My car have a 14 inch Honeycomb but in the trunk i find this and i think is one of the original because have correct code...
"M4" plant (where is this plant? i find M1 and M5 but nothing about M4)
"0" 1970
"8" August

Very strange but i think in Switzerland the original "Firestone" were being replaced by "Pirelli" before the car was sold...
