Also, on my 4Runner with factory 31" (well, 265/70-16) tires, the door tag still indicates 225 tires, and I have yet to see one that says 31" (or 265...) on it. If I decode the axle codes from the sticker, it does indicate I have 4.10's (but I knew that since I bought it new and still have the window sticker).

So, the only way to know for sure is to count...

All the ones that I come across with the factory 31's also still list 225's, the only thing different on the door tag is the gear code being G25? instead of G29? for 4.10's.
