Love my duratracks! got 76,000 on them... had them on trails all over CO., Moab, Wyoming, and Montana.... Snow, Mud, ICE, Rock, Dirt, Gravel, In rivers... they are the best all around tire I have owned.
I will be trying out the NEW KO2's when the size I need comes out. Because I loved my old BFG's too... and I'm willing to give them a try.
BUT... I also got drawn in the Rocks to riches contest on the other forum and I get a free set of 4 tires
(I actually am ashamed to say... I'm getting pretty old now and have never been drawn in a drawing before! A record in the early 80's I think was my last win! ) So it was a Christmas surprize! But I don't think any of the 35 sized ties are out until March...
I will be able to compare them in all types of conditions and compare the two tires.... I must say the sidewall strength looks really tough on the KO2's.... and was/is a concern for some on the duratracs... but mine never failed me. the Ko2's will have a tough tire to beat!
