Can't really answer your question. But I have Michelin 265/70/17 on mine

If meaning taller I would say 265/70/19.5.

take a look at my pics in my gallery. i have 285/70/17 and they do not rub one bit, very very close to rubbing but never had one problem with them. can tow a very heaviely loaded trailer and still wont rub. go any bigger, and your going to need some spacers.

If you wanted 16 inch info, I could help. Sorry. No help here. I'm a 16 inch man. I'm and glad however that i don't have to buy 17 inch tires!!!!

From what i was told 285-70-17 are the biggest we dually guys can go due to the width of the factory wheel. Im running that size, at first i didnt use a spacer but you have to watch tire pressure pretty close and that got old so I threw on some spacers. Hope that helps.
