TLDR: 4mm offset, no wider than 8" rim, without super aggressive square shouldered AT tires is your safest bet. note I said safest, not minimum
this is a difficult question to get a straight answer on. If you do an internet search you will find a lot of conflicting experiences about similar set ups rubbing and not rubbing, especially those that want to swap for the TRD pro rims which I'll use as a reference point
I went down this rabbit hole because I am considering replacing my 20" rims with some 17". basically here's what I found out. I hope it helps someone out there
- if you are running 265s on stock sr5 or trail rims, you will likely not have any issues as the offset of 15mm is the same between all trims EXCEPT trd pro
- trd pro offset is 4mm and I believe 7.5" wide. if you are swapping to a trd pro rim you MAY have issues if you select an aggressive AT tire and an AT tire brand that is known to run larger (falkens for example). AT tires generally have more squared shoulder profiles and wider tread widths (different from tire widths) than say michelin defenders. I say MAY because some have issues, some dont. If you are planning on running falkens or even nitto on a 4mm offset or less rim there is non zero probability that you may have some rub. tire sizes are nominal and vary slightly between manufacturers. I've seen someone run TRD pro rims with toyo open country ATIII and have no issues, another run TRD pro rims with falkens and have issues both on 2014+ trim levels. the rub would be minimal and a heat gun can solve this
- based on my above point, I'd say a 4mm offset is the lowest you'd want to go with at most an 8" wide rim
- if you have an older model limited 2010 - 2013 before the facelift, you likely will not have issues with a TRD rim and aggressive AT tire. it seems to be the newer models that have the rubbing issues with the TRD pro rims
- note the newer model TRD pros have fender liners modified at the port so the TRD pros with grapplers fit and don't rub
