Puncture - HELP

The Porsche has a rear puncture which I am going to have to fix it. However a quick call to the Porsche Centre and they tell me they don't repair punctures, they just replace tyres and don't recommend puncture repairs!

Do any of the Porsche owners on here have any comments to make?
Michael

I'd phone your local tyre fitter and ask them. I can appreciate Porsche wanting to flog you a new tyre.
JohnC

I've just spoken to a client who used to work at Porsche and he reckons I should get it repaired. He says Porsche just have to cover themselves in case someone does 170mph down the Autobahn for hours on end.
PhilD

You didn't let Chris have a go did you?!
Stuntman

That's correct about what Porsche Dealerships would advise.

Fortunately the only time I've had a puncture in the Cayman (front right), all four tyres were pretty much due for replacement.  I used the tyre sealant to get me home (about 50 miles) and replaced all four shortly afterwards.  Repairing this tyre wasn't an option.

I probably would replace rather than repair, but surely it should be your friend's decision as well?

I'd agree with that. If you had it repaired and your friend then did 170 down the Autobahn, you might feel a bit sick.

Absolutely it is and I have sent him a text but I don't know when I will get a reply. My problem is that he isn't back till Sunday and having blown the tyre up, it is lasting about 45 mins/hr before the pressure drops noticeably.

I will have to move the car tonight and get it back to him on Sunday night but I can't really do it without either getting a new tyre or getting the puncture repaired.

I wouldn't compromise on safety and my friend will be informed all the way. It is just the practical aspects of moving it around that were concerning me and which fix I need before I can do that.

How much life does the tyre have and do you know where the puncture is?
Alf McQueef

A quality tyre fitting place will be able to tell you if it's repairable - it usually depends where the puncture is, if its at all near the sides, the tyre is toast. But otherwise, for UK use, if its not been run at very low pressures I personally have nothing against a repair.

I know now!!!

I took it round to the local specialist and there is a bloody big screw right through the shoulder. He has repaired it so that I can drive the car but will have a new tyre here for me tomorrow. No choice with this one.

The tyres have lots of life left in them but this is not something that can be repaired.

Significant loss of pressure suggests it's a screw picked up whilst you were driving it (car was fine when you first got it).

Hopefully your friend will chip you some spoons to reflect the partial wear on the tyre, but I don't think I would expect him to pay in full.

Still - that's not too bad - it would cost a bomb to hire a 911 for a few weeks.

However - make sure your tyre man doesn't scratch the alloy. Kwik fit and the like are buggers for that.

I wouldn't expect anything else other than me having to pay for the tyre. The place I go to do all the upmarket cars and the guys know how to change tyres without marking the alloys. Kwik-Fit would never see this car in my tenure.

You could use the compressor and tyre sealant if you need to drive the car a significant distance although the handbook recommends keeping it below 50mph if you do so.  When I had to do this myself, about 40 miles of my return journey were on the Motorway but it was a Sunday morning and I could tootle along in the inside lane at 55ish quite safely.  


Of course, you'd then need a replacement tyre sealant pack thingy as well...

EDIT - I see that you've had it repaired and a replacement tyre is on order

It's a shame that it has curtailed your enjoyment of the car for the time being, though.

I was expecting astronomical prices for a 295/30 x 20 PZero but it is actually less than the price of a runflat for the back of mine so, much as it hurts, I was anticipating worse.
Martin

Have you made sure it's an N spec tyre (assuming the other rear is)?

Runflats are ridiculously expensive, it would save me £20 a tyre putting Pilot Sports on mine, a lot more if I chose a comparable tyre.  I won't, but it's a little tempting.  They're about £30-40 more than the 19" rears on the Boxster.
PhilD

don't you have to change both sides or is the other side pretty new?
JohnC

Pardon my ignorance but what is an N spec tyre?

The guy knows what car it is for and that it needs to be the 101Y version, whatever that is!

The tyres are pretty new. I doubt they have done more than about 2000/2500 miles

Tee hee !   Chance would be a fine thing.... tomorrow I shall be having a go in something a little faster than a 911 (my combined 2015 Christmas and birthday pressie from younger daughter).

I've never known a car like my old Ka for picking up punctures.... 3 in less than 9500 miles and 20 months. If I'd kept it to the "true" end of the PCP, I'd still have another 3 weeks to go in it
Martin

They are Porsche specific rated tyres and if it's under warranty, must be fitted.  They range from N-0 (newest design) to N-4 and you shouldn't even mix different N ratings of the same tyres according to Porsche.

They aren't any more expensive than non N rated ones, surprisingly.

Does it state on the tyre what N rating it is and if so where does it show it?
JohnC

The only "N" I can see on the tyres is N0 and it is on all the tyres.

That's what you're looking for, the new one needs to be the same.  I bet your tyre man will know that and have ordered the right tyre, but worth double checking.
JohnC

Thanks Martin.

I will phone him in the morning.
Martin

No problem.

Just looked on Blackcircles and the N0 rated P Zero is £6 cheaper than the normal version.  Not what you'd expect.
JohnC

All sorted today. The guy who ordered the tyre already knew about the N rating and had seen that they were N0 tyres.

£240 supplied fitted and balanced. A bit more than Black Circles but it's done  and dusted today.
Stuntman

That's not too bad a price.  Hope you keep enjoying your time with the car.

Is it possible to do anything else?

Porsches are good when they're working properly and not throwing you a big bill...
