Spare on roof-------Entire tyre and rim or just the tyre carcass

Thanks Drew,
Weight is a concern, especially because of the small fuel tank in the Jackaroo I have to carry 2 jerry cans as well.
William

Good idea with the tube in the case ..... thanks!

g'day Drew,

I also have alloy rims on the Nissan.
Our local wheel and tyre supplier gave me a few rim protectors.
Apparantly, when they receive their new rims they are packed with these hard plastic rim protectors that stop the wheel getting damaged if they are dropped during transit. Just slip them over the front edge of the rim to stop any damage when using the tyer levers. Works for me.
Cheers Nifty

Hi traveller2,
the inflated inner tube sounds a good idea.
William

Hi Signman,
Good point about the compressor, I have one that inflates ok but will have to check how it goes reseating a tyre on the rim.
William

G'Day Bill,
Your right about the weight of the thing, I busted a valve putting it on the roof to test the positioning of the thing.
You had to mention Murphy didnt you, now I know I will be in trouble.
William

Hi Kiwi & "Grenade"
The weight factor is starting to cause me some concern.
I dont think the Jackaroo's roof is rated much for weight, and by neccesity we have to carry a bit on the roof any way.
Including the Black Wolf Turbo 240 you recommended so highly.
Planning is progressing well, I have 2 days off work before we head off so plenty of time to panic then.
William

Hello Kiwi Kia,
The Jackaroo is a TD and needs all the air it can get.
Mind you if we have to travell in the evening it wouldnt be a bad idea to stick the tyre on the front for a extra bouncy bullbar. LOL
William

Hi Steve,
Bugger, everyone keeps on mentioning Murphy, you can keep him for yourself.
Your right though it never happens at a good time.
William

Hi Darian,
I have the Rhino platform rack on mine.
Touch wood I have never had a puncture with BFG's.
Allways a first time.
Looks like just the case for me.
Just had a thought, less weight on the roof more weight in the car eg. a case of BEER.
William

Yep - the BFG's have been very (very) good to us on our bush trips (but they were probably only repaying our very good treatment of them in the first place :-o) - the Cruiser we have now came with Coopers but I'll probably end up on BFG next time - why change a formula that works for us ?

Exactly the reasoning behind me sticking with the BFG's.
Tyre dealer was very keen on me getting some Coopers but I thought i have never had a problem with the GFG's so why change.
William

G'day Oldbaz,
Its the combined weight of the tyre and rim thats a concern.
The 245/70/16 all terrains and the steel rim wiegh a ton plus the 2 filled jerries when actually crossing the Simpson.
William

I think people worry to much about what they put on the roof and not eneough about driving to the road and vehicle conditions
I safely carried 6 x jerricans, 2 x 285/75/16 tyes and rims, 4kg gas bottle and a box of recovery /spares etc etc all on a steel roofrack over the cape, kimberly, simpson etc . this was in an 80 series lc. in the old 60 series I carried a 10 ft tinny and outboard as well right around the gulf and back home thru the centre.

now I tow a CT instead.

a 285/75/16 tyre on a std 8' toyota rim weighs 33 kgs

a full jerrycan is 20 kg so your combination(Tyre/rim and 2 jerries)would only max out about 70 kg.

BTW you would not believe how much lighter a flat tyre feels against one with 50 psi when you are lifting them on and off the roof.
cheers
Howard

Hi Steve,
As mentioned earlier I will have a bit on the roof allready.
So I think just the tyre will be the go.
I suppose I will trust to luck and hope if I do get a flat I can plug it.
William

Hi Chris,
I suppose on the roads leading up to the start of the desert crossing there will be places to get a tyre or repairs done.
Its the thought of getting stuck in the middle of Woop Woop which is a worry.
I suppose having the ability to repair a tyre would take off some of the pressure.
I could be wrong but I imagine it would be very unlikely to get a tyre wrecking puncture once in the Desert.
William

Hi TDB,
I will be travelling with my wife and teenage daughter and my 78 year old Dad and his wife.
Dads too old and my wife is vertically challenged, so it would be up to me.
I am not looking forward to lifting possibly up to 30 kilos.
I think the tyre only is the way to go.
William

Hi Phil..
"In a group where you can share spares, then a single spare is often OK"
Not having a go but- ever tried fitting a 5 stud 100series wheel, onto a 6 stud 75 series...

Fair enough :-)))

But we look at what vehicles are going.
If someone wants to take just the one spare, then we look at what is compatible in the group. Most 6 stud rims are interchangable (Toyota/Nissan/Jackaroo). Tyres are easily swapped between 5 and 6 stud rims. Most people I travel with these days are on 265/75 or 235/85 or 750R16 tyres, and drive Toyotas. And punctures are uncommon.

Agree Phil with the one spare but only when using quality tyres with plenty of tread. With tubeless tyres one has to totally destroy 2 to be stuck & in reality the vast majority are simply plugged these days.
As for fitting a 5 stud wheel on a 6 stud it's simple, just swap the tyres on the rims. Problems only start to arise when trying to fit a 17" on a 16" ;-))
As I've mentioned before in 27 odd years I've only ever destroyed 2 tyres beyond repair & with the vast improvement in the rubber I run on now I'd have more chance of winning Tatts than wrecking 2 between towns where I can get a repair done.
2 spares are now carried for cross country runs & going solo.
Cheers Craig...........

Hi Phil G,
Good point about the other vehicle.
Dad has just brought himself a new Prado.
If I remember correctly they have 17" rims, I will check the stud pattern, if we get stuck if the pattern is the same I suppose we could use each others spare.
William

William,
Yep definitely worth trying it out. Stud pattern is the same, and offset is similar. I'd expect that your 16inch Jackaroo wheels won't fit over the front calipers on the Prado, and maybe not the rear. Maybe the Prado wheels will fit the Jackaroo, but then you may get into trouble with wheelnuts - I assume the Prado has mags.

Craig,
I think experience counts for a lot. I know a few people who have flattened 3 tyres in a day, and usually on their first 4wd trip to somewhere like the Flinders. They are usually running Grandtreks at full pressure and 100kph. After that they learn the lesson, and rarely have a problem.
