Also take into account that 2 vehicles travelling the same road are not going to have the same experience, one of those vehicals may have bad luck and other may not, regardless of the tyres or rim size.
When we did the high country in 2011/12, with our GG AT2 255/60/18s, we had 3 or 4 punchures, yet 4 months later on the same tyres going back to the High Country, we had none and we were travelling on rougher tracks.
