On a kelsey hayes 14 x 5.5 steel wheel with a k2 9 underneath does the 9 mean 69 or 79? It's smooth dome 4 nub 5 lug with 1 extra hole between 2 lug holes, maybe originally white. The k2 9 is on the band inside where the tire is mounted with nothing by the valve stem. It was in my 70 charger Road wheel car but who knows if it was original. Thanks just wanting to educate myself.
