750 R 16s

G'day mate just air them down to about 20psi and see how you go. Being a LWB you may need to go lower but it is a good place to start. Like any low pressure driving DON'T turn too quick or you can roll them off the rim.

You could go as low as 8psi but then you would need to be going in a straight line.

I have run a tyre off the rim on beach sand at 12psi

15 to 20 psi is usually a good measure. Start at 20 and if it doesn't work for you go down to 15.

As said, avoid sudden turns

Skinny tyres normally have a longer footprint but not as wide as a tubeless.

Hi Lionel,
You will find that the 750/16 actually bag out better than the 31s.
The popular myth in letting tyres down for sand(and other appilcations)is that it gives the tyre a bigger footprint across the tread,WRONG, it makes the tyres longer and because the 750s have a bigger diamater they will have more tyre to be able to float on the sand.
I have 235/75 16s and they work well in sand at around 20psi ,I have read on this forum members who have gone as low as 10psi to get out of a situation and succeeded.
similar characteristic when driving on 31s that are low but keep an eye on tyre tempreture becuase with splits an tubes in the tyre they tend to get hot if driven a long time
I hope this helps

Shane,long live splits!

hi all ,its always interested me in regards to splits as we are planning a trip a bit off the beaten track later on in the year .
Some of the driving will be on the blacktop ,so what concerns me is how the splits with innertube stand up to the heat of consistant blacktop driving for say 12 hours or more in any one day .
I must admit i am a complete neanderthal when it comes down to tyre changing and although i have the Rand B beadbreaker for tubeless tyres ,i am completely useless at using the said contraption and only seem to be able to get the tyre off the rim .
In regards to splits i have found them easy easy and this is the reason for me possibly reverting to the splits when going out in the middle of whoop whoop .Thanks pete

Hi Lionel, in all my years of sand driving on splits I've never gone lower then 20 psi tyre pressures & that's on radials & crossplys. I've found that is low enough to give sufficient traction. Glad you liked the deal. You got a good buy.Am enjoying the block !!!!!! Cheers.

We have a 105 Series GXL with the standard split rims, and spent all day Saturday on Stockton Beach.

With 8 people in the vehicle, around 20psi was good enough for the northern end of the beach, but we had to drop down to 15psi down the southern end near the wreck. The sand down there was just weird - my foot would sink a good 2-3 inches into the sand straight away..... the poor cruiser was digging trenches almost a foot deep in places - and it was low tide!

It drove fine, albeit a little slow, and at 15psi, the dunes were quite easy to drive up and over. Engine power was the limiting factor, not so much tyres I reckon. There just wasn't enough grunt sometimes to get up some of the bigger ones without backing up and trying again. I did a couple in low range 2nd quite easily, so the tyres pressures must have been fine.

You'll find with the splits you can pump them up a little higher than normal (think 45psi) for long hauls on the blacktop, and the car will be a different beast all together. Fuel efficiency increases, and there seems to be a bit more power than at 38psi. My next tyres will probably be 235/85's on the 16" split rims, just to get a little bit more height.

Cheers,

Chris
