Found a way making the tires. Material used is hi dense styrofoam. After sanding with 400 grit sandpaper the texture is spot on. It will have to be painted and for that I'm using PVA glue and water based paint mixture. PVA also protects the soft styrofoam surface from scratches.
Front left wheel is done and rear left is one step behind. Materials used: gray primer, gloss black, polished aluminum and aqua gloss clear. All above from Alclad2.
