Think I'm gonna go with a 20mm offset

 

Sorry, I misread this statement. I had a dyslexic moment slaughter it.

What I comprehended and therefore replied to was "so im def running a 2in leveling kit with this tire on a 15mm offset rim?" - thinking you were contemplating leveling it or not. Not what you were saying obviously.

Sorry, been lacking in the sleep department lately. I dont know how well that tire will fit. I am confident it WILL rub. I'm not exactly sure what exactly you will need to do to make it work. My tires are 33.2" tall (305/55R20) on a 20x9 wheel with an offset of et20. (Wheel size does not matter, only tire width, wheel offset and overall diameter.) Mine rubbed slightly when new... on the flares where I mentioned before. The tire is also pretty close the the front wheel well liner on the cab side at certain turn angles.

 

Yea no I've got my truck leveled already just going for tires n rim now
