Apparently down in Melbourne hobby stores they have plenty and they're only around $20-$22pr, so I've been told.
For the next worlds they are looking at controlled rims and inserts and pre-mounted tires.

proline touring tyres are always the biggest pain to mount.. and to try and get them true..
The proline K's I've found work very well on Yokomo inch up rims with HPI red inserts. They also fit perfect and are no troubles gluing or making sure there round. But this is just what I've found. You're definitely right about the wear thou, pity they're not belted.
