Thanks for the answers friends, i deduce the correct tires sizes for my next project the Ligier JS 11 are: front 10-22-13 on 11 x 13 inches rim and rear 19-25-13 on 19 x 13 inches rim,the task is reconstructing new rims at the lathe and build up new tires in rtv rubber with the construction of special moulds male / female to make the casting.Of course the kit I'm working on that has tires problems is the Heller in 1 :12 scale.
