FWIW, I had MT/Rs on the XV-JP. By the time they had 5,000 miles on them, they were noisy and squirmy on pavement. I put DuraTracs on it and got vastly better highway behavior, making high speed travel more secure and considerably improving wet weather driving. And they're good in snow. I don't have enough off-road experience with them to give a detailed opinion, but the reviews I've read suggest that they're OK or better in most situations. As best I know, they're at the very top off-road performers of the tires that don't require any significant on-pavement compromise.
