This time next week, we're heading off up the beach (Noosa North Shore & Cooloola). We are hiring a camper trailer for this trip and will be towing up the beach. The only time I plan on going through soft sand will be getting on and off the beach, as well as getting the trailer to where we are going to camp. I believe this particular trailer weighs a little over 1000kg. Tow vehicle is a Petrol 120 series Prado. I'm familiar with the types of pressures that I normally run for the Prado in soft sand, but am just wondering about the trailer? How low would I need to go for the trailer in soft sand?

Would appreciate some feedback from those who know.

Not sure what others do but if I let my car tyres down to lets say 18 psi I do the same wit the trailer. A lot of people say it doesnt make any difference but it does and if the trailer is 1000kg plus it will matter even more.

That's what I always suggest.

All the best

Our Patrol tow's our Cavalier Trailer, all up around 3.5t...... the trailer tyres "track" with the Patrol, and as such we don't lower the trailer pressures. We run the Patrol tyres at 18psi (Pro Comp muddies) and to date have not had any drama's.... that's Noosa North Shore to Inskip Point and Fraser Island including the soft tracks around Happy Valley.... we haven't tried towing it through Indian Head yet... :-))

My theory was that we could always lower the trailer tyres later IF we needed to... but we haven't had the need. If the trailer "tracks" with your Prado, in theory the "soft" sand is now "harder" after your tyres have flattened it and therefore the trailer should roll on over it.

Works for me anyway!

Hi Mark,

We lower our CT tyres to the same as we have the car at and so far we haven't had a drama. Have done this at Cooloola, Fraser and Moreton so it seems to work well for us.

I think it can be a bit kinder to the tracks at a reduced pressure also.

Enjoy your trip.

Brian, running the same pressure seems to be the way to go, from the responses so far. Makes it easy especially with the Staun Deflators.

I also agree on your point re the tracks

Many thanks

Hi ShnogDog

I tow a 1.5 tonne boat through there quite regularly. I let trailer tyres down to about 26psi - thats when they start to bag up. Vehicle tyres down to 18psi or lower if very soft. If you are coming down from the Noosa Ferry dont go down (or back up) the first (most southerly) beach entry/exit track - ok for normal vehicles etc, but go to cutting number 2 (turn north just before beach entry and follow high tide road which is well formed). Cutting number 2 follows a creek bank down to the beach where the sand is hard packed and a lot less steep than at cutting number 1. You should blitz it through.

Have a good trip

Thanks Age, I was aware that there are a number of access tracks. I'm sure the first one gets most of the traffic and would be pretty carved up this time of year.

Cheers Fellas,

I'll go with the same pressure as the car. I think that will be pretty simple. It was what I originally had in mind, but thought it best to check as I havent had any experience with a CT.

Thanks for your responses.

I tow my boat through sand hills down at Ningaloo and lowering the tyres on the trailer does help. One point to watch is to make sure that your air compressor hose will reach the wheel furthest away or you'll have to unhitch or jack knife it so it'll reach.

if you buy an extension hose, only use it for the tyres you can't reach, and make sure you straighten it out when inflating.

I melted my fuse by not doing these simple things.
