best offset for 17x7.5 wheels on my 86 ranger

i've looked around on the forums,and not found my answer yet.whats the best offset for my ranger with 17's so they'll tuck?i'm running i-beams on the front, so i'm not sure if that makes a big difference.and are all rangers fitting those standards all the same as far as offset?thanks for any advice.

bodydropped you will need atleast a 5.5 to tuck.
