Put 305 ridge grapplers on my jk before the winter. they did real well in snow and ice and are fairly quiet. MUCH more so in all depts. then the bfg mud terrains that came on it. Well I bought a new truck and had them put a set of 2756518 ko2s on it before I took it home. I had a few sets of the old ats but never a ko2. I have to say that there quieter and even better on the snow and ice then the ridge grapplers. Now the ridge grappler IS a more aggressive tire and id bet in pure off road situations it would be superior but this does have me second guessing going away from bfg for the first time in my life. these ko2s seem so far to be a big step up from the older ones. Now I guess you have to take into consideration there totally different vehicles too. Hard to compare a extended cab 4x4 truck to a jeep.
