I found my space saver spare on ebay, its from a mustang. Bolt circle is the same, but the way the rim is made I dont think it will mount on my car properly, if at all. Ive never tried it, nor would I ever use it. Obviously....an ornament.
Also, pretty sure its the same actual tire and brand used in mopars, but the code on the tire is different. No one but purist nut judges will ever know.
I guess you could say my tribute has some ford dna in it, but its only along for the ride...in the trunk.
