I have 2007 lbz duramax so it's the classic body style. I have the torsion bars cranked 5 turns. Not quite level still has some rake to it. I currently have h2 wheels and 285/70r17 hankook dynapro atm tires. They rubbed the front bumper valence so I trimmed it a little. My wife got me fuel mavericks 18x9 +20 offset and 5.75 backspace. I don't wanna have tires that rub so anybody got recommendations on what size I can fit?

285/65-18. Tires are a lot more expensive than the size you run now. They make 285/60 but options are limited, I ran that size and they rubbed but my wheels were -20 not +20.

I'm not positive but +20 offset should be close to what the H2's are.

The +20 offset is a stock offset for our trucks.

The +20 on the OBS won't even be level with the fender flares and if you run a 12.50 in any size IF you're leveled, they will rub the sway bar and the UCA, it barely rubs but you can feel it and see it.

I ran a -12 on my LLY and they were perfect IMO.
I started out with a +20 on my LMM and sold them for a -12 offset.

I'm running 275/65r18 with no rubbing anywhere. Front axle shafts flat with 3" rear drop shackles.
