I have run a lot of M&S tire over the years and the ones I like are the B.F. Goodrich All-Terrain T/A KO. I ran them on my 1995 Chevy ½ ton Z71 4x4. They were a big improvement over the Bridgestone’s I had been using. The Bridgestone’s were good for wear but did not have the traction qualities of the T/A KO. The first hunting season I had them one of my hunting partners had also installed them on his 4x4.
The test came when a good end of season snow storm hit during the night. The mornings hunt had us picking up an old narrow mining-logging road that had not seen maintenance in many years. The road has many large rocks and deep mud holes. Steep grades are the norm on the road. When we turned off pavement to the road we dropped from about 5000 foot elevation to 4300 foot, and then climbed to 6700 foot elevation on the far side. At the upper elevation I was pushing about 24-inches of snow. There was not lost of traction. The 4x and the locking rearend did the job. A couple of places I encounter large frozen over pools which were above the bottom of the doors. The rig kept on going. This was the test of the tires and they passed with flying colors. Most people stop at the first creek crossing.
The tires saved the day a couple weeks later in a different Zone. I was back on a steep unimproved dirt track and had dropped downhill a couple of miles. I made a long hunt on foot, and an intense rain moved in. It was just about an hour before dark when I made it back to the rig. I put the rig in 4H and the 4-wheel light did not come on, I put it in 4L and the light did not come on. I was concerned that I might have to hike a few miles out to the highway.
The T/A KO tires along with the locking rearend got me out of there. I should note that I do carry two sets of tire chains with me during hunting season, but they were not needed. The electric solenoid that shifts the front axle failed.

I looked at a few other lower price tires but I bought the T/A KO tires for my rig. One of the big selling points was the guy who bought my 95 from me. Two to three times a week he drove that rig across the Sierra’s to work in NV. He never had to chain-up when chains were required the tires wore like iron.
The tires on my rig are 31.8 inches diameter. A good chart for finding your tire diameter.
