I am wondering more about potential tire noise with that tire size. do you notice more tire wear in the center of the tread?
First of all, more tire wear in the center of the tread is indicative of low air pressure and or a mismatch between tire and wheel sizing.
I have run 2 sets of KO2s in two different sizes on my trucks but not your size. They did get noisier as they aged and were so loud towards the end of life that I thought my front differential was going out. Noise in my Yukon XL was not objectionable when they were new. Curiously, the other set installed on my pickup was louder from day one.
The tires are fantastic off-road, mud, beach sand, sugar sand, dirt, etc. They are fantastic in the rain too. They picked up and moved a lot of rocks and dirt, but shed the rocks and dirt from the treads really well. They picked up road hazards too. My touch up paint pen was kept pretty busy until I put splash shields on both trucks. I got into some pretty hairy situations off-road and they never left me stranded.
About once a year the Load Range C tires were punctured and required patching. It was always a slow enough leak to not require a tire change. Then the pickup with Load Range E tires picked up a bigger nail that broke a belt and destroyed the tire. That's when I sold the remaining three and put Defenders on it.
Replaced both sets with Michelin Defenders. Sure, they don't look near as nice but they are quiet, even better in the rain and have gone just about everywhere we went with the KO2s off road and didn't get stuck. On top of that, knock on wood, no road hazards either. Mileage wise, the KO2s will last about 50-60K miles, the Defenders 80-100K miles. Down here in Florida, they all rot out from the sun's UV rays in about 4 years.
We also saved a ton of rotational weight going back to a P-Metric tire that weighs about 38 pounds versus the 48 and 54 pound KO2s. Each pound of rotational weight is like adding 8.4 pounds to your payload. We proved this by our runs at the drag strip with the truck. The truck picked up about 4 mph in the quarter mile and our times to 60 feet dropped .4 tenths of a second on average as well.
Of course, coasting improved, off the line performance improved and gas mileage improved.
KO2s are great tires and when I bought my first set in 2017, they were king of the hill. If you are set on getting them, go for it. Just realize what you are giving up for looks and off-roady performance.
One last word of caution, if your new wheels extend the tires and wheels out past the fenders, keep a couple of paint pens handy for all the rock chips.
