Had to call out Porsche Assist (covered by a warranty extension) tonight as the TMS showed a pressure loss in the rear tyre on my 991.2 C2. AA arrived with 20 minutes and he took the wheel off and found a small screw had gone straight through. He recommended a temp plug rather than using the goo stuff and I’ve managed to get home safety after two and a half hours at 50mph max.

What’s the proper course of action now? The tyre had only done 10000 miles and has plenty of tread left but should I bin both the rears via the nearest Porsche dealer, or can I get a proper repair at a reputable tyre place? Thoughts would be appreciated.

P.s mpg topped 40 but I was overtaken by plenty of i10’s….

Depends where the puncture is. If in the centre 80% of the tread, then it should be repairable.

Well the last time I had a puncture the OPC said that it was an 'N' rated tyre and they wouldn't repair it , then I spoke with Kwik Fit asked about the 'N' rated aspect and was told they would repair it but would point out it was that type of tyre so it would be my choice , the car was only 3 months old with about 2k , after some thought opted for the new tyre

I've got an N1-rated Cup2 rear tyre that got a huge screw in it at around 1000 miles old. I had it repaired at my local tyre place and I've since done a few thousand miles on it including two track days. If a repair is possible then there's no reason not to have it done from a legal or safety point of view.

Porsche OPCs will always insist on replacement though, that's their policy.

Had similar on my Cayman, had it plugged ran it until the tyre needed replacing.... not an issue.

Had similar on bikes, done the same... done 160+ across Germany without issue.

Had a puncture on my previous N rated Michelins on my 996. Repaired by the local tyre place with no problems.

Thanks everyone

Bournemouth OPC didn’t return my call, Portsmouth quoted £350 a tyre. My worry is whether a repair voids the extended warranty in any way? Portsmouth also questioned why Porsche Assist didn’t trailer my car straight to a dealer….In theory I’m only supposed to do 100 miles on the AA temp repair and I did that getting home.

In the old days a repair would mean you would fail the warranty renewal 111-point check, but as they seem to have disappeared I can't see how a repair causes you any cause for concern unless they're re-instated. Worst case you have to buy a new tyre at that point, if it hasn't worn out by then...

Tyres are fully repairable if not inside 1 inch of tyre wall, plugged are as safe as houses and don’t listen to gush from OPCs

A good repair shouldn't be a worry. Finding a "reputable tyre place", may be more of an issue!

Lost count of the number of tyres I have had repaired due to a small screw or nail through middle areas of the tread - always to BS 159 safety standards.

I think there are two options, I’ve had the hole plugged with no issues, but also, a plug and vulcanised seal on the inside. Think this had an MTR patch for belt and braces.

OPCs won’t do repairs but suspect this is a commercial policy. Why do a £20 repair when you can sell two £300 tyres.

In my distant memory, plugging was the original method used to repair tubeless tyres, when they first appeared. Later this was deemed to be unreliable for a permanent repair, and the "mushroom" type was introduced. This obviously involves removing the tyre, so should be done by a professional operation, but if they are prepared to repair it (i.e. they feel that the puncture is in a suitable place to be repaired safely) then there should be no problem to run the tyre for the rest of it's useful life. In terms of a suitable place to repair or buy tyres, I can recommend Black and Rounds at Silverstone, they are very professional and reasonably priced, they can also carry out full alignment set up with good equipment and expertise, they also carry out set up work for a local Porsche race and track day team, they really know what they are doing, and worth making the journey if you're not local. Usual disclaimer .....

I’ve had plenty of tyres on quick cars repaired and never had an issue. £10 repair vs £300 for a new tyre is an easy decision.

Can’t see how anyone would know your tyre was repaired without you telling them. I wouldn’t worry about it.
