piece of piss these days, max fuel is 190 klm accomodation not much more.
yes it will square tyres but no more than any other inland hwy, you can ride around in WA on slightly squared tyres as theres only one corner going in and one corner leaving. You could put new set for the trip and keep what you got now and reuse when you get back, but depending on how massively you like to overload your bike you may need 2 rears.
Biggest problem will be dealing with all the grey nomads doin 60 in the RV/VAN
