instead of spare tyre?
 
Hi Guys, as I have upgraded to 20'' with 40 profile, my tire diameter is now alot larger than my spare tyre(16'' original spare)

So it would damage the Torsen-Differential, if I were ever to use it I guess?

So looking for alternatives... I came across this: http://www.slime.com/shop/power-spai...air-kit-70004/

Can this be used?... seems to me like its the best alternative, any thoughts?

Depends on the spare tyre profile, might not be as bad as you think.
Use a tyre site that has a size equivalence/compare "widget" on it, e.g.:
http://www.tyres-pneus-online.co.uk/...ce-advice.html
Not sure what the tolerance is on Torsen (5% maybe).
If it's too far out just get a different profile tyre (used will do - plenty around at low prices) on the spare.

Personally I like my spare to be the same as the other 4, so both my cars have 2 sets each (summer/winter) of 5 identical wheels. Though the spares are usually a bit "tattier" and maybe not with the best tyres either. :ROFL:

Actually I was kinda excited on the idea of using the sparewheel-room for storage:)

So I will see what people say on the Slime-idea before thinking about getting a new tyre for the spare.

But thanks for your input, much appriciated:)

Also worth noting that once used the tyre cannot be repaired, or never used to be able to as it reacts with the inside and patches won’t stick. Obviously if you got a 20” tyre with 6mm of tread you don’t want to have to scrap it.

I’d be looking to HP says have a look for a 16” tyre the same dia as a 20” then ebay or if you have someone local that deals in second hand tyres as it’s just the spare.

Yeah I get what your saying, as I read this Slime though, it says it can be rinsed out afterwards with no problem(unlike other tyre-inflation-foams on the market) but this might be untrue?

Appriciate the input:)

Well you can anyway, plenty of space inside the wheel, I keep all sort of stuff there... :cool:
Though there's more room inside a 20" than a 16"..... :ROFL:

daviesbike 17th May 2012 10:32 AM

Good for LPG and i was going to do this but the problem is that if you have a blow out there is no amount of foam that will help you there sadly, otherwise i would be happy to keep my boot space and have the LPG in the spare wheel well, only thing is i would be limited to only 40L or so tank

I didn't read that mate sorry. My bad.
Smart cars didn't come with a spare they have a tin of stuff instead.

As Guy says a blow out would be a pain for sure.
Either way the jack that Audi have given you to lift the 8 is more than likely to fail anyway.

Really?... I have lifted mine numerous times with the jack and it has worked perfectly so far:)

Wife's xc90 has a pump with gunk and no spare, or jack!

Goran 17th May 2012 01:07 PM

I never used one of those foamy things so I cant comment on them.
In my previous car (volvo) I had a blow out in Devon, and it was a real pain poolding at 50mph for 100 miles. Since that time I always carry a full size spare.
I also had a blow out with the same Volvo on the Spanish border (I reversed into the toll gate curb, dont ask). It was such a relief to have a full size spare.
Also with the S8 I had damaged tyre in Lyon (bulging sidewall) and again such a relief to have a full size spare and worry free journey back to the UK.

I had a remould winter tyre in summer that decided to demould itself in Germany in hot middle of summer on Passat around 2001-2002 and let the air out so I fitted one of those space saver things that are supposed to be good up to 80kph(50mph). I started off with 120kph(75mph), seemed ok, so I upped to 160kph(100mph), did about 800km(500mi), tyre were smoking at the end and there was no tread left. I was about 12 at the time:)

Goran 17th May 2012 06:45 PM

You went 100mph on one of those skinny spares! :)
Thats very brave, I took one look at the thing and decided to strictly obey the 50mph limit.

Did you see I said I was about 12 at the time??????(just kidding I was 18-19)

But based of previous expierence I would probably not hesitate to do it again.

ainarssems 17th May 2012 06:56 PM

I would like to fit 4 of them and see what it's like.

daviesbike 18th May 2012 07:47 AM

would be good in the snow with such a skinny profile +++haha

Jake242 18th May 2012 10:58 AM

So I guess none of you guys like the Slime option??

It's better than nothing, just we prefer real wheels :)

Night Train 18th May 2012 06:15 PM

I've got something similar in the wheels of my Harley, but having only 2 wheels, I'd sooner throw a tyre away than end up in the scenery, this stuff's meant to seal a hole/ split of up to 1 inch (2.54 cm in modernspeak), never tried it in a car though...

I used mine in a layby, youngest in the back asleep, pishing with rain, spare out the boot with tools, cracked the wheel nuts, jacked up the car, took flat off, picked up the spare offered it on and the bolt holes don't line up :Confused: jacked up a touch more and now i realise that the jack is bending and the car dropping. I battled with it for about half an hour trying to get it to lift but just ended up soaked, cold and extreamly angry, at that point i just wanted the guy who designed it to turn up.

I ordered one from A8 Parts too but when it arrived it too was bent, a quick call and with no problems another was sent out, this one is still in the boot (although bent now because i've used it) along with a steel one i found in the shed from something.

They may well be ok on a workshop floor or similar but i definatly wouldn't be putting anything under the car i wouldn't be happy getting crushed

That can of slime, urrrgh. :eek2: I prefer a real wheel. Even a space saver (wheel barrow) tyre is better. My BMW came with no spare - the original owner ordered it without.

I've since bought a used spare, same alloy and tyre size as the rest. With my S8, I've never used the factory Widow Maker, 1,858 kilos being lifted by that thing gives me the shivers. I purchased a hydraulic bottle jack, a lot safer, small enough to fit in the spare wheel recess and it doesn't tilt in use.
