Tyre Pressures and good compressor

Pressures would vary depending on the size of your tyres. Also weight carried.

As for the compressor wouldn't it be better to buy one that is able to be used for your lockers later. Instead of buying a cheap compressor now and a more expensive one later?

My surf is running 10r Bridgstone Desert Duellars. Otherwise same vehicle as yours except I running a 3.0 Turbo Diesel instead of a 3.0L V6.

On road I'm running at 45psi all round.
In the bush, well depends but if it's rough I'll go down to 29psi
Sand, straight to 16psi and lower if needed.
Mud normally about 20psi.

I have a Bluetounge IV under the bonnet plumbed to an air tank and to a quick release connection on the front grill, I tried the cheaper units and kept burning them out, I wouldn't waste my time with the cheapies if I were you.

Your 10.5R 15's are going to absolutally kill cheap compressors as they have a huge volume of air in them.

I've seen a couple of GME TX3200's going for less than $200 on ebay, might be worth looking at those and saving the $$$ for the blutounge.

As for compressor...find an airconditioner compressor and fit that, with some mods you will have a compressor capable of inflating your tyres in about 30 seconds. Message me if you want more info. I have done it myself and won't pay $300+ for a compressor.

Hi Will,

Had an 85 forerunner and ran the same pressures as I did later on my GQ RB30 (GQ weighs 2t)
on road 31 front 29 rear
in bush 20 both ends ( any lower you risk popping bead )
on sand 20 both ends ( never found a need to go lower including hills in inland stradbroke before all the tracks were closed )
in mud same as bush

Got 60k on bridgestone duellers on the 4runner still ok when I sold it and 70k on import highway tyres on patrol, now has BFG's at same and doing ok so far.
These pressures are for empty running, obviously the pressures change when you load up for camping.
Now this is only my opinion but running 40+ on a vehicle this light must feel akin to strapping bricks to your rims, and I feel sorry for the shockies.

Will21, - If you dont mind a bit of leg work get a dual cylinder foot pump. I was thinking along the same lines as you (Air lockers down the track) so i bought a michelin foot double foot pump from Big W (I think) 37.95 and I have on several occasions pumped up all 4 of the 31x 10.5's on my 80 series as quick if not quicker than others with ARB and Big Red air compressors - no joke! I admit its pretty hard work though. - Twigiee
