992 GTS Centrelock puncture options

[Meeko]

Hi all,

I've managed to pick up a nail in the centre of one of my rear tyres. The car's done 2k miles and the tread is about 5.8mm for both rears. I read porsche recommend changing both if 30% wear (which is 5.5mm). So I'm right on the cusp.

Not sure what to do here.

1. Try and get it repaired somewhere and hope they don't damage the rim / have the correct tools for the centrelocks. I presume a repair would be safe? Recommendations of fitters in South West gratefully received if this is an option.

2. Just replace the damaged tyre and replace together as a pair down the line.

3. Replace the pair with PZeros and sell the old ones.

4. Replace the pair with Michellins, leaving fronts as PZero (can you mix on the car)?

5. Replace all 4 with Michellin and sell on the old ones.


Any thoughts?

Cheers,

Meeko

It's 3mm not 30%. Their approved cars have to have at least 4.5mm.

I think he means that Porsche recommend changing both tyres on the same axel if it’s over 30% worn. If it’s under 30% then they consider it ok just to change the punctured tyre.

As far as I know, Porsche won’t repair. I had a puncture after a few thousand miles and ended up getting a single new tyre from Porsche. I would have happily had a repair but Porsche wouldn’t and I didn’t want to risk a tyre shop damaging the centrelocks.

If it happened again tomorrow I’d use it as an excuse to stick two Michelin’s on (currently Goodyears) but I couldn’t justify that to myself at the time.

A good tyre fitter should be able to deal with the Porsche centre locks ...

Particularly if they specialise in tyres for these cars ???

[AMTony]

Removing a wheel with centre-locks is not rocket science.
All you need is a suitably rated torque wrench.

Whereabouts in the south west are you?

[Meeko]

Thanks everyone for your thoughts. I'm based in Bath, so Bristol is my OPC.

I'm nervous incase someone damages the wheels though, wonder if just bite the bullet and have the OPC change one.

Has anyone had a direct comparison of Pzeros compared to PS4S out of interest?

The OPC quoted £420 for replacement. A set of Michellins is £1478 less what I'd get selling the old ones.

It's my experience that secondhand tyres have a limited value ... and then there is the issue of shipping / collection / delivery ...

I despise centre locking wheels, they have no place on a road car. That aside, I'd return the car to the dealership or, a highly respected Porsche independent for tire replacement. We're talking about a £100k car, why would you scrimp on a few hundred quid.

Ah! Makes more sense

Steve Bull in Devizes will be able to sort you out.

You’re right about Porsche being dicks and not wanting to repair a mid-tyre puncture and quoting a ridiculous price for a replacement.
‘Oh it’s not safe sir”- what garbage…. I got I insistent with them and they stated it’s a Porsche GB policy. I said if they ever wanted me to spend another penny with them they’d better just plug it. They happily did so in the end and simply asked me to sign a disclaimer, which I was happy to do.

Load of cobblers, most respected indies don't do tyre changes in house, they remove them, get their local preferred partner to do the tyre swop and refit, OPC won't repair them at all and being forced into a replacement is ridiculous.

Plenty of decent tyre places have the appropriate kit and expertise to sort.

I would only use an OPC. I had wheels incorrectly fitted on a 997.2 GTS after some suspension work. They failed to put the wheels back correctly, and they came loose. If driven loose you need to replace several thousand pounds worth of components. They obviously replaced them FOC as it was their mistake. I doubt they would if a tyre fitter had made that mistake.

Meeko, you may find this thread interesting .

OP - I believe OPC have some movement in their prices & may negotiate, so there's that.

Otherwise you need to make sure you're using a specialist that has the tools to deal with these wheels. Centre locks need a special socket wrench & tightened to the correct nm settings. You may be surprised the length of the wrench if you've not seen one before. Quite comical imo!

Agreed they have said the same to me ,I didnt use that tactic because i didnt want to get into a situation of having no support on the car
