No I have no vibrations above 65. As long as they are balanced right like mine are they are smooth. Only time you really notice the lugs is at really slow speeds like through a parking lot you can tell that they are aggressive. I've had my truck up to 80 mph and it's just fine. The road noise gets louder the faster you go but like I said before, it's really not that bad for a mud tire.

wow sounds like your pretty happy with them, they look like great tires...i have one more question i need to ask you though...i have heard that they vibrate alot when you go past 65 have you noticed this?

I couldn't be happier with them. They are not very loud at all for as aggressive of a tire that they are. I mean, you can hear them at higher speeds - but it's pretty quiet. If you have your radio on at normal levels it will overpower the tire noise. The handle great on road and even better in off-road situations. You will not be dissapointed in them. They have great reviews on this forum.

im looking at some KM2s and i have a few questions,
what is the sound like on the road and how do they ride on/off road
