Hi all, would much appreciate any guidance regarding tyre pressures for my new bfg m/t 33's. they are fitted to a 75 series landcruiser. There is a track i do regularly that is resonably steep rocky, with erosion wash-outs. went for a test spin 2day and found them a lttle scratchy, but still very good, upon checking when home found they had 36psi (tyre dealer setup). Also whats the effect the pressure has on their road wear, noticed centre is bulging a little at that pressure. Also do a bit of tar and general farm driving, any input would be greatly appreciated.

What were the old tyres and at what pressures did you run in them.

I normally run tyres in the twenties when off road but reduce them even lowerin steep stuff.

The old tyres were 235/85/16 GT muds on splits, i had to run these down to 16psi back and about 22 in front for reasonable traction, any greater and would be scratching a lot, thanks for the reply K&D

I think you have just answered your own question. Why expect a tyre to perform at such high pressures when you usually run a lower pressure on previous tyres. Lower pressure equates to greater traction BFG's are no exception.

Enjoy

I wouldn't lower mine any more than I had to if you want good life out of them. Don't forget a bulging side wall exposes the tyre to sharper rocks and even tree root staking without even discussing increased fuel use. But if you have deep pockets and plenty of spares who cares .....silverback

The Oodnadatta or The Pink Roadhouse as it is also known as has a brilliant guide on tyre pressures for all sorts of vehicles.
Unfortunately my darling husband gave ours to a fellow traveller and I do wish we had it so often it is not funny.
Unfortunately they do not have it on their web site.
May pay to call them and ask for the owner Adam Pate (not sure if I spelt his surname correctly).
He is a great guy and most helpful.
Very informative on tyres for the outback.
Maybe he could fax or scan in and email his list to you.
In fact I might even send him a self addressed pre paid envelope one day and get him to forward another to me via snail mail it is so interesting.
Cheers,
The Wattos.

Great, just what I wanted right now!
No really I will look at it but then I really MUST have a shower and hit the hay.
Will check it out now though and thank you so much.
I'm stoked!

Live life well, you only get one.

Cheers Glenn,
I have printed it out now, fantastic, thank you so much.
I might add my husband was just as happy.
No I had not given him a bad time over giving it away, it is just that we often have a chat with folk that wonder what tyre pressure to use and we think of that chart and it is so handy for out back driving regardless of the name of the track you are intending to go on, it is a pretty good guide.
THANK YOU SO MUCH!
The Wattos (in a real happy state for that shower and bed time now.) Good night everyone I hope you and your loved ones keep well, have a safe & happy Easter.
