Hey Guys,

Well the car is ready for the big lap around the block. One question.....would you use the OEM (above mentioned) tyres for the Outback? Our first destination is Birdsville. We have done some 4WDing with them and they "seem" to be going alright. The car is a 2010 76 Cruiser.

I am familliar with the Birdsville Developmental Track but was asking what your thoughts were. Of corse the speed and PSI of the tyre are important, but do you think they will be alright?

Thoughts appreciated,

Cheers and beers.

Do yourself a favour and get something suitable for the outback, BFG's or something similar. My mate had a set of GranTreks when we went to Cape York last year, he had 3 blow outs on the Savanah Way in the first 3 days. He bought a set of BFG's when we got to Cairns and suprise suprise no more problems. The GranTreks are fine around town but far to soft for the dirt.
Cheers

As your tyres are presumably new I see no reason not to go with them. I just got
back from a 10k trip to far western QLD & the gulf with 50% tread on non A/t
Grantreks on the front with no issues. You have correctly said that speed & psi
are important, I would add load to that equation. High speed, big load & low
pressure stuffs tyres. When you balance those issues it will become clear that
brand & type of rubber are of little consequence. Many will not agree with that
& are even less likely to agree with the 40 psi I run with either, but, like me, experience will shape your views. Enjoy your trip....oldbaz.

If they still have full tread and you're not overloaded, then the AT1's will be fine. I've been away with a few people who have run the AT1's and they are LT construction and better than the average "GrandTrek".

If you do chnage tyres, then upsize to the LT265/75 - because there's a better choice than you'll get with the standard 265/70.

Thanks for the feedback so far everyone. Keep it comming.

Yep Phil the tyres are new as the car has 5000 K on it. The tyre is a LT, so I thought they would be good to go. We have a Kedron van to tow as well. Should of mentioned that I guess.

But 75 series will likely be over the legal 15mm allowable increase.

Pat,
Not so - these vehicles come with 750R16 which is same diameter as 265/75.

I just came back from a trip to the cape with Bridgestone 693's at 34psi. However I thing that the Dunlops should go ok with full tread.

Geoff
