Stock tire size is 33''. The offset and width could case a bit of rubbing but I don't think it'll be extreme.
If you need to level, I went with a motofab 2.5'' top spacer on mine. It was painless enough to install and inexpensive (70$). But you could easily get a set struts for about 300$ that should level the truck out a little up front to give you more clearance.
Take pictures and update when it's done. The wheel and tire combo will be nice.
