So,
Just got the 34X10.5's mounted yesterday.
As mentioned, they are not earth shatteringly larger than the old stock M/T's.
But they are bigger.
I have them on pro comp 51 series steelies and there is no rubbing even at full articulation.
Only have a day on them but they are super smooth and quiet on the hwy.
Overall i think it was the best tire for my situation.
Thanks for the the help and input along the way.
Peace

We need pics! When my KM2'S wear out, I'll be looking at these. My KM2'S are 255/80/17's. I'm imagining the KO2'S in this size will be slightly wider. Their published diameter is almost identical.

I originally just got 4 ko2 34's and was using a new km2 255/80-17 as a spare both on stock rubi rims. They are so close to the same size it is not funny. the Km2 might have actually been a smidge taller but not enough to matter for a spare if I would have had to use it. The KM2's is more aggressive so visually look bigger if that makes sense. the ko2 is slightly wider but again very close to the naked eye.

They do appear to have about the same specs. Any chance you'd have time to put your spare on one front side and take measurements comparing it with the Ko2 on the other side so we could see the difference with weight on it?

LOL. probably not. I have since gotten another KO2 for the spare. I know tho from having them side by side off the jeep they would be within a rch of each other.
