I have had to replace the 17-inch tyres on my 2009 Falcon G6 after only 20,000 km. Ford told me they had not heard of this happening before, and could offer no suggestion as to why it happened on my car. Have you heard of this, and if so why does it happen?
It's not unusual to hear of tyres wearing out at such low kays on heavy cars like the Falcon. Tyre specialists strongly recommend that you balance and rotate tyres every 6000 km or so on a car like the G6 to get decent tyre life.
