Question about some SR5 15x7 wheels with different offsets
 

ok, this is just for curiosity sakes (but it is bothering me, so i thought i would ask):

i have a set of SR5, aluminum, 15x7 wheels on my 90 4Runner with an offset of 8. then, i have a identical looking spare SR5, aluminum, 15x7 wheel but with an offset of 15.

from what vehicle did the 15x7 with the offset of 15 come from? i know it fits my 4Runner.

thanks :D

I think they are from Land Cruiser 80.
