I have a set of 4 huge billet aluminum wheels. They are 2" x 3.75" and I can't remember where they came from or the truck they were used on (it's been over 20 years and I'm sure I killed too many brain cells back in the 70's). If anyone has ever run across something like these, or would know how to find tires for them or have any idea what kinda truck could use them...would ya help me out?? I'm including a couple of pics.
Any feedback would help.
Thanks,
Michael
