Thanks for the comments! As mentioned I built the model almost 30 years ago, so I don't really remember. I can only say that I use almost exclusively Humbrol metallics for decades. Therefore it is very likely that I used a mixture of Humbrol enamels here too. My tutorial about making wire wheels can be found here: Making real wire wheels in all scales http://www.modelcarsmag.com/forums/index.php?showtopic=77554 Reducing the width of the wide Italeri tyres is possible because they are massive, i. e. they are not hollow, and not too flexible. After slipping a tyre onto a fitting piece of tube I remove an appropriate radial section by cutting with a sharp #11 blade down to the tube in two longitudinal grooves. I discard the removed section and glue the remaining tyre halves together. After working carefully the glue seam is hidden in a groove. If you remove the radial section off-center the glue seam is off-center too. I mount the tire with the glue seam on the inside in order to hide it deep in the wheel well.
