CT Tyre pressures on soft sand

[weeds]

Off to moreton Island Monday week and towing the camper across to the eastern beach on middle road.......I have done plenty a driving on sand without trailer and always lower tyre pressures, that's a no brainer.......

Haven't really towed on soft sand....soooo

Leave CT pressures at road pressures, I'm thinking less surface area = less drag. The only time I towed on soft sand at DI the trailer didn't seems to sink in the sand.....or

Lower the tyre pressures so that the trailer floats a little more......would there been any increase drag? Happy to be convinced if this is considered best

I don't have too many killer wasps to play with with the tug

lower tyre pressures which increases surface area of tyres which spreads weight = less sinking feeling.

Running CT Pressure at same as front tyres of Tow Veh. seems to be a reccommendation from a lot of people I've met.  As well as Magazines, Country Mechanics etc..

I drop mine to around 18-20psi for the bigger foorprint, and we haven't been stuck with the camper yet.

 The CT would be lighter than the tow vehicle so you may have to go a bit  lower in preasure to get a simlar footprint ..
Our old camper was about 5 psi lower to get the same ..

Absolutely drop pressure in trailer tyres . If don't it will be like dragging an anchor. Deflate and the CT will roll/float/follow your 4wd far easier. There is no middle ground or other answer for this topic(what a relief??!!) so just do it. 16-18psi good recommendation.

I must check what pressures I'm currently running in the camper.......have never checked them since I built it

I will be going straight 16 on the tug......the trailer will have next to no air in it

x 1000 obsolutely

Ran 18psi a few years ago all over Fraser and no worries. Dropped our caravan to the same to go to DI and it just floated over the sand. Don't be scared to experiment with the pressures. One thing I do is check the tyre pressures the next day as I find when I have lowered them it is after a run and the tyres are hot. The next day I have found them to be a bit low for my liking so pump them back up to 18psi cold. Hope that makes sense.

Rule of thumb....

The trailer tyre footprint shoud match the tug's tyre footprint........

ie. tug footprint is 250mm long, trailer tyre footprint also 250mm long.

As to "what pressure" is like the old " how long is a piece of string"...........

I measured mine and there is 30mm difference on my hi way pressures........would hate to think how much air I need to make my trailer the same as the tug

I have 235/85/16's fitted all round however the tug has MUDs and the trailer AT's and look to be the same rolling diameter.

Might have a play with pressure today

I have the camper tyres at 20psi, and don't bother changing.
