I’ve only put 6k miles on my new set of General Grabber ATX’s. Thus far, very happy. On my half ton I had, I put General Grabber AT2’s on and they were spectacular. The AT2 was the predecessor to the current ATX.
Thats my experience with Kuhmo's. Roughest, noisiest, slickest tires I ever had and didn't even make it 25k miles. Came OEM with the vehicle...My 2019 Ram 2500 came with Firestone Transforce tires. WORST tire EVER! I got just over 17k on them and were bald. Crappy traction the whole time. I put a 3" lift and 35" Toyo open country RT's and have been happy. I have about 29k on them now and expect to get around 45k.
