I’ve been extremely happy with the BFGoodrich KO3 tires. I currently have just over 83,000 miles on this set and expect to get around 85k before replacing them. Most of my driving has been highway miles, and the tread has worn very evenly throughout the life of the tires thanks to regular rotations at every oil change. Performance has been excellent in all conditions. They’ve handled off-road trails, sand, and snow with confidence while still providing a comfortable and predictable ride on the highway. The combination of long tread life, even wear, and all-around capability has made these some of the best all-terrain tires I’ve owned. When it’s time for a new set, I’ll be buying another set of KO3s without hesitation.

2nd set of these tires - have the KO2 on the 2023 4Runner and they are on 45+k miles with easily 40% tread remaining. the K03 that i have on the F350 have been great - already taken them on "Primitive" roads and they have been great. noise, handling and traction are phenomenal, especially for a mixed use tire.

nice

I'm sitting here with two of my friends, we all have K03 tires and different trucks. They all shake the steering wheel at 75 mph despite multiple attempts to balance. We decided they are dogpoop tires. I wouldn't have these tires shoved up my worst enemies butt covered in beach sand. Do better... what a pile of crap these things are. Bruce Wylie

I cannot get these tires to balance at all. They have been road force balanced 3 times now and vibration still persists above 65 mph. They also make the classic whop whop whop noise at low to moderate speed that is typical of a tire that is out of round or balance. I've never seen a tire take 16 weights on the wheel and still vibrate. Will be attempting to exhange these for a set of Toyo or Nitto like I should have bought in the first place. These are a great looking tire but that's the only benefit.

Just gad new sett put on sierra 3500, horrible vibrations over 45mph. Road force balanced twice still vibrating to point of nausea. Biggest regret ever total waste of money

Complete junk. Out of round, high road force numbers. Won’t balance anything over 65mph and the whole truck shakes. Never again….
