I'm definitely interested.
I have the PC50 tires on mine at present, and they are suitable for what I intend to use the truck for, and look somewhat genuine.
I received 3 really good condition ones when I got the truck, 2 of which will co on the front, and I picked up 6 tyres from down near Hobart, but they are only fair to rough.
Not sure if they would be good enough to pass a roadworthy, as they have fairly deep tread, but were off a cross-country drilling rig and have lots of stone cuts and chunks out of the treads.
Freight might be an issue to Tasmania, but I'll worry about that later.
Greg.
