Hey Rustednuts,

I like the wheel that you have pictured.

Can you or anyone tell me what production year the wheel pictured started, and then when was it produced to what year? It looks like you have the 5/8 stud hole as well. Not 9/16.
As a note, the 1941,42-46 First Design utility had a change when the Second design was introduced in the PK series by enlarging the lug stud from 9/16 to 5/8.

I have a 1941 utility parts truck (YS) that has 6 of them, and I am hemming and hawing as to keep them or go with the standard wheel. If I use them, I am almost positive I will need to oversize the hole to fit the studs. I do see them in the 1942 Special Equipment (Silver Book) for Chevrolet trucks. They are mounted on a what looks like the 132-5/8 inch wheelbase 2-ton COE pictured with the heavy duty model Holmes Power Wrecker.

I see you have 7.50 x 20 on it now. Is the offset of these capable for running 8.25 x 20 tires with no interference on the 160 inch PK series wheelbase utility?

What do you call this type of wheel? Is there a name to these? Like a heavy duty artillery wheel? Or 8 spoke or 8 hole? I assume they are native Chevrolet, GMC?
I have now seen about five or six 1941-46 Chevrolet utility’s with these special wheels. As always, thank you for your assistance.
