Tires BFGoodrich or Hifly

I live in Lake Tahoe and I run ko3 all year round with zero issues. Highly recommend them.

My K02s have been awesome for everything I've thrown at them.

Southern Maine here. The KO3s I’m currently running are terrific in both rain and snow. Every bit as good as the old AT3W in both. Only time I went 4hi last winter was on a particularly twisty/hilly part of my commute (narrow two lane rd) and that had more to do with me being overly cautious, not because it was slipping

My KO2s were 5 or 6 years old with plenty of tread left. I stuck with BFG because I get plenty of miles out of them and I have no complaints from the KO2.

I switched from the stock Goodyear tires to E-rated BFG KO2 on my 2015 F150. There is a small but noticeable loss of quickness that you get used to. I also lost 2-3 mpg on the highway. I gained much better flat protection.

The traction is one aspect but proven durability off road is hard to put a value on. K02s have eaten some ugly road.

I had a set and my only complaint was they weren’t very good in mud, other than that they were great.

I bought KO2s because of the hype, 2 sets of them actually. And found them to be very mediocre in anything but dry dirt/rock. They have worn very well but on and offroad performance hasn't blown my hair back.

Can confirm that KO2 are horrible on ice and snow.

I have load range E tires (BFG KO3) on Rock Warrior 17" forged wheels, so I've made that tradeoff too, but am clear-eyed about consequences. Also, loss in MPG and acceleration due to having to spin more weight on each wheel. And incorrect speedometer / odometer readings. And loss in tow capacity (due to giving away torque via taller tires, which effectively decreases gear ratios).
