I took a chance on KO3s for my f350. With the improvements made for better wet traction, changes to the compound, and the fact that they are an OE option on GM trucks, I thought they might work well on the Super Duty. I have been back to discount tire twice for rebalancing, the second time being road force. One tire was at 79, the others in the low 30s. They took a decent amount of weight to balance too. The 79 tire was replaced, and the ride has improved but I don’t have a lot of confidence in them after this experience. I also have been disappointed with towing and on road performance compared to the stock Michelin LTX AT2. I am going to give it a few more days, but I have a feeling these are going back to DT in exchange for Toyo AT3s or the Michelin Defender LTX Platinum. I think they could be a great tire for someone (if you get ones that balance well), but maybe not for me.
