rubbing.  The plate edge can be ground down slightly to provide a very small amount of more clearance.  The other place to check for rubbing is where the curve of the swing-arm blends into the hinge-axis (the inner leading edge of the tire).

Sometimes the 165/70/12 will just fit and other times it rubs.

If you still need 12" rubber, try www.minimal-motoring.com usually in stock and pretty much unbeatable prices on tyres.
