Hi Folks,
is there a general guide to tyre pressures on the tow vehicle (100 Series TD) - generally on the tar I run the fronts at 40 psi and the rears at 48 psi cold. I have a 20' BT and generally operate at the 3200 kg loaded.

What do other Boggers do / think?

(PS - I have search the forum but was unable to find any definitive answer)

I have a 200 and 19ft BT

Usually run 40 all around on the 200 and 35 on the BT

I drop these to 30 on tug and 25 on BT when on gravel roads.

Corrugations still seem like corrugations but the BT generally holds up without breakages but never know if there would be no breakage without dropping tyre pressures

Hi Des
We have 265-75 x16 tyres on both van and tug. On tar (usually back roads so generally rough) use 35 front 40 rear, 40 van. On dirt I use 22 front 24 rear, 24 van and if stretches of tar between dirt is only 100k's or so, I leave them at that on the tar and keep the speed down to 75/80. Probably get a bit more tyre wear but it gives a nice smooth ride.

Hi Des,

Hi All,
While we are on tire pressures, what about Chev, Ford etc.
My manual for Chev states std front 60psi and 70psi rear.
I run on these pressures plus 5psi extra on rear and tire wear
appears ok.
I tow a 19ft with a 275kg +/- 10kg ball weight.
What do others find satisfactory? .
Cheers, Ken.

Had a couple parked next to us at Weipa - very despondent, he had just gone and bought a tent to do the rest of the trip to the Cape as his thought his new tough looking Grenade would not make it to the tip.

He and his wife had spent three hours getting dust out of his van and the fridge had also failed. He had dropped his pressures from 60 psi to 50 psi for the corrugations and I suspect that was a significant factor in his problems.

I don't think he really believed me when I told him I was running at 22 psi cold in the van and only a little higher in the 100 series and that we were probably significantly heavier than he was.

So we run 265/75/R16. Normally run 40 all round on reasonable tarred and down to 22 on the really rough stuff and whatever feels right in between- but then your speeds are rarely over 30-40 kph anyway on the bad stuff.

Further to my previous post, the tyre pressures were for tarred road use.
On dirt roads as per our June trip to the Tip, van 25psi, car front 35 and 45 rear.
The pressures you mentioned were ok on my previous vehicle, L/cruiser, but the Chev is a little under 4.1t loaded plus ball weight.
Anything under the previously mentioned factory recommended psis for tarred road use does not look safe.
Tyre wear is uniform and was just curious as to what psi others use on the tanks.
