Hi All,

If traveling through the Vic High country with a 750Kg off road trailer, what approximate pressure should I be running (2004 Nissan Patrol 3.0ltr) with 265/70 16 Bridgestone Dueller All Terrain light truck tires that I usually run at 40 psi on road and that is a hard ride?

Cheers in advance,

Rob and Donna

Just to tell you what I do:
For a vehicle that is the same weight and tyres as yours in the Vic High Country, I lower the pressures to about 22/26psi front and rear. I like the extra long footprint - helps with grip especially when you don't have difflocks. and you like to do a few of the "hairier" tracks. As for the trailer, I don't know - but its not like sand - I expect trailer tyre pressures don't matter as much as they might in the desert.

Hi Phil

Thanks for your comments, I went to Bridgestone website and entered the details of my tyres and there is a video with this guy who advises letting tyres down 20% only, from 40psi thats now 32psi which I thought was still very hard for tackling low range uphills.

20% is good guide, but its best to adjust to the conditions when you need to, and many of the Vic High Country Tracks are a lot steeper and longer than those tracks the guy did in the southern Flinders.

I have done a lot of Vic High Country driving, albeit in my Landcruiser which is similar size and weight to a Patrol. Also I have mud tyres up front, all terrain rear which is deliberate. I believe it gives me the best of both worlds for combination on and off road driving.
In summer, read dry tracks, you can easily leave tyres pressures as is. I use 40psi front and 36psi rear, cold pressures. However if the tracks are rough, you can drop the pressures 20% to make things more comfortable.
In winter it is an entirely different ballgame but most tracks are doable with 25psi front and rear. The lowest I have need to use was 22psi when climbing a particularly muddy and badly torn up track.
Remember to carry a protable air compressor for reinflating the tyres before you get back onto bitumen.
Tyre pressures on the trailer really don't matter, but again deflate 20% to reduce shaking the contents of the trailer too much on rough dry tracks.

GQ patrol, Ossy made bridgestones, vehicle camper trailer set up, with weight around 4 to 4.5 tonne around oz with some harsh dirt roads, Gib river, central desert QLD and such like. I never changed from 32-33 psi, never had a puncture. I spoke to many people doing same trip and was always amased at some of the high pressures run by some people. To me any thing over 36-37 psi is way to high for any condition. The only time i change pressures is on sand and from experience the best quality pressure quage is worth its weight in Gold.

Hi Kiwicol1,

I guess for passenger rated bridgestone's that pressure is ok but LT (light truck) the same size I have been advised by tyre dealer to run a higher pressure of 40psi.
My patrol with standard alloys has 265/70R/16LT fitted. It is a harder ride than the non light truck version same size but more solid construction especially in side wall.
Thanks for your input, I will go with the 20% pressure drop when off road then,

Rob and Donna

The pressures i run are for the LT tyres, sometimes the tyre dealers give these pressures but have never driven the roads and conditions that we travel on.
