Search "4 psi rule"

30psi rear, 32psi front on road

16psi front, 12 psi rear for off road

Ill drop them to 10psi front and rear off road if i need more traction.

Mine are 33x 12.5 STT's

a tyre shop guy once told me that the perfect tyre pressure was one that didn't change much, like 2 or 3 psi, from when the tyre was cold to when it was hot.

I also will be carrying a heavy load on the back a lot of the time and driving through the bush with a load on, but mainly driving on the road, so with that in mind what kind of numbers should i be putting in the tyres?

try 34 in the front and 38 in the back. just check the pressure when they're cold then when you've gone for a drive, check em again and if they havn't changed pressure much then thats the pressure you want.

note, that slightly over inflated tyres will give better economy.

Mean while you go through 2 sets of tyres and have less rubber contacting the ground so more likely to loose traction. I'd be running 34 in front and 36-40 in the back depending on weight your carrying I run 36 in my cruiser with 33/12.5r15 and there wearing flat so the lux being a bit lighter no load run 34 all round.

yep, like everything, its a compromise.
