Hi all!
Can you please tell me which is the correct pression for a BFGoodrich 265/75R16 mounted on a 80 series GXL ? I'm running it on 32 psi (front) and 36 psi (rear) but I'm wearing them out too quickly on the outer sides ... I'm trying to drive now with 35 psi (front) and 40 psi (rear) but my lancruiser make a lot of vibrations and it is non very confortabe to drive! Please help me ....
Thanks and ciao!

Try somewhere in the middle. I run 38 - 40 front and 36 - 38 rear unless loaded. Although I've never weighed my Patrol front and back seperately, I feel that with the engine, batteries, bullbar, gearbox & transfer plus ME mostly over the front axle, I figure the fronts should have slightly more air.

Usualy tyres will rear on the outside edge, mainly on the front from cornering too quickly, especially with not enough pressure.

We run 32 all round on BFG AT's in that size, unless travelling with load, then kick rear up to 34-36, depending on weight of load.

Normal "weight" on our 80 series, consists of 166L rear tank, and set of Black Widow drawers. In 160K clicks, have never had a heat or underinflation type flat or blow-out.

Can imagine that 40 psi would produce similar effect to having square wheels!!

Hooroo...

With 32 psi (front) and 36 psi (rear) my 80 serie is very smooth .... specially when I'm driving on corrugations .... (I'm living in Kangaroo Island!) .... but now I'm thinking to lift the car (specially the rear) so maybe a new set of shocks can make the difference .....
Thanks anyway!

On my Jack, the BFG 245/70 - 16's pegged out at 80,000 with smooth shoulders - there was still a few thousand left in the centre though ! I now run them around 38-40 psi to counteract this tendency. Of course, I drop them down about 8 psi as soon as I hit the gravel roads - lower again for sand.

The type of wear that you describe is not just caused by tyre pressures. I would be checking toe in/toe out and general wheel aligment also.
Take it to a tyre specialist and ask them to tell you what's wrong

Hi,

I replaced my set of BFGoodrich tyres well after 80,000 km with no abnormal wear. Those same tyres are now used on the Gulf Lander camper trailer. http://www.gulflander.com.au These tyres have since been to the Gulf country and back. On my 80 series vehicle, tyre pressures were set to 30psi front and 32 for the rear. This is what I use for everyday driving around town. If on the highway with extra load, I bump the front and rear up by another 2-4 psi, depending on how much extra weight I carry on long trips. For everday driving around town I find a higher pressure than 32psi in the rear does not absorb the odd pot hole or bump as well. This may also be complimented by my suspension set-up, which is King springs and Bilstein shockies and a wheel alignment check each year.

Good luck and hope this helps.
