i had a set of the original ko's on a toyota tacoma. They truely lasted 50 k miles.

Not, that i just didnt change them, and ran them bald for the last 10k miles. I measured the tread when rotating.

I dont kid around with tires. I had an ugly spin out once on bald tires. So really, when I say i got 5 years out of my ko's i mean 5 real years. Really good tires for almost everything but mud.

I never drove that truck wishing I had different rubber on it. BFG makes a good tire.

I will say, the KM2 is really good, but for a north east winter... My rig may wear these new KO2s in the winter. Im hoping its a soft compound. The duratrac is a good tire. BFG must have taken that into consideration and made a good all weather soft rubber compound tire.
