Hi Bogged,
I'm real happy with the tyre carrier. The only thing you have to be carefull of is that it is open far enough before you open the tailgate. Doesn't block the view out the back, you can see the top of the tyre but doesn't have too much of an affect, I'll get a pic out of the rear window tonight if I remember. Mine will take up to a 31, it's got a 30 on at the moment. You do notice it moving a little but it's certainly solid. There is a plate inside the bumper bar that mounts to the chassis, it also has a support that goes down to the tow bar mount, if you have a towbar it still mounts apparently.
I've done the Flinders and the corrugations out to Cameron Corner with it and also Fraser Island with no problems or signs of fatigue. I even had a work light on a stand mounted on it for the Flinders/Cameron Corner, the stand for the worklight split from the continual vibration but the carrier was fine
I got it from Chris at Consoles and Carriers on 0407 319 784 or 03 9704 7673
