26ish......

I'm with Voxy - we usually run 26F and 28 R, on the 245/70/16 BFG's.

Hi Birdy,
I'm running the same rubber as you (on a Troopy) & (you will find tyre pressures on this forum is a very contraversial subject) it all comes down to road conditions (bitumen,gravel,sand) & the load on your vehicle (light or heavy). My vehicle is loaded heavy (full tanks, camping gear) & I run my tyres hard on bitumen (45PSI back/40PSI front) & drop the pressures 4-5 PSI on gravel. I also go by the 4PSI rule - the tyre pressure when cold should not increase more then 4PSI when running hot. Using this method I'm getting good milage out of my tyres. If you are travelling long distances mainly on bitumen (70% bitumen/30% off road) on your trip then IMHO you need not to go for an aggressive tread pattern. Hope this helps. Cheers.

Hi Birdy
This was debated a few days ago on thread 43368.
Cheers Steve.

Hi Birdy,

In a Ute, Traytop which is usually heavier in the rear than a wagon, I run 24F and 28R. In a wagon I would change that to about 26 all round, GRR and CY the same, and yes I wouldn't use ATR's on either the GRR or CY

Looking over old threads Tires and tire pressure get lots of different replies.

In my experience, part of being a ringer on cattle properties when I was younger.
Driving Toyotas that hardly ever seen a black road.
Adjust tire pressure to the road you are driving on at the time, wet / dry or corrugated.

Everyone can say this pressure worked for me at this time, but it could be totally different when you are there on the same road.
Defiantly softer tires are more comfortable, but are more prone to side spiking as well.

If I plain a big trip I like to have new tires. One big trip was when we done was from Airlie beach out to Longreach then up through to Cape York, down to lawn hill, over hells gate road house road all the way to Darwin. Not one flat tire.
3 1/2 Months of driving.

Couple of the biggest killers of tires is speed and tree roots.
I even seen allot beads blow on cattle grids.

So my advise is take a good compressor and adjust as you need.

Are your ATRs LT construction or Passenger?

I made the mistake of being sold Passenger construction and the sidewall bulge is appalling when you drop the pressure. The tread blocks also rip off like cheese on rocky surfaces.

I destroyed 2 ATRs on a recent Simpson/Flinders trip and after much complaining to the Coopers distributors they agreed to refund me the balance of the tyre warranty on the two tyres.

hi birdy

always measure the foot prints of your tyres, make sure they are the same.
depends on what wieght you are carrying ( heavier in the rear the more air required ) to give same foot print as the front (with less air) you will get a lot more out of your tyres and a lot better ride, enjoy your trip

I did the Gibb river rd 2yrs. ago I found adjusting pressures for ride and traction was the go.All so, stay in the middle of rd.where the rocks are worn round from traffic. It might be rougher but no pointy ones in your walls.CROCKET.
