I have had a set of these tires on a full size truck for the last 80k miles. They have performed very well on the street and good on the fire roads and light snow. I recommend them for a 4x4 that is used for general purpose . As far as something aggressive I could not be sure. Hope this helps.

I bought these not for off road (although I'm glad to have that option)... I bought them as a snow tire and they are AWESOME. Drove from Vermont to Syracuse, NY in an ICE storm, straight through the Adirondacks and never slipped once. I live outside NYC but spend a lot of time in Vermont and haven't used 4 wheel drive up there yet and you know what this winter has been like. My Suburban used to be AWFUL in snow, now it is a beast. You can not make these tires slip slide or fail in any way. Highly recommend. Thanks BF Goodrich!

I bought mine March of 2019 and put them on my 2018 Ram 2500 diesel. I have almost 15,000 miles, all road miles, and they already need to be replaced. I have not towed or hauled anything heavy, have zero off road miles and had only one extended road trip from California to Idaho. I have rotated the tires every 5,000 miles. The wear is even and I have not had any issues I can think of that would have made them wear so quickly and the tires have not been abused. Other than tread life, I have not had any issues with the tires.

I have had three sets of these tires. I love them. I have had them on a 89 Jimmy, 05 Silverado, and 02 Land Cruiser. I drive them hard and have never had issues. If I get a nail I plug it and keep driving. Every vehicle I put them on I sell before I need new tires. I rode them very hard in Africa and had zero issues.

I put a set of K02 37X12.50R17 124R D tires on my Jeep JKU and have used them for almost 6 months now and am thrilled with their performance both on the road and on the rocks in Moab. I drove from Houston Texas to Moab Utah for some crawling and the first thing I noticed was just how quiet they are on the highway! I was expecting them to be loud but not at all. I don’t do any mudding but I did drive down LaSalle Pass in late October and the trail was wet and partly snow covered. A week later I was driving up Goose Creek Trail #65 up to Goose Creek in the Carson National Forest and this time the trail was wetter up to about 9,500’ elevation where it turned to snow. We continued on no problem, with the exception of one thick ice patch which was no big deal but the higher I climbed it started snowing. By the time I got to 10,500’ I was in a full on blizzard and the trail was becoming difficult to see. The tires never slipped once besides that one patch of ice but not being prepared for cold weather thought it prudent to turn back. I don’t have experience with another tire so can’t compare performance but I’m happy with how these tires have performed so far.

I bought a used set of 31 10.50 15 with minimal tread for my old 85 ranger mountain ride I have a long steep driveway no matter the amount of snow and ice I can crawl up my driveway no slip couldn't imagine what a new set would pull like highly recommend if u have the cash. Lol

Definitely haven't driven it enough yet, or long trip to really get in depth, but so far, they are great! The appearance is way better than the stock tires that finally wore out and the ride so far has been very good. I anticipate the tires with a much knobbier gripping texture will be hugely beneficial in rain and snow.

I had a set of KO's and ran them what seams like 100,000K. Liked them so much i bought this set of KO2's because the KO was unavailable. I have had these tires balanced about 10 times. They will shake the heck out of you, like having an aggressive mud grip with a rim half full of mud. The "improvements" ruined what was a good tire.

Really dissapointed, ive driven about 7000 miles the tyres are very noisy, and have worn out of shape. The back of each tread has worn more than the front, especially on my front tyres. I swapped them front to back to find that i had no grip, it woukd go sideways around every corner!

I'm on my third set of these. I absolutely love them. My truck was t-boned yesterday at 40mph. My tire took some damage but I was still able to get my family home safe. Thank you for making such a great tire. I also spend a lot of time in the mountains and high desert. I've never had an issue.
