Hi Bill and Wendy, our D4 does have 19 inch wheels but we are taking 2 spares - one on the roof, so hopefully this will suffice! We have already taken our D4 and ATV on the Oodnadatta Track, Borefield Rd, the Darling River Run, outback NSW, Flinders Ranges etc and have had no problems. We have General Grabbers fitted, as Cooper tyres did not have a 19 inch tyre at the time. Interestingly on our last trip with the Range Rover/Discovery Club into outback NSW, there were 3 punctures over 7 vehicles - all were Cooper tyres! Thanks again for your help.

Thought of going to a 4 but wanted to be able to have same wheels on the van and tug. Hope that yours doesn't have 19 inch wheels. We saw two up near the Cape, waiting to have tyres brought in because there were none available locally. You are sure to enjoy your time up there providing you don't do anything silly. We thoroughly enjoyed our time there and would go back soon - if we didn't have so much to see elsewhere. Hopefully we will do WA next year after a few short local trips to get to know the new van. Cheers, Bill
