I have one as a spare, it was after a nearly new Duratrac blew a sidewall and i needed a spare quickly. So i got a half worn one with alloy for a cheap price.
I've had it on a couple of times and you can tell it's on, it's noticeably louder than the Duratracs with it's own hmm/roar.
Good tyre in the mud etc, but not very good on the road for noise and such.
I did have a set of those alloys on my D3 as well. They sit on a slightly different offset so they sat further out and lined up more flush with the arches and the stock HSE alloys which sit in a bit. I liked that slightly wider look they gave.
