Any advice on the tyre pressure for Goodyear Wranglers. I purchased a new Jack with Wranglers as standard and was told by the dealer that 30lb/ was the correct pressure. Nice and comfortable to drive but at 10k I noticed a bit of wearing. Went to my local Bridgestone dealer and he told me to run them at 38 rear/ 36 front ( seems to be what I read on this site ). That was 18months ago and I just noticed that the front tyres are just about rooted, and have only done 28k. They are wearing badly on the outside and are showing wear in the middle. At this rate I would'nt expect to get 40k out of them. The car get's a wheel allingment at very service.I get sick of reading that someone got 80k out of these because I know I wont!!. What do you reckon?

How big are your tyres ?
I doubt its the air pressure causing the trouble.
Im told most vehicals are set up for o/s driving and here in oz we have a different camber angles on our roads that can lead to extra wear on tyres.
Apparently the small standard size tyres dont show it that much only the larger tyres.
This can be fixed but may be expensive !

Also rotating your tyres regular can help as i think its only one wheel thats affected. (I had this problem on my Hilux)

Nobby,
I'm guessing you are talking about the standard Wrangler AP's on the Jackaroo. The factory specified pressures are 31psi/210kpa in the front and 35psi/240kpa in the back. I had BFG A/T's installed when the car was new and settled on 36 front and rear.
Get a wheel alignment done by someone who is capable of aligning a 4WD or truck. A lot of Holden dealers aren't setup for this. For me, Bob Jane's at Blakehurst fixed alignment problems I'd been experiencing for the first 40000km's, that my dealer couldn't fix. Best $44 I'd spent. If I had this done much earlier, the BFG's would have easily gone to 80,000km instead of 58,000km.
As it turned out, I wore out the shoulders on all 4 tyres because I religiously rotated them every 5000km.

Nobby,
Sounds like you've got a serious alignment problem. What does the car track like?
Mine's neutral, very slight drift to the left if the roads heavily cambered. My '99 V6 has still got 2 of the original AP Wranglers on it. They did 40 000km on the front and are now on the back at 86 000km. Should get another10 000km out of them. Only had one wheel alignment at 40 000km. The original fronts wore slightly more on the inside. I run them at 32 psi front, 34 rear when lightly laden. Replaced 2 of the AP Wranglers with Michelin Synchrones and very happy with them - quiet, good road grip and good grip on fire track type roads.
