Tire size?

I’m sure this has been discussed a thousand times. I apologize in advance. I’m not having much luck finding past discussions about it. I have an 04 ccsb 2500 hd that’s leveled that I bought a set of 20x9 +18 wheels for. Obviously I need load range e tires. I’m leaning towards nitro terra grapplers. Which one of these sizes should I get: 265/60r20 = 32.52 x 10.71
285/55r20= 32.36 x 11.69
295/60r20= 33.94 x 11.77
305/55r20= 33.23 x 12.44

265s will look small on a leveled truck. I have 33x12.50 on mine with same spec on wheels and not fully leveled. Doesn’t really rub. Just trimmed the lower valence and had to heat the inner liner at the wiper reservoir. Any of the other sizes will be fine. 295s May rub a bit.

I run a 285/55R20 on my truck very slightly lowered on a 20x9 +0 wheel. They wear very well and have the slightest rub on the inner wheel liner just every once in a while. I think a 295/60 would fit well and look good on a leveled truck with a +18 offset. For what it's worth, I'm on my third set of Terra Grapplers in the size I stated earlier, and I have gotten 46-48k miles out of both sets. The second set was changed with a little life left in them because I had a sidewall puncture when I was almost to the point of changing them anyway. This new set is their new G2 version, and they seem to be wearing just as well as the first two.
