Thanks MudRunnerTD.

PNG has come a long way since 1995 ... and the changes are happening very quickly at the moment.

I agree about tyre pressure. Most of the time it is not an issue. It is really only when I head out get caught in an late afternoon storm while in the hills ... and even then, we usually manage. I consider the chains an "insurance policy". I hope I never have to use them, but they are there as a backup should I be unlucky.

On my previous vehicle I went for a larger tyre, but found a tall first gear a real pain. So I would like to stick with standard tyre sizes (or get reduction gears). So getting chains should be straight forward.
