I suspect that your tyres were the ATR, not the replacement AT+ which is quite different. My 275/55R20 LI 113 aren't fazed by fast, harsh local and outback gravel and D3/D4 owners with the 255/55R19 LI111 size give good reports for outback travel too. Whilst I destroyed one by driving into a lump of limestone on a Nullabor track that also bent the outer lip of the rim, I expect that no tyre would have survived that incident.
