@ threedogs
As I said its a simple solution to just run 33's. But that's a simple way out with other issues like fuel usage and reduced power which in the old Q I can't really afford as its my everyday driver to.

Father in-laws is a locked rear, open front. Mine is LSD rear open front.

As I asked above does dropping pressures really help in mud.
I choose 25 psi so I would increase traction a little, but not loose to much height.
As for choosing another line, it was a single line threw scrub. So either go the rut or take the pussy track.. No 2 ruts about it.. :p

I'm not asking for upgrade advise. I'm simply got this issue were would letting down to 15psi instead of 25psi have had helped in mud??

Yes to answer your question and in mud turning from left to right for added traction.
my deflators are set at 16 psi, just keep your speed down. there is a thread somewhere showing
the different foot prints at different pressures, very interesting. Also momentem is your friend too
Is your "Q" coil or leaf???
-
In answer to your question, yes pressures make a huge difference in mud.
2nd issue to think about is the size of the patrol diff/s vs prado rear diff.
Same size tyres big tuff diff on the patrol = less ground clearance.
Not to sure about prado's but general rule for other mid sized yota's like hilux/4runner was that 33" tyres = same diff clearance as 35" tyres on a patrol.

yeah mate tyre pressures make a difference in every situation whether it be mud sand, track racing, drag racing,

Yea I've seen the difference in foot prints on u-tube I think it was.
I just didn't think being mud and getting caught up would be help by lower tyre pressures.
But hay, I can change. Might try lower next time.
The Q is coils all round. I will be modding rear axial shock mounts as they look like nice mud catchers..

You would be surprised at how much difference a few psi can make and the whole diff clearance all it needs is that bolt that hangs down to clip the wright rock or stump to break momentum and lift the wheel slightly to break traction at the exact wright time to stop you in your tracks.
You will also find as you lower the psi the wall if your tyre will widen and place more groves in the mud.
-
As others have noted the tyre pressure will make a Massive difference. The tyre track length could be 50% longer from 25 to 18!
Question: who was driving at the front? If you we're goin first the. You were the Grader and the dirt was moved out of the way by the massive Patrol Diff and the Prados little diff cleared the scraped ground with ease!
I would not worry about compromising the rear lower shock mounts by cutting them off bud, fittin some 285s or 33s will be much less stuffing around and the GQ will easily turn a 33
-
So tyre pressure does help. I'll try lower again next year at the funrun.
It was a fun run so I'm guessing there would have been 20 or so vehicles in front of me. But enough time for the water to flood back in.
I would grab a set of 33's but that's is a fair bit off budget.
And I'm a structural welder by trade so I'll be making those shock mounts tough as nails...

How many of the 20 cars ahead of you we're running little 31s?
