The worst tires I have ever put on my truck period. 15000 miles and tire tech says they are worn out. They will not stand behind warranty because I missed 1 rotation. DO NOT BUY THESE! Going back to duratracks.

Don’t buy KO2’s. They wear quickly. Started cupping early on. I rotate every 3k miles and service my vehicle regularly. Had suspension checked. No issues. I have a friend with the same issue.

Bummed the tires are almost impossible to balance. The technician had to use more weight to balance than normal, effecting appearance of my almost classic Jeep. Also, weight clips catch salt that corrodes my polished chrome wheels. Tires seem to handle conditions as advertised.

This things are dangerous. Experienced my third tire disintegration today. All have been at highway speed and today nearly caused a loss of control. The first, I gave the benefit of the doubt to the tire. It had been used hard off road and was on a heavily loaded truck. The other two have both been taken care of with minimal hard use in, thankfully, unloaded conditions when they failed.

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 full set less than a year ago. I’m on the highway a lot for work, so I’ve put a good deal of mileage on them. They started out great, but they went downhill fast. 2 of the tires had to be warrantied out at less than 25k miles. Two others are wearing unevenly, causing heavy vibrations. Keep in mind, I do a five tire rotation every 5k miles and don’t drive harsh or aggressively. They just don’t have any longevity, especially for the price you pay for them. A friend of mine also has ko2s and said his are doing the exact same thing. It really turns me off to any BF Goodrich product because it seems like their QC is garbage.

These tires have been fantastic for me over the last 5 years. I have over 60,000 miles on them and they're still going strong. Most miles have been from the highway with a good mix of rain and snow in the Midwest and occasional mud. Could not recommend them enough.

This is the second set of K02 tires I've purchased for my 2014 Nissan Xterra. The offroad performance is exceptional when aired down to 18-20psi in rough or sandy terrain. They grip well in sand, mud, snow and the extra siping holds a line on wet and icy roads. The road noise is minimal in my vehicle, which was nice when I drove from New Mexico to Florida and back. I was well over 60k miles on my first set of K02's, and anticipate these will wear the same.

I live in Buffalo NY, one of the snowiest, iciest and whiteout-est places in the country. For many, many years I have used KO2’s for my winter tires. Dont believe the lies. There are two types of tires. Spring-summer-fall tires and WINTER tires. The winter tires must have the mountain with snowflake symbol cast into the sidewall. If it aint there it aint a winter tire. At least it wont save your life in a snowstorm. Dont cheap out. The guy in the ditch, cheaped out. Next, you want thinner tires to cut through the snow. Remember those old wooden sleds with the two metal rails that always sucked because they cut through the snow down to the grass and stopped dead? Thats what you want in a snow tire. Not a wide tire like a snowshoe. You need to contact the pavement to stay on the road. I use 265-65R18 on my Sierra’s and I always blow past the unprepared, wide tired or all season guys on the thruway and a lot of them are 4WD. These KO2’s are a softer grippy compound with a strong sidewall to grip the curves in the road and keep you square in your lane. You will not believe the control you have. Change these out to your summer tires after the snow is gone. You will burn them up on dry pavement. That saves you money in the long run. I get at least 6 winters out of mine. They have some road noise. A hum to remind you you are protected during the winter and a hum to remind you to change them out in the spring. It is not an annoying hum if you realize they are there protecting you. Tires and brakes are the most important things in your life while you are in your vehicle. Buy the best for both. Start with KO2’s. You will thank this review.

My first set of KO2's lasted 102,000 miles! I just replaced them a few months ago. I thought the tread wasn't as deep, and now, I'm sure these tires aren't as good as my first ones. Something changed. I'm not happy at all.
