I know this maybe one of those questions that get annoying to answer so I apologise firstly. My question is we want to keep a guide in our glovebox for tyre pressures and what they need to be when we go over different terrains.

Vehicle type and tyre size will be required for any reasonable advise.

Rob,
A pretty impressive rig you have there. I see in your profile a photo of the Birdsville track, did you take the van down this track? I note the photo of your van was taken at Millmeran. If this is the town in Queensland, then I think the spelling is Millmerran.

Hi Robert H2
Birdsville track done with oztent only definately no van that time.
Yes your right I did miss out a " r " in Millmerran, but the oven festival is something not to miss. It is on again this year.

We dont get too tied up in the details,
33" MTZ & 33" Coop AT3.
36psi - Highway
28 psi - Rough roads with a solid surface & corrogations.
22psi - Rocks low range stuff
16psi - Sand
10-12psi - Soft sand
If its not working adjust till it does!!

That is some serious detail IMHO.

BFG AT
40-42 Highway
40-42 Rough roads
40-42 Rocks
18 Sand (or thereabouts)

Good suspension. No flats.

Works for us but everyone has their own methods they swear by too.

Well it is considered a bit dangerous to drop pressures too low if you don't slow down. (;-0)

LOL suppose it is some detail. They are approximate, should have said that.

Those 5 road / track types are basically what we break conditions down to.

Highway - well we all have to do that ha ha.

We have deflators 2 set at 16 & the other 2 at 22, so throw them on for those conditions. They are not accurate but do the job fine.

We go to Stockton once a year and pressures needs to be real low if playing in the dunes. A local wouldn't tell me his pressures, secret men's business! we had 16 and kept having trouble, went to 10psi and never got stuck for the rest of the day. No sharp turns as a bead will pop off the rim!!!

Even though we have good springs and shockies, a road with potholes, corrugations, small washouts etc are so much more comfortable with the pressures lowered from highway settings. Got to be better for the vehicle and the tracks as well.

Some tyre mechanics tell people not to reduce tyre pressures, it damages the tyres etc. The unfortunate customer gets fed up getting stuck all the time and give 4wheeling away. If those blokes had actually been out and experienced where their customers are going they might give better advice.

As pop says speed and pressures go hand in hand.

I agree with Iain M on the psi mentioned above for those tyres

BFG At's ...LT construction

34 Highway (Cold)
I do not drop pressures for gravel roads, but slow down, and drive defensively
20-24 Outback Roads (Hot) lower if needed. (60-80 km/h)
12-15 sand (Hot) 10-30 km/h

Standard thing, drop pressures drop speed.

Cheers
Bucky
