i've just put some 235/75 x 15 BFG AT's on my 2000 xcab lux and i'm wondering what pressures people suggest?
i used to run 30 in the front and 32 in the rear (unladen) around town and down as low as 26 off road (20 sand) when i had the factory skinny's on (16" splits)
the tyre shop put 38 in the front and 40 in the rear which ive since dropped to 32 in the front and 34 in the rear (for around town - still playing with offroad pressures)... is this too low?
all suggestions other than "get bigger tyres you pussy" appreciated
I run around 30 on road. Up to 35 if I have a heavy load on.
If Im doing lots of corrugated gravel roads around 25 seems to work well, it soaks up the rough bits a bit more.
Off road around 12-15.
Soft sand around 10. If in need of more traction go down to 8 or lower but must be very carefull to not lose a bead (ie no snakies or donuts )

Why does everyone put more in the rear than in the front?
I thought cause most of the weight was up front, you'd need
more in the front. If the rear tyres are too hard, won't that cause
the rear end to skip more than it does already under fast cornering?
Cheers,
Bart
P.S. In my lux I run 35 up front and 32 in the rear.

maybe they are doing higher in back for loads in the back?
i normally run same all round but thinking what toyotruck and rosco have said, i can see merit in higher in front. mite need to do bit experimenting
Yeah, about 4 years ago I did the Ian Luff Adv. Driving Course
and they were firm beleivers in the higher pressure up front under the motor, particularly under heavy braking conditions.
I used to put 35psi all round, but found that the back end, particularly
in the wet the back would be very unstable. And as I carry no weight
in the ute, and its an alloy tray, if the rear tyre pressures are too high,
the back skips around a bit.
I forgot to mention offroad pressures too.
Sand = 10 - 15psi all round
Rocks/Dirt/Etc = 20psi front (no power steer) 15psi rear
Rallying/Circle Work = 30psi all round
