I have been reading with interest reports of tyres wearing out on FG falcons due to, in my case, "toe in" being out of alignment. While I accept that I believe such degradation in less than 40,000 km of normal driving is unacceptable.
As you can see by the pictures supplied how bad my tyres were. I only found out when driving down to the coast on the Queens Birthday long weekend and I got the fright of my life when at 100 km/h I heard the knocking noise of the tyre hitting the fender inner panel. My service book tells me that at 30,000 km service the tyres are checked and rotated, but did they? I can't prove that they didn't, but that aside I want to know how my tyres went from being roadworthy at 30,000 km to being unsafe 10,000 km later?
For starters you need to take more interest in what happens to your car; after all you are the person responsible for keeping in a roadworthy state. You should have checked what was done at the 30,000 km service and made sure everything that should have been done was done. You should also have checked the condition of the tyres before you left on your trip to the coast. Had you done so you would have seen the condition they were in and not suffered the fright of your life. The tyre could well have gone from roadworthy to unroadworthy between 30,000 km and 40,000 km; they could have been just roadworthy when checked at 30,000 km and the extra 10,000 km could have tipped them over the edge. Tyre specialists say that 50,000 km is about average for a heavy car like the Falcon, but that can be substantially reduced if the wheel alignment is out, as you say yours was.
