To answer your question, that size would work very well on a 2.5" leveled truck with stock wheels.

I am reading it will and I am reading it won't. Someone gas to actually have it on their truck and knows for a fact LOL.

The 275/70/18 duratracs are an option too

I am telling you that it will work. I ran 295/55/20s which is damn near the same height and is wider on my 2" RC bottom spacer'd 09 Sierra and it wasn't trimmed at all. You might rub at full lock on the sway bar, but you will be fine otherwise.

And here you go, 2.5" CCM with 295/65/18 DuraTracs:

Planning on running 305/55/20 on an RCX 2.5 leveling kit. I have 3 wheels in mind:

20x9, -12 offset, 4.5 backspace
20x10, -12 offset, 5.0 backspace
20x10, -24 offset, 4.5 backspace

I have no preference for rim width, I just want the setup that will poke the most. Will the 20x10, -24 offset require the Nor-Cal Nick mod?

Yes I did x10s -25 and had to do the fender mod and I have 305/50s

Will I need to trim in order to run 305/50R20's on a NNBS with a 2.5" TGC level kit? Rims I want are 20x9 with a +1 offset.
