Be warned - tyre sealant/inflator in the back of your db9
Discussion
I used the inflator and sealant as I had a puncture in a rear tyre the other day. I took her in to get all 4 wheels and tyres replaced (not because of puncture, already had her booked in for new alloys) and thought I'd order a new hose pipe for the inflator while there (the hose gets filled with tyre sealant). I got told that the sealant ends up making its way through the entire pump which renders the whole thing useless. Thus you can't just replace the hose, you need to buy the whole thing for about £165.
Had I have known this, I would not have bothered to use the sealant and just bought some Halfords off-the-shelf stuff like this: http://www.halfords.com/webapp/wcs/stores/servlet/... for 12 quid. I would then still have a perfectly serviceable tyre inflator. Just letting you guys know in case you fancied saving yourself a few bob.
I'm not going to replace the 'official' unit at £165, but will be buying a can of that tyre sealant and a £30 generic tyre pump.

Thank you for pointing that out.
I think I will leave the original just for show, and buy the item that you suggest. Certainly not have a replacement every 3-4 years, on a service advisory basis.
This absence of spare wheel lark, even occurs on some cars that still have a recess for a spare wheel ! "Don't worry, our car maker employer, saves money and the customers will never find out unless they have a puncture."
There is of course justification with our Aston Martins, because a spare wheel would probably use up the entire luggage space.
Is it true, that using the gooey stuff on a puncture, then renders the tyre unrepairable?

The one they give you in the Vantage is the Continental one, you could buy it for about £40 or 50 a few years ago.
I had one for my 911, so I could use the spare tyre space for more luggage when touring. It was a space saver anyway, so pretty useless.

According to the conti website I just linked you can replace just the sealant, so maybe AM just don't sell it individually? The units look the same (I can double check tonight if anyone cares, I've got the old conti one in a cupboard), so probably a replacement conti gunk canister will fit.
Do you reckon there is a weight saving theory going on here ??
When I send my car in for a service I make sure the sealant / compressor is NOT in the car otherwise they will automatically renew the gunk - at considerable cost - which I have zero intention of ever using.
AFAIK the tyre is unreplaceable once the gunk is used

I did wonder when I saw this in my last Vantage
Never has cause to use it and I usually have foam cans with me as well.
Me thinks I will be removing it from the car and just sticking some cans in there.
Phil - it is a myth the tyre is goosed once this is used, the tyre monkeys don't like cleaning it up but it does not affect the tyre (running on it when flat or where the puncture is may well do though
)

Just had to change one on one of the vans because the gunk was used on a puncture - perhaps the guy was just taking advantage of my vacant expression Never has cause to use it and I usually have foam cans with me as well.

Furthermore, TWO new tyres yesterday on the Beamer - a 225/45 R17 91W front and a 255/40 R17 94W rear - because they had punctures......and they're runflats

Expensive times

BTW Mikey, they will replace your gunk at the service point even if it hasn't passed its use by date - so long as it will before your NEXT service date. Best to remove it before you hand it over

Utter bullcrap. The Aston unit is just a Continental Tire unit rebranded like the CTEK charger is rebranded. The sealant is replaceable and use of the selant does not render the pump useless.DB9VolanteDriver said:

It kind of makes sense that the hose would get bunged up after the gunk dries inside it. Can literally just replace the gunk and the hose will be fine?This whole unit/idea is crap!
Got a puncture on my vantage before Xmas, tried to use it and it was a waste of time.
Got the AA out who agreed it was useless. Only works at certain temperatures, with punctures that are so small that it'd have to be a slow puncture.
In which case you would need it!!!!
My opinion. Buy a 5th matching wheel with good tyre. Keep it at home.
Get a puncture? Ask a neighbour, the Mrs, a friend, to bring to you with a trolley jack.
Make sure they have a key to your garage (have multiple people at your disposal), and know where/how to jack your car up safely/correctly.
Unless your a long way way from home, this will save you time, money, inconvenience and a serious messy affair using that crap they give us instead of a spare!
Made me angry at the time, as you can probably tell!

Indeed. I bought a refill kit from Tire Rack when the canister on mine expired. The refill kit comes with a replacement hose. The pump can be reused ad-infinitum. Jon39 said:

My tyre guy told me that some goo/latex does render the tyre useless as they refuse to change it. The Holts stuff in one of the other posts is one that they tell me they can wash out and repair the tyre.Just to be sure, I've never used the supplied goo. Had the same in my new Audi, just bought two Holts cans instead. That means I use the inflator only as a compressor.

There seems to be some confusion about all the different products out there. Some tire changers will not even touch a tire that has been repaired with a sealant, because some sealants are flammable and they believe there is a risk of fire or explosion in case of a spark. Make sure to use a non-flammable product and keep the can as evidence.
As far as re-using the tire, again some installers won't because some products create a sticky mess inside the tire that can be very difficult to clean. The Continental Tire ContiComfortKit product used by Aston uses a liquid latex that they claim solidifies into a rubber sheet (once driven for a few miles) that can be easily peeled out of the interior of the tire so that the tire can be patched and re-used. Be warned, however, that the use of the ContiComfortKit can cause damage to your TPMS sensor thus requiring a replacement.

Have read of how conti suggest you remove the sealent after using the kit and you will see why you cannot reuse the tyre 


ContiComfortKit Website said:
The liquid sealant can be drained off prior to tyre demounting. To do so, drill a hole of at least 10 mm size in the sidewall at the point of sidewall/tread transition whilst the tyre is horizontal.
Use of sealant on damaged tyres linked with a tyre pressure monitoring system may lead
to error prompts and incorrect readings by the air-pressure sensor. When replacing such tyres,
make sure you observe the vehicle manufacturer’s instructions with regard to the sensor. In case
of doubt, you are recommended to replace the sensor.

I've always been lead to believe thst any tyre sealant leaves a latex covering on the inside of the tyre. Due to the difficulty in being able to sucessfully remove the residue to allow bonding/'keying' for the cold vulcanising glue to apply a conventional mushromm style repair patch. Hence why is it classed as unrepairable by most tyre shops as they cannot (or will not) guarantee the quality of the repair.
ETA.... Rich drove his V12V home from somewhere in France to Chester after the Spa trip with a tyre full of sealant and it held pressure for several days plus a few hundred miles too.
