Yep got the maxx's on my hilux and have done 2 trips across the country on them and I love them. They have gotten a little more road noise as they've worn but not to much.
I find the grip is excellent for what they are, after all they are an aggressive AT tyre. They can get a bit slippery if I don't adjust my driving for wet conditions.
Off road I've had them up the Creb track a couple of times with no dramas.
So far I've put about 30thou km's on them and its looking like il get the stated 80thou out of them.
