BF Goodrich AT/ Normal running psi

Have a look at what the vehicle manufacturer recommends.
Actual psi depends on size of tyre, weight carried & type of road, eg bitumen/gravel/sand.
If its running a 205/225x16 about 30 all round empty seems to give
good wear, ride & OK handling. 38psi could result in tyre centres wearing prematurely. A 30x9.5 wears evenly at 28-30 on my Triton but extra load requires more psi especially in the rear say 40+. Following this with a bit of commonsense has given me good results. Cannot understand how you would lose a tyre but if it was at the rear with a BIG load whilst hitting a corner maybe.

My BFG AT's on my GQ Patrol run at 35 front and rear around town, any more and the ride is realy hard and uncomfortable. then when we go away camping with the car laoded down, the front will go up to around 38-40 max as there is no real weight increase on the front of the vehicle, all the weight is i the back.. I put the back to 40-45 depending on how much gear is in the back,, Ive only had them at 45 once when it was loaded with alot of extra fual, and water for an extended trip.. I have never needed to put them any harder yet...
Use the 3 PSI rule as a guide...

I have a 97 Rodeo with BFG A/T KO tyres 225/75 16.

I use 38psi in the front (I have an ARB steel winch bar and Ox winch)

36 in the rear unloaded.

From memory the tyre placard says min 36 front and 34 rear with 205/75 16 tyres.

I have almost 65 000kms on my BFG tyres with even wear. Should be good for another 20 000kms.

Check your tyre placard for min/max pressures.

32PSI, that's what mechanics and service stations set your tyes to everytime you get work done, drives me bonkers! LEAVE THEM ALONE!

It's a rediculously low pressure. I don't even run road cars at that pressure. I run my desert dullers at 40-45psi for round town and highway use.

And no truckster, the rides fine! :-P

Yep - 38 F and 40 R for mine around town - otherwise I end up with bald shoulders and tread in the middle at the end of their life. As Ian says, we should generally take more notice of the manufacturer -unfortunately, a lot of resellers and dealers speak with great confidence, but often have no first hand experience and actually know bugger all. I recently made one lousy phone call to a national distributor for shockers and became more conversant with their product detail than their appointed state dealer ! Bloody sad (but it is SA - a retail backwater in many respects).

G'day all,
Read the tyre! Pressure varies between sizes hugely. I run 35x12.5 BFG's and their maximum pressure is 35psi. My vehicle is permantely packed to close to 3000kgs and tows a 3000kg van with these tyres at 35 psi and has done for 80 000kms and wearing well-probably another 20000 legal k's in tyres although I'll turf them before then as getting less usefull offroad at this stage in their life.

BFG have a specification chart that has a measurment called the Static Loaded Radius. This is the height measured from the ground to the centre of the wheel.
So no matter what car the tyre is fitted to or what load is put on board you pump the tyres up to that measurement. The reason explained to me for this is that the tyre is designed to run at a certain shape to maximise wear, traction, braking etc in normal on road driving conditions. On my 105 Cruiser to achieve that measurement the preasure is around 36 front & 38 rear when empty. So on an empty Rodeo the 32 PSI wouldn't be far off the mark.
For a tyre dealer to say 38 PSI is the one preasure for all is pretty foolish.
The tyre may have rolled off for other reasons as well.
- Is the rim size correct for the tyre?
- Were you driving too fast? ;-)
- The tyre may have had a slow leak.
- Too much lubricant may have been put on when installed.
A tubeless tyre can normally be let down to at least 20 PSI without fear off rolling so at 32 it sounds like other factors.
