Hi,
i made the tyers the old fashion way.
I used a stationary grinding machine and a circle for the diameter.
I made a half tyre and a mould for the resin.You can see it on page 5 i think?
The rims are made from different tamiya rims.
The front rim is from the porsche 934,but with resin slicks from me.
The rear rims are parts from the porsche 935 with the bbs inlet from the porsche 934.
