Anyone running 37" Krawlers? How do they ride?

 

Friend of mine has them. He works at a tire shop and spent a lot of time balancing them, but they still had some sort of harmonic vibration at higher speeds (he speculated that it had something to do with the softer rubber compound - I don't know if he's right or not).

Off road, he is very happy with their performance.

P.S. - he is running the Blue Dot version.
