6x5.5 or 6x139.7 ???

Looking for a set of 20"s to fit my old girl but the fitment guides I have found are a little confused!
Is it possible that different countries have different fitments? (I very much doubt it!)
Some guides show that Isuzu,Toyota and Mitsubishi run the same pattern but others say the mazda has a fitment all of its own .
And don't get me started on offset!!!


Do we have a definitive list of matching fitment vehicles on the site somewhere?

6x5.5 fits chevy and pretty much every other 6 bolt japenese truck/suv

gotta be careful about center bores as well! i think the nissans are smaller than ours.

6x5.5 and 6x139.7 are the same bolt pattern technically but center bores is where it'll get you

been curious about this myself though i'm only looking to put sixteens at the max
