It has been a long time (FAR TOO LONG
) since I have driven this track. When I last did this, I shadowed a falcon AU that was taking a family from Oodnadatta to Leigh Creek. No problems for normal road tyres but the track was wet - it may have kept the tyres cool. The driver made it through several shallow creek crossings ok.
If you want to know where your tyres are guaranteed to fail, it is between the towns of Craddock and Hawker in the Flinders Ranges. It will shred the BEST off road tyres because I have experienced it and seen it first hand and spoken to other drivers at the Hawker garage with very expensive off road boutique tyres.
