I got these wheels on my 57. They are 15" 6 lug, and have a single screw holding the hub cap on. I'd like to know what these came off? Ive searched and have not found anything like these. Anyone know what they are off or the brand / year etc? I need new tires and am debating about keeping these or finding some used alternatives. These have 275/60/R15 on them. Hopefully the image attachment shows up for reference.
