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.

Great tires do good on road, off-road, and anywhere in-between. I have these tires in a 37x13.50r18 and they have far surpassed the off-road/mudding performance of my prior set of 38x15.50 toyo mts. My only complaint with these tires is they pick up about every rock you go over.

I've put 38k miles on these so far & they are getting pretty worn out. Will change out at 40k miles. I've been running them on my company pickup checking wells for almost a year now. Starting & stopping constantly. Rough washed out lease roads & miles & miles of Oklahoma gravel. I drive roughly 150+ miles a day with most of my time spent on gravel. Tires showed wear fast but then held up very well after initial gravel chips. Wore perfectly even across all 4 tires. Rotated every 5k miles. My pickup weights roughly 8500lbs. Anything over 35k miles checking wells out here is a very good lifespan on any tire I've ran. I had very low expectations initially but was pleasantly surprised with the performance

Love these tires. I got 40,000 miles on my last set after beating them off road and on. I drive a Jeep JKU 2017 with a 3.5 Flex Suspension. I've pushed these tires through Mud, Rocks Obstacles and they always perform exceptional. Even had a 2 inch nails try to puncture these tires. I've never had a flat.

I have had KO2s on full size 4WD trucks and I now run them on my new Subaru Outback Wilderness. They are a bit heavier and more noisy but that's to be expected. I have had these across sand dunes (deflated), deep mud, rock and in deep snow and they just can't be beat! I've read a couple state that they dry and crack but I've never had an issue in that regards. I highly recommend them.

I just ordered my second set of these tires. I got 58,000 miles out of the first set and I love them. Great traction and pretty quiet. Now that they are getting pretty thin on tread, they make a little more noise. I expected that though I could probably get another 10,000 miles out of them, but I take my boys skiing so I want to have a fresh set for the winter.

I bought a set of 5 tires for my Hummer H2 overland rig thru Tire Kingdom. The tire buying experience was awful...but once everything was done I forgot about it when hitting the trail. We started the beginning of the Trans-American Trail and gravel all the way. With these tire I had loads of confidence driving up and down the mountains in NC and TN. Getting these was the best upgrade for the truck. Now the rest of the guys that were with me want a set!!!!

Going on 35,000 on sane set of Ko2 35's. I have driven in dozens of blizzards, taken offroad, and plenty of normal highway, and stop and go driving. The tires are quiet and all four tires have worn evenly and not experiencing any feathering. I'll definitely get at least 50k miles out of this set, and look forward to buying another set before the snow comes again next year.

We purchased our Ko2 ALL Terrain tires when our car had 88k miles off the coast of SC. We drove to the California coast threw 30+ state and national parks. Shipped our SUV to Maui HI, and drove back across the country stopping at more parks. Our SUV has 201k miles and we are purchasing our new set of BFGoodrich All Terrain tires!! Simply the best tire on the market.Thank you!

I got the best 7 years of this tires and it's time to get new ones now .
