Hello all,
The official planning process has started for our 3 week 6000km wirlwind tour of SA, QLD, NSW, ACT & Vic.
Our vehicle will be a Holden Captiva CX diesel. Stock as a
rock, right down to the Highway tyres, with the exception of a
UHF radio. Part of our trip involves hitting the dirt at
Lyndhurst and running up the
Birdsville Track through to
Windorah.
A wise man (my dad) always said prior preperation prevents poor performance so, with that in mind, I'd like to take away a couple of spare tyres (plus the factory spare). Now, being a company vehicle, modifying it is NOT an option. So please no recommendations about fitting Coopers or Duelers. I have to play with the cards that have been dealt.
So I'm looking around for a couple of steel rims and tyres to take as spares. So does anyone know which, if any other vehicles have the same stud pattern? (Lots of second hand sets of Captiva factory alloys, but everyone wants to sell them as an overpriced set and won't split them.) They don't have to be the same size (17") rims. Carefull selection of tyre profile can ensure the rolling circumference stays the same.
Any help would be greatly appreciated, as even Google has failed me on this one.
Thanks....Fab.

What you say about rolling circumference may be true, but you may strike problems with rims contacting brake components if you use different size rims.
I would be more than happy to go with one spare on that trip, providing the tyres
have plenty of tread & you adjust speed & pressure accordingly. Take a tyre
repair kit for plugging punctures. Taking 3 spare wheels is overkill IMHO, but
your choice , of course......oldbaz.

Thanks Baz.
Tyre repair kit was a no-brainner (already have it). Tyres will have less than 5000kms on them when we head off. Speed will be about 80kmph (max) along the gibber sections. Anticipated pressures would be around 24-26 psi (is that too low???).
Funny you say it's an overkill. My friends always accuse me of "over-engineering" everything. I'm working on the fact that 235/60/17 tyres are probably not available in
Birdsville or the like and if they are, they'd be at a premium price.
Very mindful of calliper to rim clearance, offset (expecially for full lock turns) and a snug fit to the hub. My trade school days remind me that wheel studs are designed to hold the rim on to the hub, NOT support the weight of the vehicle.
Thanks Baz.....peace of mind to hear that 3 spares is an overkill. Kind of glad to hear that actually.

I am in no way critical of "being prepared", but the logistics of carrying 3 spare wheels is quite daunting in itself. Perhaps taking a spare tyre if you think it
necessary. I had to buy a tyre at Mungerannie, & funnily enough, it was only $20
dearer than anywhere else, 17'' for a Prado. Most will probably agree with your
tyre pressure, but I am not a subscriber to lower pressures, particularly when
fully loaded,so will leave that to your discretion. Your speed I agree with, high
speed at low pressure with a load is a disaster waiting to happen.
Enjoy the trip..........oldbaz.

I don't think you will need three spare tyres as you are staying on good high speed dirt roads.
Instead of wasting money on the spares why don't you sell the tyres you have factory fitted and replace them with something more suited for moderate off road driving like an A/T tyre.
The other thing is where are you going to carry three spares?
I would buy a plug kit, an air compressor and run appropriate tyre pressures, maybe even invest in a "tyre pressure monitoring system" as that alone will save tyres.
Sure prior preparation is good but don't go over board.
We have never destroyed a tyre on high speed dirt roads.
Remember locals drive on these roads everyday with 2wd cars with standard tyres.

Thanks olcoolone,
Selling the tyres and retro fitting anything other than OEM is not an option (company car). Strictly not allowed, so to is the fitment of any accessories that leave behind any witness marks etc.
The three tyres would comprise of the genuine space saver which is about as useful as a watering can in a bushfire and two full size tyres on rims. The plan was to stick them up top on the roof rails.
Although, by the sounds of it, maybe one on the roof and the worse case scenario space saver might be enough.
Cheers... appreciate the
feedback. Can't buy experience, hey?

The space saver wouldn't last 50k's out there. I wouldnt even carry it! I remember reading about a Goose who complained to Subaru that his space saver only lasted 30k's on the
Oodnadatta Track when he went up it in his "4 Wheel Drive" WRX. As has been said, speed, or the proper control of it, is your best friend where you are going. There are always arguments about tyre pressures so I won't go into that. But if you drive at a comfortable speed where you can see what's on the road ahead of you, you should be fine. You will be surprised how quickly you can adapt to looking for the big sharp ones and going around them. Where the problems arise are in corrugations where you can't identify the nasty ones. All you can do is slow down and take care. Unfortunately, as the driver, that is your job - let the passengers look at the scenery. Why oh why do car manufacturers insist on selling vehicles that they push as suitable for outback travel and put low profile tyes on them??? Have a good trip.

BTW don't think that you are only likely to strike problems in the "gibber" regions. You can strike sharp rocks anywhere out there, particularly if you go through shortly after the graders. I struck 2 Pajeros about 10 k's apart which had both destroyed both rear tyres on a stretch of road near Wittenoom. We found out later that the graders had just been through. Keep your eyes open!!!

G'day Fab
I've done the
Birdsville, Strezlecki and
Oodnadatta tracks on highway tyres in a vehicle similar to a Captiva so I reckon I qualify for an opinion. If it was me, I'd carry 2 full size spare tyres but not on rims. They are too heavy with rims for the roof racks on a car like yours.
Mine only allows 60kgs and that wouldn't allow you to carry much else up there. A really good investment instead is a bead breaker kit which you only have to buy once and is good for any subsequent car you have. If you have trouble, first I would try limping at 40kph to the next town on the space saver and get them to swap the tyre, and if that fails, you can swap a spare tyre onto an existing rim and get yourself out of trouble, I would run 25psi on a relatively light car like a Captiva and I wouldn't even think of it as low pressure.
You would have to be really unlucky to have a problem if you drive sensibly. I have also found that I get pretty nervous out there on HT tyres when I only had 1 spare left.
The upside of this solution is that the 2 spares are just tyres you (or the company) would have bought at a later date, and the bead breaker is yours forever. Keep your speed down on the rocky stuff. It seemed to me like the bigger forbys can cruise through it like those ice breaker ships doing 70-80+ks or so, but I liked to stay down at 50-70k's. Sandy/clay sections are a breeze if dry and you can up the speed but the rocky sections sometimes pop out of nowhere and catch you by surprise.
Have a great trip
Mike
