M series 2-1/2 ton trucks run on 9.00-20s and the wheels will fit straight onto your CCKW as they have the same 6 stud pattern.
In the US you should be able to pick up a set of these wheels at a reasonable price without too much trouble.
I have a set on my G506 1-1/2 ton Chev and the only problem I have is that at full lock the front wheels (tyres) contact the suspension.
M105 trailers also used the same wheels and 9.00-20 tyres.

Motto, M-35 , M211 900/20 (1950-up) rims are 8 in. wide compared to CCKW , G-506 6 in. wide , the 6 stud pattern is the same ,The problem is the inside rear wheels hit the springs ( because of the 2in. off set on the newer rims and larger tires) when mounted on a CCKW ,( At least with my split axles ) not sure about banjo . I think I've found the answer to my problem is to use DUKW spacers . DUKWs ran spacers on the rears to mount the 18 in. rims and have clearance for the brake drums , they are about an inch and a half thick and bolt right on.

Oops, because they fitted on the G506 Chevy (only just on the rear due to the hand brake cable which the CCKW doesn't have) I had assumed they would also fit the Jimmy.
I have DUKW adaptors here but didn't need to use them on the Chevy. Also they would make the tyres stick out past the rear mud guards (fenders). I am going to put White M3A1 Scout Car wheels on the front as they were made to take 8.25-20s and the offset should be about right. I will be putting 9.00-20s tyres on them same as on the rear.
Originally, the DUKW spacers were held on with tube nuts as used on the inner duals of G508 and 506 trucks. These required that the wheels have 12 holes in them instead of just the 6 needed to hold them on. Have you got around this problem?

Thank you Motto ! I was wondering how they where mounted ,the nut that fits is to big (it fills the hole ) theres no room for a socket , I was thinking a bulge nut or convex,flat washer and 1in/1/8 nut and lock washer. The reason I'm doing this ( I know the tires are to big and don't look right ) is that I like to drive this beautiful , beautiful truck every day that I can , I have a 1936 4dr Plymouth all stock that I drive a lot too , I think people need to see these rigs running around , lots of people remember lots wonder what they are . I don't have a lot of money , I'm doing running restoe's on my rigs ,so far I've got 4 new 750/20s NDTs ,I'd rather run 900/20s until I get my stock rims and tires together ,( and then save them for show and meets ) I can't wait to get my 1970 W300 power wagon running (real close ) my CCKWs the cream of the crop ,best rig ever in my opinion ,I haven't driven 50,000 miles in it yet but I'm headed there ( open cab at that) . sorry for going on , If you know of washer or nut or something that might work please let me know ,Thank you. Do you have a CCKW ,do you have G506 ?

I have two CCKWs at present, both unrestored. One is a long wheelbase, winch model, open cab, banjo diff truck that came from Israel partially dismantled and the other is a short wheelbase, open cab, banjo diff truck that started its life as a hard cab long wheelbase model. I shortened it up as the chassis had been broken and poorly repaired and I had acquired a SWB cargo bed and spare wheel/fuel tank set-up.
I also have a G506 1-1/2 ton Chevy 4x4 that originally carried an earth borer. I purchased that from a fellow in New Mexico about 18 months ago.

In regards to the DUKW wheel spacers, I don't know what to advise other than what a friend did with a set one time. He wanted to put 12.00 - 20s on a split diff truck and one of his problems was that the studs on the spacers are to accommodate singles not duals. From memory he removed the original studs and had replacements made from steel bar that he secured with a nut on the inside and the outside of the spacer. The nuts on the outside were thick enough to allow for the standard spacer retention with tube nuts and large enough across the flats to give a decent surface to pull the inner dual up against. He didn't finish the truck so we never found out how it all would have worked in practice.
