This may sound ridiculous but I need help to determine whether the rims I have are 17” or 17.5”. I’m about to order tires for my ‘58 3/4 ton Napco project and I don’t want to order the wrong size. I posted pics below of measurements. Overall rim width is 7” and overall diameter is 18.5”. I don’t see markings anywhere on the rim that would indicate size. Didn’t Napco trucks come optional with 17”, 17.5” or 19.5” rims? It’s a 3/4 ton 1958. Any help would be appreciated. Thanks.

Rims are almost always stamped on the outside(green) next to the outside (green) opposite of where the bead seats. Yours look to be 17" rims.

Many rims have been stamped on the inside, near the valve stem hole. Sometimes it's hard to see, you may need to sand blast the rim to see it...
