Check out the pics in my album. 305/45/22 on OEM 22s. I wouldn't worry too much about the 9" wheel width. Also, not sure of the look you're going for but 305/40/22s don't have enough sidewall for these tucks. IMHO

I have 305/45/22 nittos mounted on OEM CK158s with stock ride height and have very little, if any, rubbing. You should be fine.

I agree that the difference in sidewall and OD is minimal, but I wanted a little something extra all around. I have 285/45/22s on my lowered Tahoe and love the way they look. However, these trucks have a completely different look than Tahoes, so I don't mind the extra bulge around the rim (I know exactly what you're talking about. I saw that size on a Tahoe and thought they looked like balloons). Very nice ride, by the way. I was debating between the CK158s and CK159s. You can't go wrong with either.

Here you go (FYI - I have no idea how to make the pictures show up as large images) I believe I've read that others are running 305/45/22s with a 2" level and had no rubbing. I looked last night and I don't see any signs of rubbing anywhere. There's no marks on the wheel liner or sway bar.

I posted this pic a couple of pages ago. Running 305/45/22 Terra Grapplers with no change to the suspension. Only slight rubbing in reverse at full-lock. Rides a bit stiffer than stock, but it's not terrible. The sidewall on the 285/45/22s was just a bit too short for my liking.

Just picked this bad boy up last week. Loving it.

Finally bought a new truck. 2015 Denali Immediately swapped the stock 20s for GM accessory 22s (CK158). Wrapped in Nitto Terra Grapplers 305/45/22. I've only noticed a slight rub at full lock in reverse. It rides a bit stiffer, but it's fine with me.
