Following many positive comments on here, I fitted Cooper Zeons in 255/55R19 from new. They've now done 20,000km including trips to the High Country and the Flinders Ranges. I've had no problems with them chipping and no sidewall damage. Overall I've been very happy with them and can recommend them as a touring tyre.
I have more confidence in the 19"s now than when I bought the the D4 and feel they will get me most places I want to go. I would still prefer some 18"s though and when funds permit, that will be my next investment.
As for availability in remote areas, yes its a problem. Just carry a second spare.
Cheers,
Jon
