Yardie creek to Coral Bay

Usually it's inexperienced people who read or see something on tv or in a mag that snowball things making false claims that not letting tyre pressure down when off road will contribute to track erosion that's how things get blown out of proportion. It has a lot to do with the track surface and how steady or lead footed the driver is like deliberately spinning tyres spitting out rocks etc, the tread pattern width weight of vehicle etc. Yes by all means tyres should be adjusted to suit but I like to see genuine evidence where running on a firm surface no matter where it is there is any so called track eroding difference running with different tyre pressures.

I'm not against letting tyres down but don't like it when people make false claims which gets the media on it's high horse then tracks get closed because someone said the wrong thing.

After 4WDriving for almost 40 years, being in a local 4WD club for over 20 years and a prior job being a 4WD instructor with Cert3 qualification, I think I have perhaps a tad of experiemce to comment.

Road tyre pressures on hard terrain without tyre spinning does not contribute to track errosion or corrugations IMHO. But lowering tyre pressures shows mechanical sympathy for the vehicle and its occupants.

But when it comes to soft sand and in particular sand dunes, it is simply irresponsible not to lower tyre pressures.

As a rule of thumb, if one can proceeed on a track without any wheelspin then you are probably within an acceptable pressure range. But if you have any wheelspin , this typically indicates one needs lower tyre pressures. YMMV.
