WW2 GMC 20" 6-stud wheel details

[Phil Waterman]

Hi Matt

Have you check this website cckw.org some of the people are extremely knowledgable on CCKWs and relater trucks and maybe able to help.

Also their forum http://cckw.org/forum/viewforum.php?...628b37d5eef32b

Cheers Phil

The pitch diameter of the CCKW wheel stud pattern is 8-3/4"
This is the same as Chev G506 1-1/2 ton (Yankee Joe), DUKW, White Scout Car and M series trucks with 6 stud wheels.
I would be surprised if IH used the same pattern. They tended to do their own thing to a large extent though I'm fairly sure the M-2-4 used the same 16" wheels as the Dodge 3/4 ton WC so you may be lucky.

What width 18 inch tyres do you require.
I have been looking into this problem for a Wiles cooker.
A Korean tyre company can supply 7.50 x 18 tyres new in Australia with a road type pattern.
If you are interested give me a PM
