I went from running several different duratracs for around 7 years to ko2’s 2 years ago. On road the ko2’s are better, off road, about the same. I’ve put around 60,000 miles on my current ko2s so far.

I like the ko2’s better and they wear better. Under 10,000 miles duratracs are great. After that, very noisy.

Also, the side walls on duratracs are an issue when off roading.
