The cheap caps on them did say ULTRA but I wasn't sure if that meant old or new.Those appear to be ultra wheels
Back in the day they were called radir's or raider's by M/T I can't remember,but now they are reproduced by Rocket wheels,Hurst also marketed a similar looking wheel but the spoke portion was gold colored,the hurst wheels were an aluminum spider riveted to a chrome steel rim,the M/T's may have been too that was pretty common back then,I do know they are some cool looking wheels.Ralph has Radar wheels on his 63.....View attachment 79312 by Mickey ThompsonView attachment 79313
