unrepairable, you could try tyre plugs, which are much better, they work by pushing a big rubber plug into the spot where the puncture is and you just cut to size and it lasts the life of the tyre, you can check on how to do this by looking on youtube,
hopfully you wont need to do it!
good luck with the new wheels, exciting

I would only use the foam as a "get me home" then replace the tyre so not an issue really.
