So did the 10-lug pattern die in '56 (with '55 being the last year for it?) So all 1.5 and 2-tons were 6 studs on 8-3/4" circle, stud centered Budd wheels, after that? Until when?
No, the 10 lugs on 7.25" did not die in 56, appears as they were used until about 59.
Then revived in the late 70's or early 80's and used till 2005.
