I'm sure you're on your phone - or have some other excuse for typos - but a large percentage of members on this site follow your recommendations as if they had come from Jesus. You've got yours but don't intentionally (or otherwise) mislead others as they attempt to follow in your footsteps.

yes, i'm sorry it were typos for sure, i HATE tapatalk.
anyways, the things i mentioned i base off of tires looking square on a wheel and having enough sidewall. a 235/40 is decent and yeah its closer to the oem tire size, but i don't think people who go for fitment and go to a meatier tire really care about stock diameter, atleast thats what the assumption is.
i by no means try to be "a guru", just passing on knowledge i soaked up.
i also base what i know from my times with the STi.
for example it came stock with a 8.5" wheel, on it a 245/40 was square. (a 245/35 is too small a sidewall) then take the wrx which has a 7.5" wheel factory and runs a 235/45 which is square.
then bump to a 9.5" wheel and a 265/35 is square and depends on tire brand so is a 255/35.
obviously none of this is taking into account stock diameters but thats what this is for:

however i was just responding to the question of "what will fill out XX width wheel" so a 225-245 (depending on brand) is good for an 8" and a 255-275 (depending on brand) is good for 9-10"... and so on and so forth. then throw in different brands and etc etc.
hope this clears any mix-up up. just my train of thought here...
