I have a 59 gmc 2 ton. It has 20" rims and I cant figure out which type of rims it has. Ive looked in the tech tips and read Griggs post about different rims but I cant determine what these are. None of the rims in the tech tips appear to have this two inch ring aroud the outer part of the rim. Here are pics of the front, rear and the inside of the front rim. I dont have any pics of the rims with the tires dismounted. I havent touched the wheels since I got the truck (two weeks ago) in fear of not knowing what rims these are and how dangerous these rims can be. I know that the rh5's are the widow makers and are dangerous but what about other types. Specifically
these. Thanks
