GR3 tyres and wheels
I have some non-airworthy ones that may be suitable for you.
We had a brake fire a year or so ago and damaged a tire and wheel, plus we've got a tire that we just changed for tread wear. I know a recapper that could make them look cosmetically new. Whether he would take your word that they are NOT to be used for any flight is another story or he could drill a small hole in the tire no one would ever see.
We can trade for ???
