Max Tire Size on Stock Dually!

Ok, I know this subject has been beat to death prolly, but I havent got an answer from any of the threads I looked at. I'm fixin to get some tires put on in the next week or so and was curious what would be the MAX size I could go on my truck with or with out a 2" leveling kit? I'm hooked on the toyo open country mt's., would 285/70/17 fit without spacers or no? I'm clueless when it comes to tires sizes!! Any help would be appreciated guys!!

255/80/17 is the biggest you can run without spacers between the duals. If you wanna run 285's you will have to run at least a 1.5" spacer between them.

EDIT: Toyo does make a 255/85/16, not sure if they make a 255/80/17 or not. Its basically a skinny 33" tall tire. I know BFG makes the KM2 in the 255/80/17

So I could run the 285's with a 2" spacer? Is that with a leveling kit also? I don't mean to ask so many questions but I wanna do this right the first go around! Lets say I put 2" spacers on, I could fit what 285/70, 285/75??? Like I said I'm CLUELESS when it comes to tire sizes!!

You do not need a leveling kit to run 285's & a 2" spacer would be plenty of room for 285's. when my truck was a dually i ran 285's with a 2" spacer out back & there was plenty of room between the tires.

Dang - I was going to try a 265/70R/17 on mine with no spacers. It'll rub, eh?

i don't think so, i've seen 265/70/17's run without a spacer, i'm not saying all tires will fit without a spacer (all brands are a tad different) but i have seen several trucks running that size in stock form.

I really dont think i NEED 285's that was just the tire i was kinda lookin at. How tall are the 265/70's? I use my truck for my job on the pipeline and when it rains, you HAVE to have a mud terrain tire to get around. I was just needing something to lift me up just a little bit and give me some good grip!

I like those 315's.....you got a leveling kit on it? I've heard that if you have spacers it takes away from the towing capabilities?! Not sure on that but thats what I've heard so therefore I want to avoid spacers if its true. I pull my 36' fifth wheel from job to job and still need to be able to pull it and not worry about it.
