It's been a few years, but in QLD it's something along the lines of using equipment in a manner other than designed etc etc.
Whatever it was, we were able to deny claims and have successfully defended that denial in court.
thinking about it now, one of the ones I remember was an old landrover that rolled at high speed because the tyre came off the rim on a long curve on the highway.
Whatever the case, there are aftermarket rims available of the correct size, bolt pattern and load/speed rating that will take a tubeless rim.
