Which Tyre pressure do you run

[Magilla]

I had the Factory HT,s and got a good run out of them, 28000 and still some left, I ran em at 34 all round pretty much.
Now I have Some Micky Thompson ATZ 265/75 what would you run, my mate at the tyre joint says 34 and he knows his stuff I think, but I will ask you lot any way.

Hey there when i had my 265/75/16 MTZ's fitted i was told by the tyre dealer to run 40psi around town then down to 28psi for general off road.
cheers

[YogiOz]

As per the book for me....

[Magilla]

GLXR Silver how are they wearing or is it too early to tell

[GLX-RSilver]

Very early to tell i've only got 2500kms on the clock. The tyre dealer said i should get around 60,000kms from them.

I'm running 245/75 R16 Cooper ATR's. I run them at 36 psi on tar and 28 or gravel/dirt. Had them on for 35000km now and they aren't even half worn yet.

mid-30's here - 40psi would shake the fillings out of my teeth!!!

[Buzzy]

same as subi

Mickey Thompson ATZ 245/75/16's and the tyre bloke put 34psi into them. Seems to be a good ride, (even on a rough track - definitely much better than what they come with from the factory).

I've got bfg 255/70/16 and run 38-40 in the front and 40-42 in the rear. I usually go a couple more in the rear when towing the trailbikes.

[dezman]

mate i'm running same tyres as you with 35psi all round, same as when i picked them up

[Magilla]

Sounds like I am heading up the right path guys, thanks. Just got back fom drinking beers and playing darts with the guy, how could I have questioned his info.

Mag - put in what you think ya should be running for the load you're carrying. Run it down the road at highway speeds for around 20km. Pull over - check pressures again while the tire is 'hot'. If you've got the correct pressure, your psi reading will now be 2psi higher than when ya started.

More than 2 psi (eg: gone from 28 - 33), you started with too LOW a pressure.

Less than 2psi change - you started with too high a pressure...........

Went for a run out onto the Newnes Plateau after my 15k service and my ute was bouncing all over the place on the corrugations and potholes. I pulled over and checked the tyre pressure, the dealer had inflated them to 45psi.......in 10ply Cooper STT's!!!!

I run 35psi on road and have some Staun deflators set to 25psi for general offroad......and some set to 20psi for sand and mud.

[Magilla]

Thanks HC will try that

[FreestyleCab]

BTW, I just picked up a new tyre pressure gauge.
The ARB508 low pressure gauge.

It has a huge gauge (~90mm diameter) that maxes out at 50psi and its easy to get accurate readings as the graduation marks on the dial are widely spaced.

I just got to find somewhere to store it....its huge!

[High Country]

Thats quite cool - going to those low pressures means it can be used for ATVs too, which really suits me (thats the reason I tend to use the Bushranger digital ones at the mo).

[Magilla]

Reading that low would be handy for my bags pressure too

[High Country]

You are so going to die if she ever hears you say that.........

[dlw]

I am having to run 24psi on road or the edges of my tyres don't touch the road, lost some of the bounce when I go over bumps now from when they where at 29psi. running General Grabber AT2's

[Buzzy]

24 pound?
Shit! Near peal the tyres of the rims at highway speeds if your running that.
Next time you finish a decent road drive jump out your truck and have a feel of how hot the sidewalls are.

[High Country]

Thats UK 'on-road' though Buzzy, going from traffic jam to traffic jam...........

[dlw]

I will probably put them up a bit, but they don't sit on the road properly when at higher pressure which was only 5psi higher.

[dlw]

HC your not far wrong

[High Country]

Put a chalk line across the tread then run it down the road a bit........
