The GMC CCKW

Will an 11.00 X 20 tire fit on a CCKW rim? My friend found some tires on rims he was told came from "WWII Deuce and a Half." But the tires have 11.00 X 20 tires on them. What is the outside bead ring to bead ring measurement on a 7.50 X 20?

In 2 letters; NO

I bought some 8.25 mud and snows for my 42 chev plow truck and could not get them onto the rims. I finally got some M35 rims and they fit fine.

Thanks. These rims turned out to be dated in the 50's and the shape of the locking ring was pretty different. I am pretty sure they are M135 wheels and tires.
