Bridgestone AT tyre pressures

Use the 4psi rule, ie start from cold and run the tyres untill hot then adjust from there

When travelling on rocky or corrigated roads that go on for some distance, we reduce our BT tyre pressure down from the 40psi highway pressure to 25 to 30 psi and the F250 from 50psi down to 30psi.

Both vehicles seem to like the tyres at that pressure but we have no expert knowledge to back it up.

I think Brian is close to the mark.Done about 45,000klms on dirt,no flat tyres.Two flat tyres on the tar,One from a screw,One from a kangaroo bone.We rotate our tryes every 10,oooklms including the spare.Running Coopers on the landcruiser and Bridgestone on the BT,very happy.
Gibb River RD.Was there for awhile last june july.Take it steady,Watch out for right angle bends that drop down into creek beds,low gear accross some as they have large holes concealed by water or bull dust.We found the biggest problem was LUNATICS in hired 4x4s that try and do the Rd in 24hrs.Eight 4x4 roll overs in one week.If you see dust approaching try and pull over a let them go.We had one idoit overtake us in a sedan down through a creek bed with a trailer on.We still dont know how he got past us.Anyway two creeks up the road here's the trailer in the bush with no axle.Anyway enough rambling,have a great trip and take your time.Lots to see .Bob

Your not wrong about the lunatics.
Two years ago we had the hired 4x4 heading towards us at a million miles an hour then followed by 11 more!!
Couldn't beleive it.
All the vehicles behing the first travelled in the dust. They wouldn't have seen a thing, but as you say they did it in 24 hours.
Leave minimum 3 weeks for the GRR would be our recommendation and a copy of the latest edition of Ron and Viv Moon's book (about $30) is worth.
