997 TURBO GEN.2. SPARE WHEEL

[X911NJS]

Hi members,
Are there any members who run a 997 Turbo Gen.2. that have spare wheel/spacesaver which they did not
purchase from Porsche,ie an alternative if so I need the part number and any information please.
I am really not keen driving around without a proper spare.
Thanks Nick

Hi Nick,

I don't have one but am wondering where in the car you intend to keep it - if you can find one? Then where will you keep the jack/wheel brace etc? (Which jack can you use to lift these anyway other than a trolley jack?) Most of us either have a Silverline plug type repair kit or phone up Porsche Assist/other breakdown service.

When I'm back in the country at the weekend I will photograph the spare wheel I have and post it here - it is a Porsche one and I know you are looking for an alternative, but I couldnt find one that was going to work having looked everywhere for quite a while. I got the spare wheel because I seem to be magnetic to all things sharp and pointy on the road. They are not cheap new, do use your PCGB discount if you have to buy it from Porsche.

I agree with tscaptain, you may have a problem putting it anywhere because it is bigger than you imagine and I think the boot space is compromised in the turbo because of the 4wd system. I have a Carrera and it fits fine, but takes c. 40% of the space up (you also need a very large bag so there's something to put the real wheel in if the worst happens).

I did read about someone fitting a long threaded rod to mount the wheel in the boot, but that rod was directly in front of the petrol tank which seems like a risky place, I have two luggage straps diagonally fitted behind the panel with the puncture gunk etc in it and it holds the spare steady enough.

As for the jack, I bought a second hand Porsche one with the polystyrene insert to sit in the spare wheel, its aluminium and super light and does lift the car (you can also buy a hockey puck to protect the car jack point, though how you're supposed to get that and the jack under the car at the same time is a different story unless you drive onto something to elevate the sill. I also carry a long torque wrench to loosen the bolts as the brace I had was useless and it also ensures I tighten the bolts up properly.

Hope this helps

Hi

I have a friend that has a genuine Porsche skinny wheel that fits a Gen 1 turbo with ceramic brakes that he used to carry on long trips behind the passenger seat, he now has a 991 turbo that it doesn't fit.

PM me with your details if your interested & ill pass them on, i'm sure he would sell it at the right price. it was offered to me but i have a spare set of wheels so didn't need it.

Has anyone tried to get a 305/30/19 in the back seat? Not the lightest wheel/tyre combination. Even if it fits I don't think my back would be up to it! My money is still on Porsche Assist.[]

From an alternative perspective, what about something like puncturesafe which goes in as a preventative (or more accurately it sits in the tyre until there is a puncture and then it does its thing) as opposed to post-puncture application.

In theory it is a sound idea, though would probably need loads for 911 tyres - I have not worked it out yet.

I used some in my motorbike tyres last year for a trip to the Alps/Dolomites and it did not upset the handling, I do not have first hand experience of it working in anger, but it gave me piece of mind and the 'science' sounds right.

It is water soluble so no particular issues with gunking up wheels.

We are planning a trip over to Europe later in the year so I will probably use this stuff in the 997.

Interesting, Alex. Had a look at their website and used the calculator. For mine I would need 84 "units" where 35 units = 1lt. 1 car kit has 56 units and costs £45, therefore would need 2 car kits.

This would be my concern on where to put the punctured wheel. The 986 Boxsters came with a 'get you home' spare, with the advice to carry the punctured wheel in the passenger seat (no room behind seats on Boxsters remember, and too big for boot or frunk). The one thing it doesn't explain is where the passenger then goes!!

Assuming a 986 spare would fit, you may well pick a 2nd hand one up on eBay.

I also note that Cayennes have an option for a collapsable spare. Not seen one to know again if it would fit and how big it is, but may provide a little more space saving, although you then need a compressor or tyre pump as well!!

I knew it would need a lot...a 5 litre drum (71p/unit or £24/litre) will do two sets of tyres and cost per application would be:

- C2S (235/35 & 295/30) = 72 units = £51

- C4S/Turbo (235/35 & 305/30) = 74 units = £53

A 20 litre drum works out about £20 less per application (all figures assume no waste, which for me with a motorbike is realistic).

I would not try and get the stuff in big wheels without a pump, it took a while with bottles on the motorbike tyres, I could not imagine how long it would take by hand in a 305 section tyre!

Possibly an alternative worth considering?

I emailed PunctureSafe to confirm shelf life of opened containers (their FAQ references factory sealed), the response I got was:

Hi Alex, If you keep the cap on and store it in a cool place it should still last 5 years. best regards, Technical

Hi,

The part number is: 996.362.120.03 for the 18inch spare wheel.

By the way, it is heavy, if you want more load over the front axle - this will do nicely!

Its around 165mm wide and about 535mm in diameter.

This is it with the insert and Porsche jack.

The wheel straps run behind the wheel gunk and first aid kit panel (I know, its not clean, the wheel hasn't been out in a while!)

the straps are then looped diagonally over the wheel and tightened to hold it steady.

Hope this helps!

I do agree with the comments re Porsche assist, I drive a fair amount in Europe and even with that it would be my luck to have something go wrong at midnight somewhere...

 

[tscaptain]

Earlier Jo you mentioned having a large bag for the real rear wheel, should it need to be taken off. Where would you put it then?

 

[Lancerlot]

Part No for the emergency wheel for the turbo is 997 362 021 00

Regards,

Clive

As a suggestion, as we are all in agreement tht the rear or front wheels are rather large and heavy. Why not see your local engineering shope with the Towing Eye bolt and ask them to manufacture you a stud bolt that can be screewed in to the towing eyelet hole in rear bumper and that has a stopper welded to it and a further thread and locking nut with a washer that fits in to the outer center cap hole.

Then if you were to get a puncture, you can remove the flat and screw in the temporary storage stud on the back bumper and mount the flat tyre and rim. Fit your spare and still retain the space inside the car and Frunk....... just a thought.

Hi,

If I do have to take a wheel off it will go in the back inside a very large bag I carry (which is folded flat behind the spare wheel).

I know the wheels are huge but if I can get two full size hardshell suitcases in the back then a wheel will fit - of course providing there are no rear seat passengers!

Hope this helps!

 

[tscaptain]

It helps to explain it but doesn't help my back muscles! Having changed the wheels on many occasions to put on the track wheels and tyres I know how difficult it is just to lift the rears on to the guides let along manoeuvre it past the passenger seat into the back!

 

[angusc]

Expanding this topic slightly further, has anyone had run flat tyres fitted to their 997 Carreras? Last year I purchased a full set if Pirelli P Zeros for just under £1k but what would the likely costs of run flats be and any recommended brands? Are there any draw backs with running this type of tyres?

 

[tscaptain]

I (quick) search suggests that there are no run flats available in the appropriate sizes. SWMBO has run flats on the Beamer as that doesn't have a spare either. I think the ride is a bit firmer as the side walls are stiffer but that is irrelevant as you can't buy any for the 997 anyway! On the price side, I digress I know, I have just found a full set for mine (Bridgestone) for £670 delivered.
