Hi all i am looking for some feedback, i have an 07 D40 Narvara with highway tyres fitted. We are looking at going to Moreton Island soon and would like some advice on whether or not we would would be able to get around Moreton when dropping our tyre pressures to 20psi with the tyres that we have on the car. We will get All Terrains fitted later but are wondering if we can get away with out them for this trip. Thanks for your help
