Question about offroading in sand?

[DWPC]

Check with local folks on airing down. Airing down to about 50% of normal pressure has always been considered SOP by experienced offroaders for sand. I'm curious of the contrary advice posted. Is it a widely accepted practice?

In sand, keep it in Hi, and keep it moving. In Low Range, you'll just dig yourself a nice deep hole.

Carry a recovery straps and gear AND KNOW HOW TO USE THEM. They can cause serious damage if improperly used.

As for portable air, the little 12V compressors are pretty lame; you'd be an hour refilling your 33s. A portable air tank is much more convenient.

Remember: sand is an abrasive!

Question: Is the air-pressure monitoring system just a warning light? Or will it be a nuisance when one needs to air down?
