    yes but having highly inflated tyres will dig into the sand which produces even more friction.

    Hi All,
    One thing not mentioned is what is causing the issue, tyres or axle creating the friction. If it is axle you need to fit higher tyres, but can then create launching issuses.

    Doesn't work like, mit spreads the weight thus it sinks less which creates less drag. Best example I guess is snow shoes?

    If axle is dragging in the sand it will make the vehicle get stuck the same way you get hung up on your diffs of any vehicle.

    Snowshoes are a good analogy. You need 'length' increase, and this is where high(er) aspect ratio tyres help. - think about them when you next need trailer tyres, no great gain in throwing about $$$ now...

    I'm guessing your biggest bugbear is RE-inflating, especially after only 10 metres or so. Both time.... and hassle.

    Do the co$t/use analysis of a SCUBA tank and suitable regulator(s) to instantly re-inflate SIX tyres...

    - Compare the time & effort (and fuel cost!) of buying and running one or two decent air pumps... with the convenience of carrying a tank plus a short hose/inflator, which can bring you right up to highway pressure in a matter of seconds.

    If your trailer axle drags.... then find a better launch surface!

    Just a thought.

    In regards to the "PlankTraxs" it's a bit of a jab at the MaxTrax. It is pretty much a "plank" of wood with some roofing screws or the like screwed into it. Costs a couple of dollars compared to the ~$300 for a set of MaxTrax.

    Go to Planktrax - 4x4 Earth if you like to see an example. It has become a bit of an inside joke for anyone that is on the 4X4Earth forum.

    Like the progression from wood to modern material, - plastic crates. - The company name/logo on the side would give it away if left on....

    Great link, especially to the 'necessary' gear... bumper dumper portable toilet

    I've pulled my 2 wheel trailer in the sand plenty of times and have found that deflating the 255's on the trailer gives much better floatation. My Discovery has 265's...I also let them down to about 18-20psi.

    The PSI in the trailer tires depends on the weight I'm pulling but since they're not turning left or right like the front driven wheels of the car I let them down untill they start to bulge a bit. On the road they run at 36psi....off road is about 16psi (or untill they start to bulge at the bottom)

    My trailer and the Discovery both have same steel rims so I don't need a spare trailer wheel.

    Cool

    thanks people,

    all good info, BUT remember whilst the tires pressure are being let down, the TIDE is coming in !!!!

    So i need a quick solution, takes me ages to let 4 tires down let alone 6, at least the ARB air locker will give me a compressor onboard

    ... I'd be interested to know exactly how long it takes to deflate a tyre, by whatever method you use. There may be a faster way, - other than doing it in advance.. or getting in a few minutes earlier so the tide is less of a worry....
