well Mauro, that was the plan, I made this one by drilling out the inside of the tyre, and apparently the tyre is made of 2 different rubber, inside harder type, outside flexible rubberfilm
but it is very thin and I pierced it on a side, and the rubber was still to strong to "flatten " by itself, so I filled it with carbody filler and pressed it together until it hardened, then i put some more putty on the outside and smooth this out, but the joint between the rubber and the filler kept breaking, so I gave it a good coat of thin superglue, to harden the rubber , sanded a bit, then light coat of primer to see the defaults, and finally after some more sanding, I decided to put some more putty on , this time 2part putty like magic sculpt sort a thing,still need some fine tuning, but after that I think i will make a cast, then clean it up some more untill I find it real enough, then make another mould
so I can use them on another ural I've build
never made a copy, got the silicone, and resin, but I guess this will be the first attempt at "making my own
"
even if the "kit" tyres aren't accurate, I can alwways say I made'm myself
