Rotomo /special tyres...Sandblast,then smooth on lathe or lay flat and use a small orbital sander to smooth the walls.Lathe to groove,you can do it plenty of ways count the grooves and make a castleated tool with depth stop or use a single tool with a point like a screw driver and make sure it is depth marked.re clean then you can paint or tyre shine....For later wheels cover the centres,sandblast tyres if you want...or clean them in sugar soap solution i find best instead of petroleum based degreasers..or you can use an alkaline. regrooove on lathe,with the tool you made.....or by hand....or you can make a sleeve for your bench grinder 1/2 inch centre 2 large flat washers and do them on this. BUT do VC wheels have cross tread? if this is the case then your in for some seriously tedious and accurate grooving by hand ONE BY ONE.......GULPS.
