Welcome to a hard compound E load range tire.
The KO2 is an awesome durable hard pack dirt / off-road tire but I feel the wet and snow traction suffers as well.
Living in sunny CA its almost never an issue, but these days I am finding myself considering other tire options as well.
I'm running C load KO2s and wet traction is fine.
I have about 40,000 on them. They have never had great traction but now I don't trust them at all.
That's great but not every size is available in different load ranges. Some of the most popular sizes are E load range only.
Plus, for those that do off-road and air down regularly, the durability of an E load range is very desirable.
My solution for snow/wet/road and off-road was to simply buy two different sets of rims and tires.
I have hated the KO2 for a while now. Everytime I post that though I get bashed from people saying I can't drive, too inflated, alignment...bla bla bla.
I have had my Nitto Ridge Grappers for about a year now and I have never driven on anything so great. Awesome in dry, wet, snow, mud, you name it, it's the best all around tire. Is there better mud..yes, snow...yes, but is there a better all around good at a bit of everything tire? No
The General Grabber AT2 is a hard tire to beat as far as performance on or off road, and price, the only down side i have is they last so long i get tired of them, and want something different. I had them on my 02 for 7 yrs. still had all kinds of tread left, but they were getting hard, and weather cracked, so i went with the Wildpeak MT, but ended up selling the 02 soon after we got the 17 SR5. I did put the Grabbers on the new ride in the stock size. Very good tire in my opinion.
